Bayer Desmopan 955U TPU德國拜耳報價相關(guān)介紹如下：

Pneumatic tubes out of Desmopan

Part design:

Desmopan? DP 1350D is a thermoplastic polyurethane with excellent extrudability that has been custom-formulated for the production of hoses. The melt solidifies very rapidly, resulting in hoses with high dimensional stability. Tight wall thickness and diameter tolerances can also be maintained. The ester-based TPU is highly transparent, making it easy to keep a visual check on the media being conveyed.
And because Desmopan? is easy to color, hoses can be produced in a wide range of different colors. The product has a hardness of 50 Shore D and withstands the required bursting pressures, which can be more than 25 bar, depending on the diameter of the hose.

In addition to properties such as high flexibility, long-term folding resistance and low compression set, the material also boasts very good wear resistance and particularly high resistance to oils and a broad range of other chemicals.

The new material is an excellent candidate for applications such as fuel and lubricant hoses, pressure control systems and pipelines for transporting chemicals.

TPU材料在使用過程中經(jīng)常受摩擦、刮磨、研挫等機(jī)械作用，會引起其表面逐步磨損，因此材料的選擇磨耗性顯得非常重要。TPU塑膠原料耐磨性能優(yōu)異，較天然橡膠耐磨五倍以上，是耐磨制品*的材料之一彈性體在應(yīng)用時由于產(chǎn)生裂口擴(kuò)大而使之破壞稱為撕裂，撕裂強度就是材料抵抗撕裂作用的能力;一般而言TPU具有較高的抗撕裂能力，撕裂強度與一些常用的橡塑膠比較是非常優(yōu)異的TPU在渾濁下耐水性能是良好的，1～2年內(nèi)不會發(fā)生明顯水解，尤其以聚醚系列更佳。聚酯系列在50℃的水中浸泡半年或70℃浸泡3周或100℃浸泡3～4天，會*分解，這是TPU適合作為環(huán)保材料的原因之一，需經(jīng)常性與水接觸之產(chǎn)品，則建議使用聚醚系列。
