Mine is, this kind of guidance is very limited. High glass fiber content hole speed. , Welcome customers to call! Compared with general-purpose plastics, PA/PP has many advantages for molders, including the amount of moisture adhesion, drying time, injection temperature, and size. Solution: Generally, modified engineering plastic companies that produce flame-retardant nylon will have a color matching and a dedicated color matching mixer. In the modified nylon filled and modified, color masterbatch can be added to fully and evenly color. There will be no uneven products.
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. 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 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.

In order to promote graphene technology and its application research. , Since the types of matrix materials of thermoplastic composites are much more than that of thermoset composites, the degree of material selection and design is also greater. 8. Tableware: high temperature resistance, food grade, high fluidity, strong, PA66+30%GF. It can reduce the timing torque of the automobile engine by as much as four times,
