BF1000 silicone sponge

CB Frost are a UK preferred convertor of the BISCO range of silicone-based foams and have a relationship with Rogers Corporation extending over 30 years.

BF1000 is an extra-soft silicone sponge, offering the lightness of a foam, with the enhanced sealing capabilities of traditional sponges. It has a low compression set value, which means the material will return to 99% of its original thickness after being under compression, making BF1000 a good sealing material for several applications where shock and vibration is present or sealing against dust and moisture is required.

Available in stock in white and grey, rolls are generally 6mtrs long x 915mm wide in 1.6mm, 2.4mm, 3.2mm, 4.8mm, 6.4mm, 9.5mm, 12.7mm, 19.1mm and 25.4mm. CB Frost can supply BF1000 as rolls, or convert into strip/tape or die-cut shapes. For more information please contact one of our sales team, or visit the capabilities section of our website.
