Curves A, B, and C represent material A, material B, and material C, respectively; the following are the same. Automobile>Quantification refers to the weight of the automobile as much as possible on the premise of ensuring the strength and performance of the automobile, so that the power of the automobile, fuel consumption, and exhaust pollution. In addition, other applications of wear-resistant materials include urinary catheters, sleeves, transmission devices and vacuum tubes. PC/ABS alloy has a complex microstructure, and its microstructure can significantly improve the mechanical properties of the alloy. 2. Nylon alloying will become the mainstream of the development of modified engineering plastics.
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.

3. The cooling rate of strong nylon 6 and strong nylon 66 are different: PA6 takes a long time to form. 3. The glass fiber nylon material is easy to absorb water. If it is not fully used, it must be re-baked next time. The water content in the material is too high, causing bubbles and flashing. Under the action of the initiator, annealing treatment is required after injection molding. At present, baby stroller parts have basically realized plasticization, and the development of baby strollers with plastics instead of steel is driving the continuous development and innovation of modified plastics in the application of strollers to a broader field.
