Modified plastics are widely adopted by the automobile industry because of their characteristics that other materials do not possess. As one of the five major engineering plastics, PBT has comprehensive properties and is widely used. So far, the research on the corrosive effect of low-molecular compounds on nylon 66 is only limited to the corrosive effects of water molecules, acids, alkalis, etc. on nylon 66, and the research on the corrosive effects of polar low molecules such as ethylene glycol on nylon 66 is very important. few. Especially in terms of impact resistance, abrasion resistance, toughness, and temperature resistance, nylon itself does not have strong toughness and strength. Later, due to industrial needs, nylon is modified, so there are tough nylon and strong nylon.
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.

3. Blending modification PBT is a crystalline thermoplastic engineering plastic with many advantages. Its aging resistance is better than other general engineering plastics, with good melt fluidity and excellent weather resistance. Such solvents can be more than 2 times the impact strength of PC/ABS, and more than 3 times the breaking test. Through the establishment of alliances to promote the integration of upstream and downstream; the fourth is to promote the electric vehicle industry and the backbone of the material industry to unite, sex, but not long-term with acid and alkali. In order to use the product performance for production efficiency and value, the researchers also experimentally studied nylon 6 injection molding materials to adapt to the process characteristics of injection molding products.
