Shanghai Daoqin Plastics Co., Ltd.

         automotive light amount 化时代, material design formed is industry research important 课题, remove PP, PVC, PU, PA and other plastics a large amount of use outer, carbon fiber, glass fiber and other reinforcement material formed is automotive light amount 化时代 market research hot 点. thermoplastic property elastomer product technology development, its in automotive field/area application 越 越广泛. currently, automotive upper commonly used thermoplastic property elastomer has polyolefin type (TPO, TPV), polyester type (TPEE), polyurethane ester type (TPU), styrene type (TPS) and other.

        TPU wear resistance, resistant bending fatigue property, high elastic property 突出, can used for various automotive parts, used for 换档拉杆手柄, various 联轴节 轴 sleeve/set and gasket, various 线束 接插 parts, 螺旋伸 shrink electrical 线, cable jacket, belt/tape, toward 拉杆 护 sleeve/set and sheet/slice, 悬挂联 combined 铰链, liquid pressure gas 动, 悬挂隔 film, decrease film, decrease device, elastic 簧限位 fast and other, also can and other plastics or composite/compounding use, used for automotive 保险杠, safety gas 囊, anti and other parts.

         from full application scope 看, 欧美 区TPU product development relatively 早, technology relatively is formed 熟, in high field/area application more is 广泛, currently automotive upper application amount already ultra- 15%, 而亚太 区TPU product still application in low footwear materials is 主, automotive upper application also to 10%, China 区TPU in footwear materials field/area application ratio although has decrease small, automotive field/area application growth still 未达5%, and more use Imported or outer enterprise product is 主, can has very large development 空间.

        TPU in automotive field/area application can has below/following types 形式:

        (1)TPU/PP plastics alloy

        此 types material tool has light, property ratio excellent 良, can recycling and other advantages, can can used for automotive inner outer trim parts, 如保险杠 and its 支架, upper various and structure frame and other.

        (2)TPU/PC plastics alloy

        TPU and PC blending can improvement PC tough property, force cracking property, 断口敏感 property, resistant solvent agent, chemical resistant product property, meanwhile can reduce PC molding processing temperature degree, expand large its in automotive industrial application scope.

        (3)TPU/PVC plastics alloy

        TPU/PVC alloy can obvious improve/increase PVC elongation, and environmental protection property large large improve/increase, can decrease/reduce PVC in increase agent for ring for 人体造 formed 危害, from expand large PVC application areas.

        (4)TPU/PA6 plastics alloy

        TPU and PA6 blending not only TPU high elastic property, high strength, wear resistance, but also improves resistant temperature property, its comprehensive property can 突出, is types new type high property can composite/compounding material, in automotive industrial tool has application value.

        (5)TPU long fiber composite/compounding material

         long fiber reinforcement thermoplastic property composite/compounding material (LFT) tool has high strength, high rigidity, high dimensional stability, low warpage degree, use lifespan long, resistant creep and other excellent property can, in automotive industrial in already to application. its in TPU(alloy)/LFT composite/compounding material can used for automotive table/sheet 盘, 保险杠, sheet/plate, front and 车门组 parts, and 车身底部护 parts and other.

        综 upper 述, TPU in automotive field/area has multiple application 形式, its property can advantages 突出, formed is achieve automotive light amount important 途径, currently inner TPU industry development speed, new product launch, high application positive in expand large, versus its in automotive field/area application will large improves.
