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.
