PPS information The resin matrix of thermoplastic composites involves general and special engineering plastics, and PPS is a typical representative of special engineering plastics, commonly known as "plastic gold". Performance advantages include the following aspects: excellent heat resistance, good mechanical properties, corrosion resistance, self-flame retardant up to UL94 V-0 level. Because PPS has the advantages of the above properties, and compared with other high performance thermoplastic engineering plastics and has the characteristics of easy processing, low cost, so it becomes an excellent resin matrix for manufacturing composite materials. PPS composite material PPS filling short glass fiber (SGF) composite material has the advantages of high strength, high heat resistance, flame retardant, easy processing, low cost, and has been applied in automotive, electronics, electrical, machinery, instruments, aviation, aerospace, military and other fields. PPS filling long glass fiber (LGF) composite material has the advantages of high toughness, low warpage, fatigue resistance, good product appearance and so on. It can be used in water heater impeller, pump shell, joint, valve, chemical pump impeller and shell, cooling water impeller and shell, household appliance parts and so on. What are the specific differences between short glass fiber (SGF) and long glass fiber (LGF) reinforced PPS composites? 1. Mechanical property analysis The reinforcement fiber added in the resin matrix can form a supporting skeleton, and the reinforcement fiber can effectively bear the external load when the composite is subjected to external force. At the same time, energy can be absorbed by fracture, deformation and other ways to improve the mechanical properties of resin. The tensile strength and bending strength of the composites are gradually increased by increasing the amount of glass fiber. The main reason is that when the glass fiber content increases, more glass fiber in the composite material can withstand the action of external force. Meanwhile, due to the increase in the number of glass fibers, the resin matrix between the glass fibers becomes thinner, which is more conducive to the construction of glass fiber reinforced frame. Therefore, with the increase of glass fiber content, more stress is transferred from resin to glass fiber under external load, which effectively improves the tensile and bending properties of composite materials. The tensile and bending properties of PPS/LGF composites are higher than those of PPS/SGF composites. When the glass fiber mass fraction is 30%, the tensile strength of PPS/SGF and PPS/LGF composites is 110MPa and 122MPa, respectively. The bending strength was 175MPa and 208MPa, respectively. The flexural elastic modulus were 8GPa and 9GPa, respectively. The tensile strength, bending strength and bending elastic modulus of PPS/LGF composites are increased by 11.0%, 18.9% and 11.3% compared with PPS/SGF composites, respectively. PPS/LGF composites have higher length retention rate of glass fiber. Under the condition of the same glass fiber content, the composites have stronger load resistance and better mechanical properties. When the glass fiber content is low, the impact strength of the composite decreases. The main reason is that the lower glass fiber content cannot form a good stress transfer network in the composite material, so that the glass fiber exists in the form of defects under the impact load of the composite material, resulting in the overall impact strength of the composite material is reduced. With the increase of the glass fiber content, the glass fiber in the composite can form an effective spatial network, and the reinforcement effect is greater than that of the glass fiber tip. Under the action of external load, the external load can be transferred to the reinforced fiber better, thus improving the overall performance of the composite. In the PPS/LGF system, the length of the glass fiber is longer and the spatial network is more dense. The reinforced glass fiber has greater bearing capacity and better impact strength. When the mass fraction of glass fiber is 30%, the impact strength of PPS/LGF is increased by 19.4% from 31kJ/m2 to 37kJ/m2, and the notch impact strength is increased by 54.5%(from 7.7kJ/m2 to 11.9kJ/m2). 2. Thermal properties analysis of PPS/SGF and PPS/LGF composites When the mass fraction of glass fiber is 30%, the thermal deformation temperature of PPS/SGF composite and PPS/LGF composite reaches 250℃ and 275℃, respectively. The thermal deformation temperature of PPS/LGF composite is 10% higher than that of PPS/SGF composite. The main reason is that the introduction of glass fiber makes the network skeleton of reinforced fiber formed inside the composite material, which greatly improves the heat resistance of the composite material. The size of glass fiber in PPS/LGF is longer, and the heat resistance improvement advantage is more obvious....

Polyamide 12 filling long glass fiber The recommended long-term working temperature of polyphenylene sulfide resin (PPS) is 220~240℃. The material has good thermal stability, and its mechanical properties remain at about 80% and 60% of their original values at 100°C, 160°C and 200°C, respectively. The material has excellent creep resistance and fatigue resistance at room temperature. The material also has excellent resistance to acids, alkalis, salts, organic solvents and other media, except for oxidizing acids and strong oxidizing media, and is almost insoluble in any chemical solvent below 170°C. It is especially suitable for hydrofluoric acid, halogenated hydrocarbons and chloride ion corrosion resistance. PPS is a flame retardant material with an oxygen index of 46 to 53, better than most engineering plastics. Polyphenylene sulfide has high resistance and low dielectric constant electrical properties, and can maintain good electrical properties under high temperature and high humidity conditions. In addition, the mechanical properties of the resin material are not very outstanding because it has good affinity with glass fiber, carbon fiber, inorganic filler and solid lubricant, and the modification is good, so the particles used in injection molding are mainly modified and reinforced by various fibers and inorganic fillers. LGF & SGF Nylon particles of ordinary glass fiber: Size size is about 3-4mm, length to width ratio 50-250 Long glass fiber nylon particles: Size is about 10-12mm, aspect ratio >400 In addition, the distribution of glass fiber in the two kinds of particles is also different. Compared with SGF, LGF has improved rigidity, strength and modulus, especially the notched impact performance has been greatly improved. Compared with SGF, LGF has improved rigidity, strength and modulus, especially the notched impact performance has been greatly improved. The rigidity retention rate of long glass fiber is better than that of short glass fiber, and long glass fiber is more resistant to heat aging. The creep performance is affected by time, temperature and load. At 120℃ and 40Mpa load, the creep of long glass fiber is significantly better than short glass fiber. This is critical for parts with long term static pressure, and long glass fiber can be tried when short glass fiber cannot meet the requirements. Shrinkage is crucial to the size of the part. The transverse shrinkage of short glass fiber material is much higher than the longitudinal shrinkage, and the anisotropy is more serious, resulting in difficult to control the size of the part and obvious shrinkage. In contrast, the transverse and longitudinal shrinkage rates of long glass fiber materials are very close, showing isotropy, improving the risk of part warpage and making the dimensions more controllable.

Polyphenylene sulfide PPS is one of the typical representatives of special engineering plastics, with a linear structure of alternating benzene rings and sulfur atoms. In the condensed structure, PPS is easy to crystallize, crystallinity of nearly 70%, therefore, has good thermal stability, chemical stability and dimensional stability, etc. PPS mainly has the following five performance advantages. (1) excellent heat resistance. pps melting point of more than 280 ℃, heat deflection temperature of more than 260 ℃, and after high-temperature heat aging treatment, the strength retention rate is high. (2) since the flame retardant. PPS itself has flame retardant, without adding flame retardants flame retardant level can reach UL94 V- 0 level. (3) good mechanical properties. PPS is a brittle material, has good creep resistance, high surface hardness, good wear resistance, and carbon fiber and other materials compound, but also shows good self-lubricating properties. (4) excellent chemical resistance, irradiation resistance. pps below 200 ℃ almost insoluble in any solvent, can withstand almost all inorganic substances, radiation dose up to 108Gy. (5) good processing properties. pps melt viscosity is low, as the resin matrix of composite materials, for the reinforcement of the flow of excellent wetting effect. As PPS has the above performance advantages, and compared to other high-performance thermoplastic resins and easy processing, low cost, so become an excellent resin matrix for the manufacture of composite materials. Long glass fiber Glass fiber is an inorganic non-metallic material with excellent performance, is a natural mineral with silica as the main raw material, add specific metal oxide mineral raw materials, mixed evenly, molten at high temperature, molten glass liquid flow through the funnel outflow, in the role of high-speed pull gravitational force is drawn and rapidly cooled and cured into a very fine continuous fiber. Glass fiber monofilament diameter from a few microns to more than twenty microns, equivalent to a hair of 1/20-1/5, each bundle of fiber original filament are composed of hundreds or even thousands of monofilaments. Glass fiber basic properties: The appearance of a smooth cylindrical surface, the cross-section is a complete circle, round cross-section to withstand the load capacity; gas and liquid through the resistance is small, but the surface is smooth so that the holding force of the fiber is small, not conducive to the combination with the resin; density is generally in 2.50-2.70 g/cm3, depending mainly on the glass composition; tensile strength than other natural fibers, synthetic fibers to be high; brittle materials, the elongation at break is very small ; water resistance and acid resistance is good, while alkali resistance is poor. It can be divided into continuous glass fiber, short glass fiber (SGF) and long glass fiber (LGF) by length classification. Long glass fiber is the most widely used glass fiber at present. And Xiamen LFT plastic composite company is focuses on the produce of long glass fiber compounds for many years. SGF VS LGF 1. The difference in size length Engineering materials long glass fiber and short glass fiber, literally means the difference in size length; more common short glass fiber size is about 0.2mm-0.6mm between; long glass fiber size is about 6mm-25mm between. 2. Performance strength differences Different lengths of glass fibers are different in their performance strength, the fiber length of long glass fibers in the composite material inside the impact strength than short glass fibers stronger. 3. Production process is different Production of long glass fiber, high requirements for raw materials, especially the manufacturing process requires the surface of glass fiber to be activated, the processing can not be flooded with glass fibers, as well as external leakage phenomenon occurs. Production of short glass fiber, because the size is generally no special requirements, so the production is relatively easy, the requirements for raw materials are not so high, the production costs for manufacturers low. 4. Different production and processing methods Long glass fiber production and processing methods generally use injection molding and molding; while most short glass fiber injection molding method.

PPS The molecular structure of PPS consists of benzene ring and sulfur atoms interarranged, the configuration is orderly, easy to form a high thermal stability of the crystal structure. At the same time, the molecular structure of PPS material has a highly stable chemical bond characteristics, the benzene ring structure makes PPS more rigid, and the sulfur ether bond (-S-) provides a certain degree of flexibility. PPS itself has good heat resistance, flame retardant, chemical resistance, should be a promising material, but unmodified PPS has some unavoidable defects: Difficult processing:  This is the biggest pain point of all high temperature resistant materials -- high processing temperature, no matter the molding process or processing energy consumption, will face great challenges. In addition, PPS is still prone to thermal oxidation crosslinking in the melting process, resulting in reduced fluidity and further improve the processing difficulty; Poor toughness: PPS molecular chain is rigid, the maximum crystallinity is as high as 70%, the elongation is low and the welding strength is not so good. As a result, the impact resistance of unmodified PPS is poor, which limits the application scope. High cost: PPS raw materials and general engineering plastics compared, the price is about 1-2 times higher, and some modified materials compared with low cost performance; Difficult coating: PPS surface coating and coloring performance is not ideal. While this is not a major problem for now, it is a limiting factor. PPS-LGF Long glass fiber reinforced composites can solve your problems when other methods of reinforced plastics do not provide the performance you need or if you want to replace metal with plastic. Long glass fiber reinforced composites can cost-effectively reduce the cost of goods and effectively improve the mechanical properties of engineering polymers, and increase the durability by forming long fibers to form a long-fiber-reinforced internal skeleton network. Performance is preserved in a wide range of environments. TDS for reference Application About us Xiamen LFT composite plastic Co., Ltd. is a brand-name company that focuses on LFT&LFRT.
