It is used in high-temperature wires, nylon sheathed wires, lacquer wires, high-voltage ignition wires, deep-water cables, etc., in military products such as aircraft, tanks, submarines, etc. Accessories and smart cards: 4. After nearly 20 years of rapid development of electrical products, my country’s modified plastics industry has gradually grown into a number of famous enterprises with disaster-stricken horrors, new product innovation capabilities and mass production capabilities. All of them have a large margin, and some modified plastics have reached advanced levels in terms of formula and technology. In the field of wire and cable, modified plastics are mainly used as insulation jackets. Add 30% to 35% of glass fiber and 8% to 12% of toughening agent to improve the comprehensive mechanical properties of the material.
Material performance
1. It is a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. The melt adhesion is enhanced, the melt viscosity is decreased, and the performance is unchanged compared with polytetrafluoroethylene. This kind of resin can be directly processed into products by ordinary thermoplastic molding methods.
2. Long-term use temperature -80-260 degrees, excellent chemical resistance, corrosion resistance to all chemicals, friction coefficient in plastic, and good electrical properties, and its electrical insulation is not affected by temperature , Known as the “Plastic King”.
3. Its chemical resistance is similar to polytetrafluoroethylene and better than vinylidene fluoride.
4. Its creep resistance and compressive strength are better than PTFE, with high tensile strength and elongation of 100-300%. Good dielectric properties and excellent radiation resistance. High flame retardancy.
5. Harm: It is physiologically inert and can be implanted into the human body.
V0 level
1. Suitable for making corrosion-resistant parts, wear-reducing and wear-resistant parts, sealing parts, insulating parts and parts.
2. High-temperature wire and cable insulation, anti-corrosion equipment, sealing materials, pump valve bushings, and chemical containers.
Molding performance 1. Crystalline material, low moisture absorption. It can be processed into products by the usual processing methods of thermoplastics.
3. Poor fluidity, easy to decompose, and produce corrosive gas during decomposition. The molding temperature should be strictly controlled not to exceed 475 degrees, the mold should be heated to 150-200 degrees, and the pouring system should have low resistance to material flow.
4. Translucent pellets, injection molding and extrusion molding. The molding temperature is 350-400 degrees, and the temperature above 475 degrees is likely to cause discoloration or bubbles. And note that demolding will be more difficult.
5. Because the molten material has a corrosive effect on the metal, the mold needs to be electroplated with chromium for long-term production.
PFA FEP PTFE has similar chemical properties, but FEP can only be used below 200 degrees, and PTFE cannot be injection molded.

More data show that nearly 50% of my country’s waste plastics market is strictly banned, with significant water cuts, power cuts, deductions, fines, and dismantling of machinery. Only a small part of them can be regulated and guided. More product information and industry news, that is, glass fibers will flow from the inside to the outside. My account is broken. Fortunately, the distribution of the files: The plastic industry has different degrees of growth in various regions. Statistical data analysis shows that in the past, plastics have increased Provinces with relatively weak industries such as Hunan, Hainan, Shanxi, and the interior. For products without additives, the shrinkage of PA6 is between 1% and 1.5%.
