At NEDC, we die cut all sorts of products. One product that I’m surprised I have not mentioned in the 5 years I’ve been doing the blog, is PTFE Coated Fiberglass Fabric materials. Right before the turn of the New Year, I decided it may be a good idea to discuss a material that we not only sell, but actually use at NEDC. 

Why use PTFE, and Fiberglass Together?

PTFE is coated onto a fiberglass substrate. Since there is only two parts to this, I figure I’d break them down

PTFE- PTFE is used because its: Chemically Resistant, High Temperature Tolerant, Anti Stick, Low Friction Surface

Fiberglass- Fiberglass is used because it can withstand enormous pressures without flowing, its very tear resistant, and also high temperature

As we go through the properties below, you can start to see why these two materials combined together make such a great combination. Admittedly, these fabrics are some of the most versatile materials around. This is for a few reasons- which I’m sure I’m not capturing all their uses, but the point is- these materials are super versatile:

  1. They come in tape formats, which can be super helpful in situations where you need a good release consistently. Saint Gobain Performance Plastics (SGPP) puts out. These include:

SG13, SG56, CHR A2005, SG26, and SG15 

2. These materials can be provide in a porous fabric that allows excess trapped air, and other volatiles to escape out of an application during molding/shaping

3. Actually, we use PTFE coated fiberglass fabric here at NEDC when we are bonding things together often. The reason for this is it at has a high release quality, well also being able to withstand the high temperatures that are commonplace in bonding applications. For a second, just forget bonding applications – but baking, and cooking applications often utilize materials like this as well. 

4. These materials are oftentimes FDA compliant to the 21 CFR 17.1550- which is different then the 21 CFR 17.1660 we talked about in our FDA gaskets blog. 

Each material, or tape can have a different coating of PTFE (polytetrafluoroethylene) for different applications. Certain coatings of PTFE are better for higher temperature, or more release applications. 

More Information on PTFE coated Fiberglass Fabric 

NEDC die-cuts, and otherwise converts PTFE coated fabric into finished die-cut gaskets, and parts. These materials are typically on the lower gauge side. For more information on PTFE coated fiberglass fabric, please contact sales@nedc.com.
