The product has a higher temperature during molding and replaces copper and other metals. Because polyamide has light weight, excellent mechanical strength, wear resistance and corrosion resistance, it is widely used to replace copper and other metals in machinery, chemical industry, instrumentation, and automobiles. Manufacturing bearings, gears, pump blades and other parts in other industries. It also has excellent comprehensive properties such as heat resistance, low temperature resistance, impact resistance, chemical resistance, easy processing and molding, and good surface gloss. The toughness of plastics mainly includes blended elastomer materials. Frame=Let’s talk about which elastomers are tough and which plastics. Plastic density The density of plastic is a kind of increase in the relative density of the original resin, mainly by adding heavy fillers and blending heavy resins.
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. The long-term use temperature is -80-260 degrees. It has excellent chemical resistance, corrosion resistance to all chemicals, the lowest friction coefficient among plastics, and good electrical properties. Its electrical insulation is not affected by temperature. Influence, 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. Non-toxic: 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. It is advisable to strictly control the molding temperature 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.

The impact strength is somewhat different. It is added 6 hours ago, then gradually increases, and tends to 14 hours later. The measured size of the sample is between mm*mm*mm. Its melt viscosity is low, and automotive engineering plastics mainly include polypropylene, polyurethane, abs material, HDPE, polycarbonate, nylon and so on. The importance of sufficiently large fillets cannot be overemphasized.
