Cork Rubber Sheet
Model:KXT B602
Kaxite Cork rubber sheet is made by using granulated cork and synthetic rubber polymer and their assistants. The cork mixed material such as neoprene and nitrile, silicone, vitone, etc. Please contact with us to help you with your cork rubber sheet needs.
KXT B602 Cork Rubber Sheets are manufactured from high-quality cork granules bonded with synthetic rubber polymers (NBR, SBR, Neoprene, Silicone, etc.). They combine the compressibility and recovery of cork with the flexibility and durability of rubber. Excellent resistance to oils, fuels, gases, and many chemicals. Available in medium (55-70 Shore A) and hard (70-85 Shore A) grades. Sheet thickness from 1mm to 10mm, custom sizes available. Ideal for gasketing, expansion joints, vibration isolation, and sealing applications. Request a quote →
