What is the difference between PTFE and expanded PTFE?

PTFE stands for Polytetrafluoroethylene. It is a synthetic fluoropolymer of tetrafluoroethylene. Expanded PTFE is made of 100% pure PTFE which can be used as a sealing agent. It is lightweight but strong.

How do you do expanded PTFE?

Expanded PTFE grafts are made by extrusion of PTFE resin mixed with a lubricant. The microporous structure of ePTFE is obtained by a process that involves rapid stretching of the extruded tube at high temperature.

What does ePTFE stand for?

What is sintered PTFE?

A: Sintered PTFE is a membrane featuring an open-celled, omnidirectional 3D-pore structure that is design-flexible and can be tailored in thickness, porosity, and volume to individual device needs.

What does expanded PTFE mean?

What is ePTFE? Expanded PTFE (ePTFE) tube is microporous so air-permeable, and is perfect for any applications that require a permeable material. As such, ePTFE is different to conventional PTFE. The material is soft and flexible, and feels somewhat like smooth, spongey marshmallow to the touch.

Can you bend PTFE?

Common Applications PTFE can be used in a variety of industries, and for various applications. It can be welded or bent to fit a particular space or shape.

Is ePTFE the same as PTFE?

We all know PTFE, the grandfather of fluoroplastics, but what is expanded PTFE? Also known as ePTFE, expanded PTFE is the microporous version of PTFE. ePTFE enjoys similar properties to PTFE and is perfect for any applications that require a permeable PTFE material.

What is ePTFE gasket?

EPTFE (Expanded PTFE) is a Universal sheet EPTFE Gasket material for most services. Gaskets cut from this Seal rough and irregular surfaces. Made from biaxial oriented expanded PTFE sheeting that is laminated to the required thickness.

What is unsintered PTFE tape?

Standard unsintered PTFE tape can be applied as a protective jacket for aircraft wiring and for example in cables in floor heating. In this application, the unsintered PTFE tape is wrapped around the cable which is then sintered at a high temperature by means of infrared or a salt bath.
