According to the classification of PA, even if the ABS products are made, they can only be stretched and not impacted. It is understood that the plastic tube nylon sheet is developed in Europe and other countries, and has been well developed and successfully applied. The quality of sports equipment directly affects the level and popularity of sports, and the material is an important factor affecting sports equipment. Therefore, it is necessary to use a combination of screw, barrel, rubber head, rubber ring, and rubber gasket with strong feeding capacity and high wear resistance.
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. Long-term use temperature -80-260 degrees, excellent chemical resistance, corrosion resistance to all chemicals, friction coefficient in plastic, and good electrical properties, and its electrical insulation is not affected by temperature , 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. Harm: 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.

Commonly used anti-friction materials include graphite, molybdenum, PTFE powder, silicone oil, etc., and the amount is generally in the range of 3% to 15%. PA6 strong series: It has good abrasion resistance, heat resistance, oil resistance and chemical resistance. It also greatly increases the water absorption and shrinkage of the raw materials, and has excellent dimensionality and excellent mechanical strength. Xuzhou Tengfei Engineering Plastics is a high-tech enterprise specializing in the R&D, production and sales of engineering plastics, strong nylon and modified engineering plastics. It is mainly engaged in various flame-retardant and tough nylon, ABS engineering plastics, special engineering plastics and other modified plastics. Hotline:. The specific resistance of carbon fiber reinforced nylon is related to the type of fiber. At 25°C, the high modulus is 775, and the degree of carbon fiber reinforced nylon is 1500 per centimeter.
