The PTFE Story

One remarkably versatile polymer, polytetrafluoroethylene (PTFE), lies at the heart of Gore's innovative products.

Bob Gore, now the chairman of the company's board of directors, discovered that rapidly stretching PTFE under the right conditions created a very strong, microporous material. The result, known as GORE™ expanded PTFE (ePTFE), exhibits an amazing array of properties:

Strength (high strength-to-weight ratio)
Chemical inertness
Biocompatibility
High thermal resistance
High chemical resistance in harsh environments
Low flammability
Low coefficient of friction
Low dielectric constant
Low water adsorption
Good weathering properties

Gore is the world leader in understanding and engineering PTFE, expanded PTFE, and PTFE composites into thousands of varied products.
