One of the commonly used precision injection molding materials: PFA
Release time:
Sep 19,2023
What is PFA? PFA is a minor copolymer of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. As a common precision injection molding material, PFA can be directly processed into products using common thermoplastic molding methods. Suitable for manufacturing corrosion-resistant components.
What is PFA?
PFA is a minor copolymer of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. PFAoftenWith precision injection molding materialsIt can be processed directly into products using conventional thermoplastic molding methods. Suitable for manufacturing corrosion-resistant components.
What is the nature of PFA as a commonly used precision injection molding material?
PFA has similar properties to FEP, but because its melt viscosity is lower than PTFE, it can be used at working temperatures up to 260°C while maintaining melt processability.
PFA has the following characteristics:
1) Very high operating temperature up to 260°C
2) Very low operating temperature of -200°C
3) Non-stick characteristics
4) Low friction surface
5) Very high resistance to chemicals and solvents
6) Very high resistance
7) Biocompatibility
What are the advantages and disadvantages of PFA as a commonly used precision injection molding material?
In addition to the unique properties of fluoropolymers, PFA also has the following advantages:
1) Continuous working temperature of 260°C-except for PTFE, the working temperature of PFA is the highest among all fluoroplastics
2) Welding and reshaping potential
3) Protection against harsh environmental conditions
4) Insulate from electricity, heat, chemicals and solvents
5) Good resistance to penetration
6) High purity grade available
7) High Definition
PFA has similar physical and chemical properties to PTFE, but its flexural life is 10 times that of PTFE, and its permeability is lower. PFA has excellent crack and stress resistance and a low coefficient of friction.
