Neoflon® PFA AP-221SH

全氟烷氧基

DAIKIN INDUSTRIES, Ltd.

 

产品说明:

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.
