In the field of automobile manufacturing, TPU polyurethane is required for all components of automobile, so there is a great demand for TPU polyurethane in the market, and TPU polyurethane can reduce the weight of automobile body and make the performance of automobile more superior. What is the importance of TPU materials for vehicle lightweight?
Among all plastics used in modern vehicles, TPU polyurethane is not only the largest in consumption, but also unparalleled in its application range: from the trunk to external parts, from soft to hard, from light to dense, to high-strength glass fiber reinforced products, the application of polyurethane can be seen everywhere.
Polyurethane hard foam, semi-hard foam, soft foam, self skinning, polyurethane elastomer, adhesive, polyurethane coating, synthetic leather, waterborne polyurethane and other products are used in the fields of automotive seats, cushions, headrests, floor mats, instrument panels, sun visors, door panels, ceiling linings and other interior trim parts, as well as automotive coatings, skylights, tires, sound and noise insulation materials, sealing materials and other fields.
The demand for automotive products is mainly determined by the sales volume. According to the sales volume data released by the automobile industry association, China's automobile sales reached 23.4919 million in 2014, a year-on-year increase of 6.86%. Although the global automobile sales volume keeps a slow growth, the world automobile sales volume will still grow at a rate of 2% ~ 3% in the next few years.
At present, the average plastic consumption of cars in technologically developed countries is 120kg / car, and the average plastic consumption of cars in Germany is 300kg. The average plastic consumption of cars in China is 80 ~ 100kg / vehicle, and that of Audi A2 is 220kg. By 2020, the average plastic consumption of cars in technologically developed countries will reach more than 500kg / vehicle. BASF has built an all Pu sports car with a top speed of 270km / h. RRIM technology is adopted. The Pu body is a carbon fiber reinforced microporous PU elastomer composite.
At present, the plastic parts used in cars are mainly PP (polypropylene), PVC (polyvinyl chloride), PU and PA (nylon). The development direction of automotive plastic parts is to continuously introduce cost-effective and recyclable materials.
Thermoplastic polyurethane elastomer (TPU) material can play its unique advantages. TPU has been used in various components of automobile body, including TPU plastic alloy. For example, TPU and PP, PVC, PA and other plastics form a cost-effective composite material, which can play an important role in the automobile industry. TPU rubber composite: the composite composed of TPU and a variety of rubber has important applications in the automotive industry.
