PFA is a relatively new fluoroplastic in China. Its processing conditions are relatively strict, but its performance is excellent. It is mainly used in the chemical industry with high temperature resistance and high corrosion resistance and the fluoroplastic wire and cable industry.
Custom PFA teflon plastic injection mold molding in Teflon is a kind of Teflon fluorine resin. It is tetrafluoroethylene-perfluoroalkoxy vinyl ether copolymer, also known as soluble polytetrafluoroethylene, also known as perfluoroalkoxy resin. Now Miss Dankai Teflon Tube will take you to learn more about the performance and application of PFA:
1. What is: Custom PFA teflon plastic injection mold molding
PFA resins are relatively new melt-processable fluoroplastics.
The melting point of PFA is about 580F, and the density is 2.13-2.16g/cc (grams per cubic centimeter). PFA is similar to PTFE and FEP, but its mechanical properties are slightly better than FEP above 302T, and it can be used at temperatures up to 500F. Its chemical resistance is comparable to that of PTFE. The product forms of PFA include granular products for molding and extrusion, powder products for rotational molding and coatings; its semi-finished products include films, plates, rods and pipes. PFA resins distributed in the US market include Teflon brand from DUPOut Company, Neoflon brand from Daikin Company, Hthen brand from Ansimont Company, and Hostafl brand from HOechst Celanese Company. The use of PFA is similar to that of FEP.
2. PFA 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 PTFE. 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 corrosion resistance, corrosion resistance to all chemicals, lowest friction coefficient among plastics, and good electrical properties, its electrical insulation is not affected by temperature Impact, known as the "King of Plastics", V0 level of fire protection.
3). Its chemical resistance is similar to that of polytetrafluoroethylene and better than that of vinylidene fluoride.
4). Its creep resistance and compressive strength are better than PTFE, its tensile strength is high, and its elongation can reach 100-300%. Dankai has good dielectric properties and excellent radiation resistance. Great flame retardancy.
5). Non-toxic: It is physiologically inert and can be implanted into the human body.
3. Custom PFA teflon plastic injection mold moldingapplication:
1). It is suitable for making corrosion-resistant parts, wear-reducing and wear-resistant parts, sealing parts, insulating parts and medical equipment parts.
2). High-temperature wires, cable insulation, anti-corrosion equipment, sealing materials, pump valve bushings, and chemical containers. Molding performance 1. Crystallized material with low moisture absorption. It can be processed into products by the usual thermoplastic processing methods.
3). Poor fluidity, easy to decompose, and produce corrosive gas when decomposed. The molding temperature should be strictly controlled not to exceed 475 degrees, the mold should be heated to 150-200 degrees, and the resistance of the pouring system to the material flow should be small.
4). Translucent pellets, injection molding, extrusion molding. Molding temperature is 350-400 degrees, above 475 degrees is easy to cause discoloration or bubbles. And note that demoulding will be more difficult.
5). Because the molten material has a corrosive effect on the metal, the mold needs to be electroplated with chrome for long-term production.
The chemical properties of PFA, FEP, and PTFE are similar, but Dankai FEP can only be used below 200 degrees, and PTFE cannot be injected.
The company has a senior research and development team with international standards and a production line of fluoroplastic products imported from abroad. Some fluoroplastic products have passed ISO9001, SGS, and FDA certification.
