Steering wheel is used with the modified polypropylene thermoplastic elastomers made with polypropylene. Equipment selection an easy blend to promote industrialization, the twin-screw extruder, technology is simple, the material has high impact strength (according to GB 1043 Methods 25.5> 70Kg/cm) and low temperature brittle point (at ASTMD746 Method BT ≤-50C). The material is made by the domestic variety of professional factory steering wheel steering wheel, through the JB3979-85 Republic of China Machinery Industry Ministry ministerial standards, has entered the industrial production. It is currently the steering wheel of the good domestic manufacturing materials, the material particularly suitable for cold region application on the steering wheel.
