Extrusions

CB Frost offer custom made extrusions from a range of polymers, each with a unique quality, and therefore suited for specific applications. Our extrusions are manufactured in both solid and sponge form in materials such as Silicone, Neoprene, EPDM, Nitrile and Viton, and can be supplied in coil form, cut to length or even fabricated/bonded to form gaskets.

Extruded Gaskets

Producing bonded extruded gaskets is a complex process. We can supply seals with either a hot splicing or vulcanised joint. These are techniques that use heat, pressure and film splice or uncured rubber to join the ends of profiles.

Extruded Vulcanised Seals

Vulcanised joining is a reliable, cost-effective process for joining sponge or rubber profiles. Applications include O-rings, tubing, rectangle/square profiles and is best suited for low volume quantities rather than high volumes.

Extruded Hot Spliced Seals

Hot splicing uses thin film and either a conventional heat source or infrared (IR) light to produce a sound bonded seal.

We can provide seals that are flame retardant, chemical resistant, Military grade, FDA and to British Standards – e.g. Natural rubber to BS1154, Neoprene rubber to BS2752 and Nitrile rubber to BS2751. They offer enhanced characteristics and require a minimum level of polymer content and regular batch testing.
