-普通塑料材料在70℃以上的环境中容易长期氧化，TPU具有良好的抗氧化性-一般来说，TPU的耐温性高达120℃。

耐油性和耐化学性

TPU是一种极性聚合物材料，与非极性矿物油的亲和力很小。几乎用于未腐蚀的燃油（如煤油、汽油）和机械油（如液压油、机油、润滑油等）

在TPU产品中，聚酯系列产品具有更好的耐油性；TPU薄膜和片材的油脂体积变化不大，拉伸强度甚至高于初始值；应注意的是，矿物油

如果薄膜中有少量水分，则会对薄膜的物理性能产生不同程度的负面影响

低温性能

TPU具有非常好的耐低温性能，通常高达-50°C，可以在不能进行低温脆化的各个领域取代普通PVC。它特别适用于寒冷地区的相关产品

气密性

TPU非常容易使用高频或热压进行焊接，因此广泛应用于充气产品中。气体系数是指在恒定温度和压力下，气体通过样品指定区域的速率

同一种材料对不同气体的渗透性有时是非常不同的。一般来说，聚酯系列产品的气密性优于聚醚系列产品

生物医学性能

TPU具有生物相容性、无毒性、无过敏性、无局部刺激性、无热原性等特点，广泛应用于医疗、健康等相关产品以及运动和防护装备中

Tpu Low Temperature Resistance And High Flexibility

Product Details

tpu low temperature resistance and high flexibility

High temperature resistance and oxidation resistance

-Ordinary plastic materials are easy to oxidize in an environment above 70°C for a long time, and TPU has good oxidation resistance;-in general, TPU has a temperature resistance of up to 120°C.

Oil and chemical resistance

TPU is a highly polar polymer material that has very little affinity with non-polar mineral oil. It is almost used in fuel oil (such as kerosene, gasoline) and mechanical oil (such as hydraulic oil, engine oil, lubricating oil, etc.) Not corroded;

Among the TPU products, polyester series products have better oil resistance; TPU films and sheets have little change in the volume of grease, and the tensile strength is even higher than the original initial value; it should be noted that the mineral oil

If there is a small amount of moisture in the film, it will have varying degrees of negative effects on the physical properties of the film.

Low temperature performance

TPU has very good low temperature resistance, usually up to -50°C, and can replace general PVC in various fields where low temperature embrittlement cannot be applied. It is especially suitable for use in cold zone related products.

Air tightness

TPU is very easy to use high frequency or hot pressure to weld, so it is widely used in inflatable products. The gas coefficient refers to the rate of gas passing through the specified area of the sample at a constant temperature and pressure.

The permeability of the same material to different gases is sometimes very different. Generally speaking, the air tightness of polyester series products is better than that of polyether series.

Biomedical performance

TPU is biocompatible, non-toxic, non-allergenic, non-locally irritating, and non-pyrogenic, so it is widely used in medical, health and other related products as well as sports and protective equipment.
