Overview

GORE STA-PURE PFL PTFE reinforced fluroelastomer tubing

STA-PURE PFL handles nearly all aggressive chemicals, including organic solvents such as methyl ethyl ketone, toluene and acetone.

STA-PURE PFL is a high-performance composite of expanded polytetrafluoroethylene (ePTFE) and a platinum-cured perfluoroelastomer, giving extraordinary chemical resistance, extremely long life and very high burst pressures. It is free from plasticisers, acid acceptors and other processing aids, making it one of the purest tubings available.

Leachability tests using ethyl acetate yielded over 100 times less total extractables than other fluoroelastomer tubing materials. In addition, STA-PURE PFL has Class VI tests for pharmaceutical applications.
