Natural gum rubber sheet has high tensile and elongation characteristics along with superior abrasion resistance. Also for applications requiring a soft rubber seal. Conforms to irregular flanges with bolt heads. Resists most organic salts, acids, alkalis, and ammonia. Non-marking gum rubber material has an excellent tear strength and is a resilient type of rubber that doesn't hold memory. Gum rubber also has a self healing ability making it ideal for shooting ranges. Gum Rubber is also abrasion resistant making it a good fit for sand blasting booths.
