What is PTFE?
Polytetrafluoroethylene (PTFE) is a fluorocarbon plastic; that is, a plastic in which the hydrogen normally found in association with carbon in organic materials has been replaced by fluorine. This produces a number of remarkable properties, and PTFE is reputedly the most inert substance known to man. It was discovered and developed by Dupont™, whose trade name is Teflon®.
PTFE can be used to produce eigher PTFE coated fiberglass fabrics,PTFE tapes or PTFE belts.
 
How is your coating?
Youngsun uses PTFE in the form of water-based (aqueous) dispersion to coat flexible woven, and some non-woven, materials such as glass fibre cloth (usually referred to as glass cloth, or simply “glass”),  Kevlar® and woven wire. These high performance substrates lend the polymer additional dimensional stability and mechanical strength. Only materials which stand the very high processing and application temperatures can be coated. A variety of techniques can be used in processing to improve the tear strength and resistance to creasing of the finished fabric, provide conductivity (anti-static properties), or resistance to oil and fats.
 
How wide are your PTFE coated fiberglass fabrics?
It all depends on the thickness of the coated fabric you require. You can buy the majority of our Youngsun fabrics from 50mm – 4000mm wide. Please call us to confirm availability.

What adhesive systems do you provide on your tapes?

How do I apply your tapes?
