LERG offers novolak resins for use in the tire and rubber industry, where, in a system with a curing agent, they are made into reinforcing components. When added to the raw rubber mixture, they enter into reactions with each other, and not with the rubber, to yield a resite network that penetrates the rubber during vulcanization. They are traded in the form of drops or flakes. We also offer phenolic resins in water solutions, which are used as a component in impregnating baths for polyamine and polyester fabrics in the production of conveyor belts, V-belts and other textile-rubber products.
