Bayer Desmopan 795U TPU德國拜耳報價相關介紹如下：

TPU耐紫外線TPU黃變無疑是zui令人頭疼的事情,尤其是高透明或白色的制品.此系列中產品除具備良好的物性之外特別添加耐黃變之成分,其耐黃等級為4.5以上.確保在耐紫外線(黃變)要求高的產品中使用無后顧之憂，耐水解及耐腐蝕TPU具有高機械強度，同時具有改良的抗水解性和良好的低溫柔韌性，在油、脂和溶劑中的溶漲性極小。該系列牌號常被應用于各種擠出制品及高應力要求的結構部件。改進了壓縮變形率、彈性、耐熱性、耐水解性、抗油脂性能、抗微生物性能等。這些注射牌號首先也是zui多地應用于汽車、機械工程以及工廠設備中的一些功能部件。

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.
