Polyester fabrics for rubber adhesion

Specialists for the reinforcement of silicone rubber

Polyester fabrics for rubber adhesion – Compotex

Polyester fabrics are versatile and are widely used for rubber reinforcement for many different applications. We offer treatments for nearly all rubber compounds with a range of bonding technologies.

All Compotex processes are water based. Our versatile and adaptable production technology allows us to offer many excellent solutions to our customers.

For bonding of polyester to silicone rubber, we recommend either our Compotex PS system or silane chemistry – for example using the Momentive A174NT.

For adhesion to the sulphur curing rubbers – NR, SBR, Neoprene and Nitrile – it is most common to use activated polyester yarns, which are then RFL dipped and cured at a high temperature to give excellent adhesion. We have extended this technology to the peroxide curing rubbers, for example EPDM.

If ordinary polyester is used for reinforcing sulphur curing rubber, we use an additional process with Grilbond chemistry to activate the fabric before RFL dipping.

Polyester fabrics for rubber adhesion Example

We were asked to urgently sample a polyester fabric for commission dipping for adhesion to neoprene.

We immediately asked to check that the polyester used activated yarn which was suitable for a single stage RFL dipping process. The customer checked, and verified that it was.

We then asked how much fabric the customer had available for a production trial. It turned out that they only had 2 metres, which is a very small quantity for a production trial. However, in consideration of the speed that the customer wanted the development to be completed, we concluded that we could manage this small length with some extra planning.

We set aside some hours on one of our production machines to prepare the trial. We ran the trial extremely carefully, and everything went well. We were therefore able to ship the sample fabric on the next day and the customer was able to fast-track their testing and initial approvals.
