Although it can be between the glass fiber and the base material, the flame retardant properties of glass fiber strong PA6 and flame retardant glass fiber strong PA6 composite materials are prepared by a twin-screw extruder. For glass fiber-strength PA6 composites, the forming conditions will also have a direct impact on the performance of PC/ABS blend products. The flow characteristics of ABS are non-fluid, and its melt viscosity is related to processing temperature and shear rate, but it is more to shear rate. Technical factors: More than 1,000 polymers have been discovered so far. The particle size of wollastonite should be determined according to the content of wollastonite in nylon 66.
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.

However, the long-term thermal effect of such antioxidants on nylon 66 needs to be further studied. For example, adding a certain amount of toughening agent POE to PA66/GF can ensure that the composite material has better mechanical properties and higher impact toughness. The class is a chain terminator that can terminate the radical chain reaction; the second class of agents can initiate a radical reaction. Mechanical equipment: used to manufacture various gears, racks, worm gears, worms, bearings, cams, bolts, levers, crankshafts, ratchets, as well as some mechanical parts guards, covers, frames and other parts. With the rapid development of the plastics industry, engineering plastics continue to expand in terms of strength and precision, and the scope of plastic products is constantly expanding, such as: household appliances, instrumentation, construction equipment, automobile industry, daily hardware and many other fields, plastic products The proportion is increasing rapidly.
