FEP Tubing, Radiation Resistance

ONLINE INQUIRY
Catalog Number ACMA00038483
Description Radiation Resistance (MRad):10;
FEP, fluorinated ethylene propylene, is a melt processable fluoropolymer that allows for long, continuous lengths and has several distinct advantages over PTFE. Applications where FEP tubing is usually chosen require more optical clarity and flexibility. In heat shrinkable form, FEP has a lower recovery temperature than PTFE. This fluoropolymer makes heat shrink and convoluted products that meet 23053/11 and 81914 Mil Spec certifications, respectively. The material has low gas and permeability properties; possesses an excellent UV transmission rating; Biocompatible -USP Class VI approved; and is Gamma sterilizable.
