That is to say, general macromolecules or high polymers are polymerized by ordinary low-molecular monomers. Therefore, the intermolecular structure is large, and the epoxy group on the chain extender molecule only has a chain extension reaction with a small amount of nylon 66 end group. The nylon woven material has a shock absorption effect and a low density.
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 reduced, 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 in the human body.
V0 level
1. Suitable for making corrosion-resistant parts, wear-reducing 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 air bubbles. And pay attention to demoulding 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.

After granulation, a spline is made to perform flame retardant performance on the material through LOI and vertical means. , In addition, in order to add the interval, the formulation will introduce agents, these small molecules are also VOC. 4. The packing pressure and the pressure will fade away. Whether the packing pressure and time are set reasonably or not, directly affects the size of the internal stress of the part. It is polar and will attract each other due to the action of hydrogen bonds. PA6 for fishing nets accounts for about 6%.
