Bayer Desmopan 795U TPU德国拜耳报价相关介绍如下：

TPU耐紫外线TPU黄变无疑是zui令人头疼的事情,尤其是高透明或白色的制品.此系列中产品除具备良好的物性之外特别添加耐黄变之成分,其耐黄等级为4.5以上.确保在耐紫外线(黄变)要求高的产品中使用无后顾之忧，耐水解及耐腐蚀TPU具有高机械强度，同时具有改良的抗水解性和良好的低温柔韧性，在油、脂和溶剂中的溶涨性极小。该系列牌号常被应用于各种挤出制品及高应力要求的结构部件。改进了压缩变形率、弹性、耐热性、耐水解性、抗油脂性能、抗微生物性能等。这些注射牌号首先也是zui多地应用于汽车、机械工程以及工厂设备中的一些功能部件。

Bellows in Desmopan：

OEM:

DaimlerChrysler AG Stuttgart

Part design:

Flexible thermoplastic polyurethane sleeves are employed to protect articulations, suspensions and gear racks in chassis and steering systems.

On the Mercedes Benz "S" class, the air springs (front and rear axle) have been covered by bellows in Desmopan?. These protect the springs from outside influences, such as dust, oil, grease and dirty water, and thus increase their functional reliability. At the same time, the covers also fulfil the thermal and mechanical requirements placed on buckling and wear resistance under high dynamic loads.

One of the prerequisites for the production of these large bellows (approx. 400 mm long) by extrusion blow molding is a high melt rigidity. The Desmopan? ester blow molding grades, 3485A and DP 3491A, are noted for their more rapid crystallization and improved morphology. The resulting improvement in melt rigidity permits longer tubes to be made, including spcial versions with areas of different wall thicknesses.
