If the improper effect of pigments, agents, or materials containing GF nylon are used for plastic products or baby strollers, the plastic will be degraded. According to the types of monomer units, block copolymers can be divided into di-block, tri-block, and multi-block copolymers. Why do stress marks appear? The reason is that there is a benzene ring in the strong nylon chain and the molecular orientation is different. The oriented molecular chain has to resume the curl state, but the entire macromolecular chain has been cooled and frozen, and the product has the ability to break the house. , The formation of stress marks. Material properties have tended to
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. The molding temperature should be strictly controlled 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.

Manufacturers can completely recycle the unpainted plastic parts, thus avoiding the waste of plastic and saving resources. Therefore, Fig. TPV is applied to auto parts Fig. Car sealing strip Fig. Airbag 2. Sealing strip for construction and transportation power parts; Expansion joints of buildings, roads and bridges; Seals for water supply and drainage pipes, water irrigation control valves and so on. For a constant rubber content, the rapid transition from brittleness to toughness occurs at the critical particle size of the particles, which means that the distance between particles must be equal to or less than the critical value. PC/ABS has the comprehensive characteristics of both PC and ABS.
