NEOFLON™ PFA AP-230 PFA良好的柔韧性

NEOFLON PFA AP-221SH is fully fluorinated fluororesin with improved crack resistance while maintaining melt flowability.

Introduction

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 lining applications.

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.

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.
