PURPOSE: To obtain a rubber molding not causing sticking even by carrying out long-term contact or pressure contact of a rubber molding used in direct contact with a metal surface of a seal material molded by a rubber, e.g. gasket, oil seal or O ring, a vibrating material made of a rubber or a rubber cushioning material such as rubber belt, etc., for railroad or further, a rubber belt for transmission or a rubber belt for conveyer and a rubber molding having effect capable of preventing sticking to such metal. CONSTITUTION: A rubber blend in an amount of 100 pts.wt. is blended with an olefinic hydrocarbon compound having 100-160 deg.C melting point in an amount of 3-20 pts.wt. and the blend is molded and the resultant rubber molding is valcanized and heated and then aged at a temperature not lower than a melting point of the olefinic hydrocarbon compound and thereby, the olefinic hydrocarbon compound is oozed, cooled and solidified and mold-releasing film is integrally formed. |
