TPR is thermoplastic rubber that has the melting and molding properties of plastic while still maintaining some of the flexible properties of rubber. Thermoplastic rubber differs from thermoplastic elastomer, or TPE, in that thermoplastic rubber has a shiny side when melted where the elastomer has a matte finish.
TPR rubber can be as soft as a gel-like material or almost as hard as molded plastic. Materials made from TPR, particularly those that are of a softer material, may become slightly sticky when exposed to high temperatures such as those over 30 to 40 degrees Celsius. The elasticity of TPR rubber is similar to that of cross-linked rubber.
