Some of the main features of TPU films

TPU films, also known as thermoplastic polyurethane elastomer films, are used in many industries due to their diverse properties and wide range of applications. Here are some of the main features of TPU films:

Tensile properties:

TPU films have high tensile strength, typically up to 70MPa, and elongation at break can be as high as 800%. This means that the TPU film is able to withstand large deformations without breaking.

Abrasion resistance:

TPU film is far more abrasion resistant than many other common polymer materials, such as being more than five times more abrasion resistant than natural rubber, making TPU an ideal material for making wear-resistant products.

Tear properties:

TPU film exhibits high tear resistance, and its tear strength is better than that of commonly used rubber and plastic materials.

Twist and turn performance:

TPU film retains good flex resistance under different environmental conditions, which makes it a good choice for making products that need to be bent or folded frequently.

Hydrolysis Resistance:

TPU film shows good hydrolysis resistance in a humid environment, and no obvious hydrolysis will occur even if it is soaked for a long time under certain conditions.

Hardness:

TPU films can be adjusted according to their hardness levels, with higher hardness products having better puncture resistance and abrasion resistance, while lower hardness products have a softer feel and better texture.

Weather Resistance:

TPU film has excellent weather aging resistance, which is better than natural rubber and other synthetic rubbers, and is suitable for outdoor long-term use.

Low Temperature Flexibility:

Even at very low temperatures, TPU films retain good flexibility and are suitable for use in cold environments.

Oil & Chemical Resistance:

TPU material has good resistance to non-polar mineral oil, is not easily affected by fuel oil and mechanical oil, and has strong chemical corrosion resistance.

Biomedical Performance:

TPU film has good biocompatibility, non-toxic, non-allergic reaction, no local irritation and no pyrogens, suitable for medical and hygiene products.

Eco-degradability:

TPU film does not produce harmful substances when burned, and can be biodegraded under specific conditions, making it an environmentally friendly material.

Processing characteristics:

TPU film can be made by a variety of processing methods, including blown film method, casting method, coating method and calendering method, etc., with strong adaptability and a wide range of applications.

To sum up, TPU film has found a wide range of applications in many fields due to its unique properties, including but not limited to footwear materials, ready-to-wear clothing, water sports equipment, medical equipment, etc.
