NEOFLON PFA AP-231SH is a high purity PFA with fully fluorinated. It is excellent in melt processability and stress crack resistance.  It is used for chemical supply tubing at semiconductor factories. 

Introduction 

- AP-231SH is a copolymer of tetrafluoroethylene and perfluoroalkylvinylether.  

- High purity PFA with terminal groups fully fluorinated. 

- Good melt flowability while maintaining excellent properties of PTFE. It can be melt-molded as a  thermoplastic resin by extrusion molding. 

- Suitable for extrusion molding and transfer molding. It is used for tubes, sheets and valve lining  applications. 

- Less fluoride ions due to the fluorinated terminal group. 

- It is a PFA with the best stress crack resistance. 

- 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 ℃. 

- Excellent weather resistance. No properties change even when exposed outside for a long time.

- Non-stickiness. It shows excellent releasability and water repellency / oil repellency.
