a brief analysis of the high temperature resistance of tpu film

usually considered traditionalTPUit is heat-resistant to 80°c, which means that its long-term use temperature cannot exceed 80°c, otherwise the service life will be greatly shortened. there are also heat-resistant tpus that are said to withstand temperatures up to 130°c. there are also glass fiber modified tpus, which have high heat resistance temperatures.

tpu filmis a material containing -nh-coo- groups in the molecule. the long-chain diol and isocyanate components make up the soft segment, while the short-bonded diol and isocyanate components make up the hard segment. many properties of tpu depend on long chains of both types. the type of alcohol, its hardness is adjusted by the proportion of hard segments, and the photoaging properties of tpu elastic belts can be improved by adding light stabilizers.

it is plastic after all. the general heat resistance is about 100℃, but if you need to work in a high temperature environment for a long time, you need special materials. reinforced polyurethane has special high temperature and oil resistance and is often used in automobile oil cups and so on.

generally speaking, if heat resistance is required, dimensional measurements are required. the softening point of the card can be tested according to relevant standards. the overall softening point is used to test the softening point of asphalt pavement. it is commonly used in tpu hot melt adhesive. the data measured by the capillary rheometer seems to have 4 values. the detection principle is only to test the state of tpu under constant pressure when the softening point and pour point are the characteristics. thermodynamic properties of tpu.

1. tpu film:

tpu filmit has the characteristics of high strength, wear resistance, environmental protection, and easy processing; it is suitable for lamination, hot pressing, high frequency and other processing and molding methods. our film: the thickness is usually between 0.015mm-5.0mm, and the width is usually between 80cm-160cm; the thickness, width, color, surface effect and texture can be adjusted according to the different needs of customers. according to the special needs of customers, the physical properties of tpu films have been directionally improved; our films are widely used in shoes, bags, clothing, medical equipment, trademarks, toys, gifts, military supplies and other fields.

2. tpu composite cloth and tpu mesh cloth

composite fabric products focus on the combination of various fabrics and tpu membranes, especially for marine aviation manufacturers, military supplies, and medical care product manufacturers; the fabrics are rigorously tested before leaving the factory, and their excellent performance ensures that the products can be used in safe and durable for use in special environments.
