| What is PFA PFA, also known as soluble polytetrafluoroethylene (soluble PTFE), PFA has similar properties to PTFE and FEP. PFA is produced in order to make up for the difficulty of PTFE processing, PFA processing can be divided into: injection molding, extrusion, molding. |
| PFA Features: 1 Crystallized material, small moisture absorption. It can be processed into products by the processing method of thermoplastics 2. Poor liquidity, easy to decompose. 3. Translucent particles, injection molding, extrusion molding. Molding temperature 350-400ºC |
| The difference between PTFE and PFA 1 Different performance PFA It is a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. The melt adhesion is enhanced, the viscosity of the solution is decreased, and the properties of the polytetrafluoroethylene have no change compared with that of polytetrafluoroethylene. The resin can be directly processed into products by ordinary thermoplastic forming methods. PTFE Polytetrafluoroethylene (F4,PTFE) has a series of excellent performance: high temperature resistance - long-term use temperature 200~260 degrees, low temperature resistance - still soft at -100 degrees; Corrosion resistance - resistant to and all organic solvents. Weather resistance - the best aging life of plastics; High lubrication - has the lowest coefficient of friction in plastics (0.04); Non-stickiness - having the smallest surface tension among solid materials without adhering to any substance; Non-toxic - has physiological inertia; Excellent electrical properties, is the ideal C class insulation material. 2. Different uses PFA PFA plastic is a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene copolymer. The melt adhesion is enhanced, the viscosity of the solution is decreased, and the properties of the polytetrafluoroethylene have no change compared with that of polytetrafluoroethylene. The resin can be directly processed into products by ordinary thermoplastic forming methods PTFE PTFE's unique properties make it widely used in industrial and Marine fields such as chemical, petroleum, textile, food, paper, medicine, electronics and machinery |
