CB Frost also offer the possibility of a door to door service providing our customers with the peace of mind that items will arrive safely, securely and in time.

CB Frost are the UK’s number 1 convertor of Rogers Corporation high performance BISCO® Silicones. Having a relationship spanning over 30 years, CB frost are streets ahead of the competition with regards to knowledge and availability of HT800 Silicone foam.

HT800 Silicone foam is a versatile, medium firmness silicone that offers the lightness of a foam with the enhanced sealing capabilities of traditional sponges. HT800 is commonly used to reduce shock and vibration, and provide protection (dust, moisture/water ingress) on a wide range of indoor and outdoor applications.


Tooling continues to be very important in the manufacture of die cut gaskets. Thanks to the company's long-standing history, we work with a variety of well-established tool makers in the West Midlands region.

Adhesive backed HT800 Silicone Foam Gaskets

CB Frost can apply a pressure sensitive adhesive to either one or both faces of HT800 Silicone foam. We stock a wide range of synthetic and acrylic tapes, our adhesive tapes come with an easy peel release liner which you simply remove to expose the adhesive. This face is then placed on to the substrate and firmly pressed to obtain the bond.


Our lead-time to supply plain HT800 Silicone foam gaskets is 7 working days. Adhesive backed HT800 Silicone foam gasket is 7-10 days, however CB Frost are flexible and work with our customers to ensure we meet their expectations.
