Thermoplastic Polyurethane Film is also commonly referred to as TPU, Urethane or PU film. Thermal Plastic Urethane was first developed in 1937 and has for decades been used in the manufacture of a unique class of films. There are several properties that make TPU films preferable to common films such as PP, PE and PVC are.

　　TPU Film have simple molecular structure, TPU doesn't pollute the air while burning and incinerating and will be degraded naturally within 3~5 years under the action of humidity and microorganism after being buried in soil, so it is a good substitute of PVC products and a main-stream product for environmental production.

　　There are three main chemical classes of TPU films. These include Polyester, Polyether and Polycaprolactone. In addition polyurethane TPU films are available in aromatic or aliphatic varieties. Aromatic films are used in most consumer applications while aliphatic films are used in specialty applications that require high levels of optical clarity or specific adhesion properties.

　　Polyester TPU films are compatible with polar plastics such as PVC thus making them good choices for a wide variety of laminate. These films are commonly found in industrial aprons, conveyor belts, fabric laminates, geld pads and medical packaging. Among the excellent properties of Polyester TPU are:

　　Excellent fungal resistance

　　Excellent abrasion resistance

　　Excellent strength and durability

　　Excellent oil and chemical resistance

　　Polyether TPU films are the lowest specific gravity than Polyester or Polycaprolactone films and are more in a softer hand. These films are commonly used for a variety of applications such as medical mattresses, blood pressure cuffs, infusion bags, and surgical gowns. Among the benefits of Polyether TPU films are:

　　Excellent moisture resistance

　　Excellent fungal, microbial and body oil resistance

　　Excellent low temperature flexibility

　　Excellent UV stability

　  Polycaprolactone TPU films have the toughness of Polyester TPU films while also offering a higher level of low temperature flexibility and moisture resistance. These films are an excellent choice for hydraulic or pneumatic seals.

　　Advantages of TPU Film

　　Highly elastic, wear-resistant.

　　Safe and durable even in severe environment.

　　Good hydrolysis resistance and weather fastness.

　　Anti-yellowing, weather-proof, oil-resistant, acid-proof, warping-resistant. Anti-fungus, anti-biosis, anti-static, recyclable and degradable

　　No affected by oil, chlorine, sweat, cosmetic and seawater

　　Smoothly rounded edge keep your skin from irritation

　　No losing elasticity in cold or hot environment

　　Smooth surface is advantageous to screen printing

　　Environment friendly
