- Product Benefits
- AP 221SH is a copolymer of tetrafluoroethylene and perfluoroalkyl vinyl ether. It is 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. Transfer molding and extrusion molding are suitable.
- Excellent in stress crack resistance,
- Especially suitable for transfer molded products. It has been used for small size valve liningapplications.
- Less eluted fluoride ions. Due to the fluorinated terminal group.
- Excellent chemical resistance which is not affected by most of the chemicals.
- It retains flexibility without losing toughness under the environment from cryogenic to high temperature,
- Excellent heat resistance. Continuous use temperature is 260 °C°C.
- Low dielectric constant and dielectric loss tangent in a wide range of temperature and frequency.
- Nonflammable like Polyflon PTFE and Neoflon FEP.
- Excellent weather resistance. No properties change even when exposed outside for a long time.
