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

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

Armaflex® ZH & ZH-C are the worlds first flexible closed cell halogen free insulation material to meet EN45545-2 fire protection requirements.

Along with Rail SD & SD-C it is the leading and most innovative closed cell thermal insulation available to the railway industry worldwide.

Armaflex® ZH comes in two grades; either standard ZH or ZH-C which is the standard ZH material but with a silver metallic look coating.

Adhesive Backed Armaflex Rail ZH & ZH-C Strip

CB Frost can apply a pressure sensitive adhesive to either one or both faces of Armaflex Rail ZH & ZH-C 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.
