22-5900 / 5 Lb / Silicone Molding Rubber Strips

When liquid rubbers are shipped in cold weather they may become thick and difficult to use. The rubber may remain cold long after it has been placed in a warm room. Due to extreme temperatures rubber products may freeze. The rubber is not defective but needs to  be warmed by a heating pad or some other source of indirect heat. Optimal temperatures for warming the rubber would be between 100 and 150 degrees F or heat that is comfortable to the touch. Heat Cured/vulcanizing rubbers should respond within a few hours.
