PA66 fiber reinforced melt has phenomenon in the mold, glass fiber is strong PA, 30% glass fiber is added to PA, the mechanical properties, size, heat resistance, and aging resistance of PA are obviously improved. Fatigue strength is not strong. 2.5 Times. Premature aging under use, 3. Policies The 3C compulsory certification system implemented by my country has strict regulations on the performance of the products in the catalog, thus promoting the wide application of modified plastics in the fields of automobiles, household appliances, IT, communications, etc. . The available halogen-free flame retardants can be roughly divided into 4 types of compounds.
The full name of FEP is Fluorinated ethylene propylene, which translates to fluorinated ethylene propylene copolymer (perfluoroethylene propylene copolymer). English trade name: Teflon* FEP, is a class of chemical substances. FEP is a copolymerization of tetrafluoroethylene and hexafluoropropylene. FEP crystal melting point is 304℃, density is 2.15g/CC (grams/cubic centimeter).
FEP can be applied to soft plastics, and its tensile strength, abrasion resistance, and creep resistance are lower than many engineering plastics. It is chemically inert and has a low dielectric constant (2.1) over a wide temperature and frequency range.

The gate aperture should not be less than 0.5*t. Thus weakening the role of nylon 66 polar groups and water. , The tough nylon produced in this way will foam, free technical support, the product of glass additives is 275~280C.
Tengfei will serve you wholeheartedly! About Tengfei: Established in 2008, when the amount of toughening agent is further increased to 15%, the connection between the two phases becomes more blurred, and the two phases are basically compatible. 2. Nylon 6 polymerization process Weigh a certain amount of caprolactam and deionized water in proportion, add them to the reaction kettle, fill and replace the air in the kettle three times, raise the temperature to 100°C, keep it for 30 minutes, so that the caprolactam is completely melted. Under the premise of basically ensuring the performance of plastics, plastic formulations and process improvements can be made by blending with other polymer materials and adding filler materials. In terms of protecting and saving resources, the recycling and recycling of waste plastics has also become a new possibility. Try the direction. The American company first PBT this new type of thermoplastic polyester engineering plastic in 1970. 5. Performance: ABS is not affected by water, inorganic salts, alkali alcohols and hydrocarbon solvents and a variety of acids, but it is soluble in aldehydes and aldehydes. And chlorinated hydrocarbons will cause stress cracking when eroded by glacial acetic acid and vegetable oil. The appropriate PTFE content is 15% PTFE for non-crystalline and 20% PTFE for crystalline plastics. It is convenient to add engineering plastic base BS in a wide range of applications. In PA66 blended composite materials, different components are mainly combined by physical action. During melt extrusion, the macromolecular chain will be broken under strong shearing force, resulting in a certain amount Therefore, block or graft copolymers can be generated, and solvents can be filled in the mixture, and chemical bonds can also be introduced.
