Vectran fabrics for rubber adhesion

We offer fast and comprehensive lab and small production development for customers wanting to try out using vectran fabrics for new projects. Customers can quickly evaluate how vectran compares to aramid and nylon fabric in rubber parts.

We have developed proven bonding technology for vectran to rubber. Vectran is mostly used with the sulphur curing rubbers, Natural Rubber, SBR, Neoprene and Nitrile.

Our dipping process is water-based. In our production process, the vectran is first primed to activate the fibres, and the second dip is RFL to provide the adhesion to the rubber on curing.

The high-performance vectran fibre has very high tensile strength. Compared to para-aramid, it has higher abrasion resistance and is more resistant to flex fatigue. For these reasons, vectran is used to reinforce rubber when the finished part needs high strength and very high durability under dynamic stress. The rubber coating also protects the vectran from UV degradation.

Vectran fabrics for rubber adhesion Example

For many years, a customer had a product that was failing after a few years in use. This was because the fabric reinforcement was nylon and it didn’t have the necessary toughness and durability to survive over a long period of time.

We considered the fabric options: a different nylon specification, para-aramid or vectran. We chose a vectran fabric for its high abrasion resistance. We were asked to dip the fabric for adhesion to natural rubber.

We offered a choice of two dip options to the customer. These were quickly done in the lab and supplied for testing with the customer’s rubber compound. Both results were good, with one 15 – 20% better than the other. We, therefore, specified the better option.

The next step was a full production trial, in this case over 100 metres. The trial ran well, the fabric was coated with rubber and the fabric put into a field trial to establish its lifetime durability against the existing nylon fabric.
