CR sponge is often processed into packing, and we have it in stock. The stock for C-4305 is available in thicknesses of 1 to 5 mm.
C-4305 is a foam material primarily composed of CR rubber, used for cushioning and water-stopping materials, and it does not allow liquids to pass through due to its closed-cell structure. It has almost no water absorption or breathability, and can achieve water-stopping with low compression rates. It complies with the flame retardant standard UL94HF-1. The hardness is a medium hardness of 25±5°, the color is black, the apparent density is 190±3 kg/m³, and the effective dimensions are 30mm × 1,000mm × 1,000mm (1,300mm, 2,000mm).
