PURPOSE:To reduce weight and to improve light-shielding performance, rigidity and heat-resistance by mixing crushed chaffs into thermoplastic resin material. CONSTITUTION:A meter housing for car is formed with complex resin material where thermoplastic resin is mixed with chaffs then added with organic or inorganic reformer as required. Consequently weight can be reduced while conventionally indispensable expensive titanium oxide is required scarcely resulting in cost reduction while since crushed chaffs are organic material having low thermal conduction, thermal shielding effect and noise-proof effect can be improved. |
