Bentonite clay acts as a reinforcing filler, rheology modifier, and processing aid in the rubber industry, enhancing mechanical properties like tensile strength, hardness, and wear resistance while reducing production costs. Modified organobentonite is used to improve gas barrier properties, corrosion resistance, and, when used in sulfur-bentonite form, to provide controlled release for efficient curing.
Bentonite clay rubber (often called bentonite waterstop) is a, flexible, water-activated sealing material composed of bentonite clay and rubber polymers, designed to expand up to 4-5 times its volume to create a waterproof barrier in concrete construction joints. It is used for waterproofing basements, tunnels, subway joints, sewage treatment plants, and water containment structures.
