do you know that tpu film is also called polyurethane film?

tpu film：TPUalso known as polyurethane. therefore, tpu film is also called polyurethane film. it is a type of block polymer. tpu film contains pu without cross-links contains hard and soft segments made of polyether or polyester (soft segments) or polycaprolactone

1. excellent wear resistance: the wear value of tpu film is 0.35-0.5mg, which is the smallest among plastics. adding lubricating fluid can reduce friction, thus further improving wear resistance;

2. tensile strength and stretch rate: tensile strength of tpu filmthe strength is 2-3 times that of pure natural rubber and artificial rubber. the tensile strength of polyester tpu is >60mpa, and the elongation is 410%. the tensile strength of polyurethane tpu is 50mpa, and the elongation is 550%;

3. oil resistance: the oil resistance of tpu film is better than that of nitrile rubber, and it has a good oil resistance service life;

4. cold resistance, weather resistance, and ozone resistance. the weather embrittlement resistance of tpu film is stronger than that of natural rubber and other artificial rubbers. its ozone resistance and radiation resistance have unique uses in the aviation industry. ;

5. food medical grade: tpu film has biocompatibility and anticoagulant function, and the use of medical tpu film is becoming more and more common. such as blood transfusion tubes, drip tubes, and liquid delivery tubes. tpu film does not contain reinforcing agents, is odorless and non-toxic, and is mainly used in various food industries;

6. hardness usage range: the hardness of tpu film is 60a-75d. it still maintains its ductility when the hardness is above 85a, which is an advantage that some other elastomers do not have. therefore, the tpu film has high load support function and excellent suction and discharge effects;

7. tpu films are usually divided into polyester tpu films, polyether tpu and polyester and polycaprolactone tpu films.

tpu film is not only a high-pressure-resistant and aging-resistant material, but also an environmentally friendly material that is very suitable for the needs of contemporary customers.

it can be used in brand decorations such as shoe soles, shoe uppers, fitness equipment, car seat materials, umbrellas, luggage packaging, air bags, air cushions, etc.
