PFA Characteristics: PFA is a fluoropolymer co-polymer of tetrafluoroethylene and perfluoroalkoxy monomer, known for:

Excellent mechanical strength

Outstanding dielectric properties

Chemical resistance to solvents and high temperatures (240°C to 260°C)

Processing PFA via Injection Molding requires precise heating and cooling control for optimal results, while our lining technique offers greater effectiveness and efficiency compared to conventional Transfer Molding Systems.
