The reaction time is short, so that to a certain extent, the flame retardant has a negative effect on the performance of the material. , The better the toughness effect; D. The influence of the interface strength between the toughening agent and the matrix resin The influence of the interface bond strength on the toughness effect is different for different systems; E. The influence of the structure of the elastomer toughening agent and the type of elastomer, crosslinking degree, etc. related. , Good toughness, harden earlier than other parts,
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.

Melting point and elasticity: Dragon 6 has a melting point of 220C and nylon 66 has a melting point of 260C. It can significantly increase the heat resistance of polymers. Large arcs are used instead of sharp corners. Plastic products are not many as structural load-bearing parts, but as daily necessities, more attention should be paid to abrasion resistance, because if the agent is added As a result, the hardness of plastic products will inevitably affect their wear resistance, which in turn affects the service life of plastic products. For nylon materials,
