Summary: TPU film, a thermoplastic TPU elastomer, is made by extrusion mixing of MDI with NCO functional groups, POLYOL with OH functional groups, and 1.4BG. Due to its good elasticity, excellent physical properties, and various good mechanical strengths, it is widely used in processing methods such as injection molding, extrusion, calendering, and dissolving into solution-type resins. It is a commonly used plastic material in the plastics processing industry, and its products cover a wide range of industrial applications and civilian necessities.

The characteristics of TPU film are mainly reflected in the following ten aspects:

1. Hardness

The higher the hardness level of the TPU film, the higher the puncture resistance and wear resistance of the product. With a low hardness level, the product exhibits a very smooth texture and a very soft feel.

2. Abrasion Resistance

The abrasion resistance of TPU film surpasses many other common polymers. It is more than five times more wear-resistant than natural rubber and is one of the preferred materials for wear-resistant products.

3. Tensile Properties

TPU film has a tensile strength as high as 70 MPa and an elongation at break of up to 800%. One of its most commendable properties is its tensile ability.

4. Weather Resistance

TPU film has better weather resistance than natural rubber and other synthetic rubbers.

5. Low-Temperature Flexibility

TPU film has excellent low-temperature flexibility. Even when exposed to temperatures as low as -30 degrees Celsius, most films maintain flexibility, making it an ideal material for harsh environments. (TPU crosslinking agent, crosslinking agent manufacturer, PVC adhesion promoter)

6. Temperature Resistance

TPU film has a temperature resistance of up to 130 degrees Celsius, and the polyether series has a temperature resistance of up to 90 degrees Celsius.

7. Oil and Chemical Resistance

PU is a strong polar polymer material with little affinity for non-polar mineral oils and is almost unaffected by fuel oil and machine oil. Among TPU products, the polyester series has better oil resistance.

8. Biomedical Properties

TPU film has excellent biocompatibility, is non-toxic, non-allergenic, non-irritating, and non-pyrogenic, so it is widely used in medical, hygiene, and related products, as well as sports and protective equipment.

9. Environmentally Friendly and Biodegradable

TPU film does not produce air pollution when burned and can biodegrade in soil within 3-5 years. According to Coating Online, the polyester series will completely hydrolyze after soaking in water at 50 degrees Celsius for half a year, or at 70 degrees Celsius for 3 weeks, or at 100 degrees Celsius for 3-4 days.

10. Wide Range of Applications

TPU film can be vacuum or heat processed while retaining its flexibility and performance. This material can also be welded into irregular shapes.

TPU film has been widely used in: footwear, clothing, inflatable toys, water and underwater sports equipment, medical equipment, fitness equipment, car seat materials, umbrellas, suitcases, bags, etc. (TPU crosslinking agent, crosslinking agent manufacturer, PVC adhesion promoter)
