RUBBER MEMBER FOR PLASTIC DAMPER PULLEY HUB FOR CAR

摘要

PURPOSE: A rubber member for a plastic damper pulley hub for a car is provided to reduce noise and vibration and to increase durability and life of components by increasing thermal resistance and reducing a change of physical properties. CONSTITUTION: A rubber member for a plastic damper pulley hub for a car includes an AEM-based rubber or an EPDM-based rubber. The AEM-based rubber or the EPDM-based rubber, which is pressed rubber material, is pressed to a plastic hub having glass fiber of 30 to 60% by weight. The AEM-based rubber has an acryl content of 20 to 50% by weight and an ethylene content of 50 to 80% by weight. The EPDM-based rubber has an ethylene content of 10 to 70% by weight and a propylene content of 30 to 90% by weight.
