K-Cell Semi-Closed Cell Foam Washers

CB Frost are an established UK manufacturer of sponge, foam, and rubber washers.

The materials we covert from sheeting to Washer are either closed cell, open cell, semi-closed cell sponge, foam, or solid rubbers.

Washers can be produced in a variety of manufacturing processes including Die Cut, Water Jet Cut and Kiss cut supplied on continuous rolls.

Washers are packed securely into suitable packaging and labelled in accordance with our customer requirements. Additional packing options such as barcoding, individual polybag, and cardboard separation are also available.

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.

K-Cell™ Semi-Closed Cell foam is a versatile material which is formed with semi closed cells, thus making it an excellent choice for applications where recovery from compression is required time and time again.

Adhesive Backed K-Cell Semi-Closed Cell Foam Washers

CB Frost can apply a pressure sensitive adhesive to either one or both faces of K-Cell™ Semi-Closed Cell 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 or Adhesive Backed K-Cell™ Super-Soft sponge washers is 7-10 days, however CB Frost are flexible and work with our customers to ensure we meet their expectations.
