Expanded PTFE (ePTFE)
Expanded PTFE is a microporous PTFE material produced through controlled stretching and expansion. Golden Collar supplies ePTFE hollow-fiber and filter tubing for liquid, gas and corrosion-resistant filtration applications.
Discuss Your ApplicationExpanded PTFE Overview
Expanded PTFE (ePTFE) is made from PTFE through mechanical stretching and expansion to form a microporous structure. This structure supports filtration and fluid-handling applications while retaining the corrosion resistance and broad temperature capability associated with PTFE.
Golden Collar's internal product data identifies ePTFE hollow-fiber / filter tubing as a white microporous material for liquid, gas and corrosion-resistant filtration applications.
ePTFE Capability
Golden Collar supports ePTFE hollow-fiber and filter tubing for application-specific dimensions, roll supply and custom cutting requirements.
Microporous Structure
Mechanical stretching and expansion create the porous structure identified in Golden Collar's ePTFE tubing product data.
Liquid & Gas Filtration
Product documentation identifies applications involving water, purified water, chemical gas and other filtration media.
Custom Cutting
Standard packaging is 100 meters per roll, with cutting available according to customer requirements.
Multiple Tube Sizes
Hollow-fiber / filter tubing is available in a range of inner and outer diameter combinations from small tubing to larger diameters.
