Product Details
ePTFE (Expanded Polytetrafluoroethylene)
Expanded Polytetrafluoroethylene (ePTFE) is a highly versatile,
porous form of polytetrafluoroethylene (PTFE), a synthetic
fluoropolymer of tetrafluoroethylene, which is chemically inert and
widely known under brand names like Teflon. Unlike traditional
PTFE, ePTFE is produced through a specialized expansion process
that involves stretching PTFE under controlled conditions to create
a microporous, fibrous structure. This 3D network of interconnected
nodes and fibrils gives ePTFE unique physical and mechanical
properties, making it distinct from its solid PTFE counterpart.
Main Technical Indicators
