PP filling Long glass fiber PP (polypropylene), as one of the general-purpose plastic materials, has a large production volume and low price, as well as excellent comprehensive performance, good chemical stability, and better molding and processing performance. However, the shortcomings of PP, such as low strength, low service temperature, low hardness, and poor low-temperature impact strength, have seriously limited its application areas. Therefore, engineers by adding glass fiber, calcium carbonate and other reinforcing materials in PP, and when the length of the glass fiber and other lengths exceed the critical size, the mechanical properties are improved by leaps and bounds! Long Glass Fiber Reinforced PP (LFT-PP) is a very typical thermoplastic composite material, which is generally a column of particles with a length of 12 mm to 25 mm and a diameter of about 3 mm. In these particles, the glass fibers have the same length as the particles, the content of glass fibers can vary from 20% to 70%, and the color of the particles can be matched according to customer requirements. PP-LGF advantages 1. longer fiber length, significantly improve the mechanical properties of the products. 2. high strength, good impact resistance, especially suitable for furniture, automotive parts. 3. high creep resistance, good dimensional stability, high precision parts molding. 4. excellent fatigue resistance. 5. better stability in high temperature and humid environment. 6. molding process fiber can be in the molding mold relative movement, fiber damage is small.

PP-LGF Among many composite materials, long glass reinforced polypropylene material (PP-LGF) has gained more popularity for its low price, excellent mechanical properties and environmental friendliness.Compared with short glass fiber reinforced polypropylene material (PP-SGF), PP-LGF has more advantages in strength, stiffness, warpage, fatigue resistance, notch impact strength and dimensional stability, so products produced with PP-LGF can further achieve weight and cost reduction. The length of PP-LGF particles produced by our company is generally 8mm~15mm, in which the content of glass fiber can reach 20%~60%, and the retained length of glass fiber in the particles can reach 1mm~3mm, compared with PP-SGF materials whose retained length of glass fiber is only 0.2mm~0.4mm, PP-LGF can guarantee the following characteristics due to the three-dimensional network structure of its internal fiber.  1. Low density: The use of long glass fiber reinforced composite material instead of steel is an effective way to reduce the weight of the product.  2. High strength: The composite material with modified resin and different length of fiber has high mechanical strength, good rigidity and impact performance, which can replace steel plate to make coverings or structural parts. 3. Low cost: The use of long glass fiber reinforced composite materials instead of metal materials can simplify the design of complex metal parts and achieve the purpose of forming complex parts at one time. 4.

What is PA6 plastic? polyamide (PA), usually called Nylon, is a hetero-chain polymer containing amide group (-NHCo -) in the main chain. It can be divided into aliphatic group and aromatic group. It is the earliest developed and the most used thermoplastic engineering material. Polyamide main chain contains many repeated amide group, used as a plastic called nylon, used as a synthetic fiber called nylon. A variety of different polyamides can be prepared according to the number of carbon atoms contained in binary amines and dibasic acids or amino acids. At present, there are dozens of polyamides, among which polyamide-6, polyamide-66 and polyamide-610 are the most widely used. Polyamide-6 is an aliphatic polyamide, with light weight, strong strength, wear resistance, weak acid and alkali resistance and some organic solvents, easy molding and processing and other excellent properties, widely used in fiber, engineering plastics and thin films and other fields, but PA6 molecular chain segment contains strong polarity amide groups, easy to form hydrogen bonds with water molecules, The product has the disadvantages of large water absorption, poor dimensional stability, low impact strength in dry state and low temperature, strong acid and alkali resistance. Advantages of nylon 6: High mechanical strength, good toughness, high tensile and compressive strength. Outstanding fatigue resistance, the parts after repeated bending can still maintain the original mechanical strength. High softening point, heat resistant. Smooth surface, small friction coefficient, wear-resistant. Corrosion resistance, very resistant to alkali and most salts, also resistant to weak acids, oil, gasoline, aromatic compounds and general solvents, aromatic compounds are inert, but not resistant to strong acids and oxidants. It can resist the corrosion of gasoline, oil, fat, alcohol, alkaline and so on, and has good anti-aging ability. It is self-extinguishing, non-toxic, odorless, good weather resistance, inert to biological erosion, and has good antibacterial and mildew resistance. Has excellent electrical performance, good electrical insulation, nylon volume resistance is high, high breakdown voltage resistance, in dry environment, can work frequency insulation material, even in high humidity environment still has good electrical insulation. Light weight, easy dyeing, easy forming, because of low melting viscosity, can flow quickly. Disadvantages of Nylon 6: Easy to absorb water, water absorption, saturated water can reach more than 3%. Poor light resistance, in the long-term high temperature environment will oxidize with oxygen in the air, the color turns brown at the beginning, and the subsequent surface is broken and cracked. Injection molding technology requirements more strict, the existence of trace moisture will cause great damage to the quality of molding; The dimensional stability of the product is difficult to control because of thermal expansion. The existence of sharp Angle in the product will lead to stress concentration and reduce the mechanical strength; If the wall thickness is not uniform, it will lead to the distortion and deformation of the parts. High precision of equipment is required in post-processing. Will absorb water, alcohol and swelling, not resistant to strong acid and oxidant, can not be used as acid-resistant materials. Why filling Long Glass Fiber? PA6 has excellent properties such as light weight, strong strength, abrasion resistance, weak acid and alkali resistance and some organic solvents, and easy molding and processing. It is widely used in the fields of fibers, engineering plastics and films. However, the molecular chain segment of PA6 contains highly polar amide groups, which are easy to form hydrogen bonds with water molecules. The product has the disadvantages of large water absorption, poor dimensional stability, low impact strength in dry state and low temperature, strong acid and alkali resistance. With the development of science and technology and the improvement of life quality, the defects in some properties of traditional PA6 materials have limited its development in some fields. In order to improve the performance of PA6 and expand its application field, PA6 should be modified. Filling enhancement modification is a common method for physical modification of PA6. It refers to the modification of PA6 by adding fillers such as glass fiber and carbon fiber into the matrix to significantly improve the mechanical properties, flame retardant properties, thermal conductivity and dimensional stability of the material. What is application of PA6-LGF? Modified section of 30% long glass fiber reinforced PA6 is the ideal material for processing power tool shell, power tool parts, engineering machinery parts and automobile parts. Its mechanical properties, dimensional stability, heat resistance and aging resistance have been significantly improved. The fatigue resistance strength is 2.5 times that of unenha...
