TPU film: TPU, also known as polyurethane. Therefore, TPU film is also known as polyurethane film or polyether film, which is a block polymer. TPU film includes TPU made of polyether or polyester (soft chain segment) or polycaprolactone, without cross-linking.
This type of film has excellent properties such as softness, wear resistance, and chemical resistance, and is widely used in various fields. In the packaging industry, TPU film is commonly used in food packaging to protect food from external pollution; In the medical field, it can also be used for packaging medical devices to ensure product hygiene and safety. In short, the characteristics of TPU film make it an indispensable material in many industries.
1. Excellent wear resistance: The wear value of TPU film is 0.35-0.5mg, which is a relatively small plastic. Adding lubricant can reduce friction and further improve wear resistance;
2. Tensile strength and tensile strength: The tensile strength of TPU film is 2-3 times that of pure natural rubber and synthetic rubber. The tensile strength of polyester TPU is greater than that of polyurethane TPU, which has a tensile strength of 60Mpa, elongation of 410%, and elongation of 550%.;
3. Oil resistance: TPU film has better oil resistance than nitrile rubber and has good oil resistance;
4. TPU film has stronger cold resistance, weather resistance, and ozone resistance than pure natural rubber and other synthetic rubber. Its advantages of ozone resistance and radiation resistance have unique main applications in the aviation industry.
5. Food and medical grade: TPU film has biocompatibility and anticoagulant function, and is increasingly used in medical TPU films. Such as blood vessels, droppers, and liquid delivery tubes. TPU film does not contain reinforcing agents, has no odor or toxicity, and is mainly used in various food industries;
6. Hardness application range: The hardness of TPU film is 60A-75D. TPU film has high load support function and excellent suction and discharge function, so it still has ductility when the hardness exceeds 85A, which is not available in other elastomers.
7. Normally, TPU films are divided into polyester TPU films, polyether TPU films, and polyethylene TPU films.
TPU film is not only a material that is resistant to high pressure and aging, but also an environmentally friendly material that is very suitable for contemporary customer needs. Can be used to decorate shoe soles, uppers, fitness equipment, car seat materials, umbrellas, bags, airbags, air cushions, and other brands.
