EPDM rubber is favoured for its excellent resistance to weathering. Its chemical stability means that there is special chemistry for the adhesion of textiles to EPDM rubber in the curing process.
Compotex uses water-based technologies for the adhesion of textiles to peroxide curing EPDM. An excellent bond is achieved, giving a strong dynamic performance.
We offer treatments for nylon, activated polyester, aramid and vectran to peroxide curing EPDM rubber.
For nylon and activated polyester, we utilise a two-stage process. For aramid and vectran there is an additional process. In all cases, the bond achieved to the peroxide curing EPDM is high.
For new developments, we undertake lab trials and small production trials for our customers. With production trials – we normally ask for about 20 metres of fabric – the customer will have enough fabric to go through their own calendering machine. Our fast development process means that our customers can test and approve new EPDM products quickly.

Compotex uses water based technologies for the adhesion of textiles to peroxide curing EPDM. An excellent bond is achieved, giving strong dynamic performance.
A textile company that we have worked with for many years asked us to partner with them and a rubber company on a new project for para-aramid reinforced EPDM rubber.
The first thing we needed to know was the curing system used with the EPDM. Once we understood that it was peroxide cured, we knew we had a solution.
We requested a length of the para-aramid fabric. The customer also asked us to do the adhesion lab testing with their peroxide curing EPDM rubber. Therefore, for the first lab tests, we did all the samples on the para-aramid and we cured and tested the adhesion on the samples.
We shared the results with our customer, and the project moved to the next stage.
We ran a production trial of 30 metres. The dipped fabric was then calendered by the customer, parts were made and the product testing and approvals followed.
