PPA (Polyphthalamide) is polyphthalamide.PPA is a kind of thermoplastic functional nylon with both semi-crystalline structure and non-crystalline structure. It is prepared by polycondensation of phthalic acid and phthalenediamine. It has excellent thermal, electrical, physical and chemical resistance and other comprehensive properties.

PP is a polymer made by coordination polymerization of propylene monomer, and is one of the five general plastics PE, PP, PVC, PS and ABS.

PPA plastic PPA is made by polycondensation of aliphatic diamine or diamine with benzene ring-containing diamine or diamine. Compared to aliphatic polyamides, the introduction of a rigid benzene ring in the molecular chain results in a significant increase in mechanical strength and heat resistance, as well as a significant decrease in water absorption. Compared with aromatic polyamides, semi-aromatic polyamides have more flexible aliphatic structures in the molecular weight and lower melting points, which effectively improves the processing performance of aromatic polyamides. Because PPA has both the excellent performance of aromatic polyamide and aliphatic polyamide good molding processability, after years of development has become one of the most important varieties of special engineering plastics, is widely used in electronic and electrical appliances, automotive industry and other fields. PPA filling Long glass fiber compounds Glass fiber reinforced PPA composites are considered to be the best resin for replacing steel with plastic because of their high temperature resistance, high strength and low density. Long glass fiber reinforced PPA composites have better physical and mechanical properties than conventional short-cut fiber reinforced pellets.

PA6 material PA6 is one of the most widely used materials in the current field, and PA6 is a very good engineering plastic with balanced and good performance. The raw materials for the manufacture of nylon 6 engineering plastic are extensive and inexpensive, and it is not restricted by the technological monopoly of foreign companies. However, in order to make good use of this inexpensive and excellent material, we must first understand it. Today, we will start with glass fiber reinforced PA6 engineering plastics, because it is the most important category of PA6 engineering plastics. Just like any other engineering plastics, PA6 has advantages and disadvantages, such as high water absorption, low temperature impact toughness and dimensional stability is relatively poor. So engineers will use different methods to make PA6 better, which we call modification. At present, the most common method is to blend and modify PA6 with glass fiber (GF). Today, we will take a look at the mechanical properties of PA6 engineering plastics under the glass fiber GF system for reference and help us select materials. PA6-LGF 1. Influence of glass fiber content on PA6 engineering plastics We can find from the application and experiment that the content index is often one of the biggest influencing factors in fiber reinforced composites. As the glass fiber content increases, the number of glass fibers per unit area of the material will increase, which means that the PA6 matrix between the glass fibers will become thinner. This change determines the impact toughness, tensile strength, bending strength and other mechanical properties of glass fiber reinforced PA6 composites. In terms of impact performance, the increase of glass fiber content will greatly increase the notch impact strength of PA6. Taking long glass fiber (LGF) filling PA6 as an example, when the filling volume increases to 35%, the notch impact strength will increase from 24.8J/m to 128.5J/m. But the glass fiber content is not more is better, short glass fiber (SGF) filling volume reached 42%, the impact strength of the material reached the highest 17.4kJ/㎡, but continue to add will let the gap impact strength showed a downward trend. In terms of bending strength, the increase of the amount of glass fiber will make the bending stress can be transferred between the glass fiber through the resin layer; At the same time, when the glass fiber is extracted from the resin or broken, it will absorb a lot of energy, thus improving the bending strength of the material. The above theory is verified by experiments. The data show that the bending elastic modulus increases to 4.99GPa when the LGF (long glass fiber) is filled to 35%. When the content of SGF (short glass fiber) is 42%, the bending elastic modulus reaches 10410MPa, which is about 5 times that of pure PA6. 2. Influence of glass fiber retention length on PA6 composites The fiber length of the glass fiber also has an obvious effect on the mechanical properties of the material. When the length of the glass fiber is less than the critical length (the length of the fiber when the material has the tensile strength of the fiber), the interface binding area of the glass fiber and the resin increases with the increase of the length of the glass fiber. When the composite material is broken, the resistance of the glass fiber from the resin is also greater, so as to improve the ability to withstand the tensile load. When the length of glass fiber exceeds the critical, the longer glass fiber can absorb more impact energy under impact load. In addition, the end of the glass fiber is the initiation point of crack growth, and the number of long glass fiber ends is relatively less, and the impact strength can be significantly improved. The experimental results show that the tensile strength of the material increases from 154.8MPa to 164.4MPa when the glass fiber content is kept at 40% and the length of the glass fiber increases from 4mm to 13mm. The bending strength and notched impact strength increased by 24% and 28%, respectively. Moreover, the research shows that when the original length of the glass fiber is less than 7mm, the material performance increases more obviously. Compared with short glass fiber, long glass fiber reinforced PA6 material has better appearance warping resistance, and can better maintain mechanical properties under high temperature and humidity conditions. TDS for your reference PA6 can be made into long glass fiber reinforced material by adding 20%-60% long glass fiber according to the characteristics of the product. PA6 with long glass fiber added has better strength, heat resistance, impact resistance, dimensional stability and warping resistance than without glass fiber added. Following TDS show the data of PA6-LGF30. Application PA6-LGF has the largest proportion of applications in the automotive industry, by electronic and electrical applications, and also involving machinery and engineering ...

What is TPU? TPU(Thermoplastic polyurethanes) name is elastomer rubber. It is mainly divided into polyester type and polyether type, its hardness range is wide (60HA-85HD), wear resistance, oil resistance, transparent, good elasticity, in daily necessities, sports goods, toys, decorative materials and other fields are widely used, halogen-free flame retardant TPU can also replace soft PVC to meet more and more fields of environmental protection requirements. The so-called elastic body refers to the glass transition temperature is lower than the room temperature, elongation at break >50%, the external force removed after the good recovery polymer material. Polyurethane elastomer is a special category of elastomer, polyurethane elastomer hardness range is very wide, performance range is very wide, so polyurethane elastomer is a kind of polymer material between rubber and plastic. It can be heated plasticized and has little or no crosslinking in chemical structure. Its molecules are basically linear, but there is some physical crosslinking. This type of polyurethane is called a TPU. Why filling long glass fiber? 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.
