Glass fabrics for rubber adhesion

Market leaders in adhesion of glass fabrics to silicone

Glass fabrics for rubber adhesion – Compotex

Glass fabrics are excellent for high-temperature resistance. Their tensile and performance characteristics are unchanged at temperatures up to 500 C. Compared to other fibres, they have poor abrasion resistance. When coated with rubber, it is often for high-temperature applications that do not require dynamic flexibility.

Glass fabrics are therefore commonly used with rubber compounds that also perform well at high temperature. For many applications, this means silicone rubber, which is temperature resistant up to 300 C. (contrasting, for example, with natural rubber which is temperature resistant up to 80 C).

Compotex has been one of the first companies worldwide to develop water-based dipping technologies for the adhesion of glass fabrics to silicone rubber. With aerospace approvals, we offer trusted solutions for our customers.

The two main bonding technologies we use for glass are the Compotex PS system and the Momentive A174NT, both for adhesion to peroxide cured rubber.

Glass Fabrics for Rubber Adhesion Example

One of our customers asked us to help them decide whether they should use the Compotex PS system or the Momentive A174NT system for a new application.

Because both bonding technologies are in regular production at Compotex, we were able to quickly add two small rolls of customer fabric to scheduled production runs – one with our Compotex PS technology and the other with the Momentive A174NT bonding technology.

In this case we used just 5 metres of fabric in each trial, which is enough length on our advanced machinery for a production trial to specification.

Our customer had everything they needed from Compotex within 2 weeks, giving them extra time for their tests and product trials. That extra time meant that development wasn’t rushed, and better choices could be made by our customer on their production route. They were also able to spend more time perfecting the technical characteristics of the parts they were making.
