NEOFLON PFA AP-211SH is a fully fluorinated high purity PFA. Melt flowability and stress crack resistance are excellent. It is suitable for injection molded parts used for semiconductors.
Introduction
- AP-211SH is a copolymer of tetrafluoroethylene and perfluoro alkyl vinyl ether. At the same time, it is a high purity PFA with its end groups completely fluorinated.
- Good melt flowability while maintaining excellent properties of PTFE. It can be used for melt molding as a thermoplastic resin. Injection molding and extrusion molding are suitable.
- Excellent in melt flowability. Applicable for injection molded products. It has been used for injection molded parts for semiconductors such as fitting nuts.
- Less eluted fluoride ions. Due to the fluorinated terminal group.
- The most excellent stress crack resistance in injection molding grade of PFA.
- Excellent chemical resistance which is not affected by most of the chemicals.
- Flexible and tough under the cryogenic to high temperature. - Excellent heat resistance. Continuous use temperature is 260 ℃.
- Nonflammable like POLYFLON PTFE and NEOFLON FEP.
- Excellent weather resistance. No properties change even when exposed outside for a long time.
