It can only be dissolved in strong polar solvents. My point is that this kind of guidance is of limited significance. Fortunately, more and more customers have understood that suppliers cannot control the current situation. The lightweight of automobiles has enabled the rapid expansion of the plastics market including polypropylene, polyurethane, polychlorine, thermosetting composite materials, ABS, nylon and poly. Several opinions on accelerating the development of circular economy pointed out that in the first 20 years of this century, my country will be in the stage of accelerated development of industrialization and urbanization, and the resources and forms facing it are very severe.

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.

The drying temperature is above 80℃, and the time is above 2 hours. The details should be carried out according to the supplier’s information. This is because the introduction of the flame-retardant structure hinders the original molecular chain structure, hinders the molecular chain lattice, and affects the crystal properties of the material. The XRD analysis results of -PA66 are consistent, and it also shows that the crystallization performance and melting behavior are two. Those are closely related. PC alloy products have the characteristics of high impact strength, creep resistance, heat resistance, low water absorption, and excellent dielectric properties. Among the halogen-based flame retardants, it has a high flame retardant efficiency, and the arc resistance of the product, the limitation of storage and color, greatly application in nylon. It is a general trend that PE pipes replace PVC pipes.
