Common escalator handrails, new bicycle plastic rims and other periodic fatigue effects are very obvious, and PA is often used. The strength of PA66 composite is related to the strength of the filler and the degree of bonding between the filler and PA66. Function: For example, when nylon contains silicon powder, silicon bromide will be formed on the surface, which plays a role in the flame retardancy of nylon. The impact strength of the product is low, mainly after modification,
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.

As far as the current development of the plastics industry is concerned, 4. Hardness and wear resistance: When you require good hardness, low price, and no requirements for temperature, choosing POM is a very macro choice. In the selection, you need to consider more issues. You can’t just choose a material, otherwise it will be disrespectful to you. 3. Powder materials are widely used in plastics, which can save a lot of synthetic resins based on petroleum. However, in the past 30 years, the phenomenon of dust flying around production and enterprises is currently vigorously controlling pollution and controlling PM2.5 indicators. The strict requirements are faced with severe tests.
