What material is TPU film?

Date:2024-03-30

TPU (Thermoplasticpolyurethanes), hot plasticity TPU elastomer, by including NCO functionality, MDI and OH functionality, POLYOL, 1.4 BG, made by mixing and extruding, with good elasticity, good physical properties, and a variety of mechanical strength is very good, therefore, Widely used in injection, extrusion, calendering and dissolving into solution resin processing methods, is a plastic material often used by plastic processing companies, and its products cover the range of industrial applications and civil necessities.

In recent years, due to the continuous development of new products, the amount of thermoplastic PU elastomer is continuing to increase, creating a new opportunity for the plastic processing industry with low cost and high added value. TPU (thermoplastic polyurethane) is increasingly popular because of its superior performance and environmental protection concept. At present, wherever PVC is used, TPU can become a substitute for PVC. But TPU has the advantages that PVC can't match.

TPU not only has superior characteristics of high tension, high tension, toughness and aging resistance, but also is a mature environmental protection material. At present, TPU has been widely used in: footwear, clothing, inflatable toys, water and underwater sports equipment, fitness equipment, car seat materials, umbrellas, suitcases, bags and so on.

The main features of TPU are:

1. A wide range of hardness: by changing the ratio of each reaction component of TPU, products with different hardness can be obtained, and with the increase of hardness, the products still maintain good elasticity and wear resistance. High mechanical strength: TPU products have outstanding bearing capacity, impact resistance and shock absorption performance.

2. Outstanding cold resistance: The glass transition temperature of TPU is relatively low, and it still maintains good elasticity, flexibility and other physical properties at minus 35 degrees.

3. Good processing performance: TPU can be processed by common processing methods of thermoplastic materials, such as injection molding, extrusion, calendering and so on. At the same time, TPU and some polymer materials can be processed together to obtain complementary polymer alloys. Resistant to oil, water and mold.




Use of various TPU molding products:

1. Auto parts ball coupling; Dust cover; Pedal brake; Door lock firing pin; Bushing plate spring bushing; Bearings; Shock-proof components; Interior and exterior decorative parts; Anti-skid chains and other mechanical and industrial components

2. Various gears; Seals (mainly wear and oil resistance); Shock-proof components; Drawing needle; Bushing; Bearing cover; Connector; Rubber screen; Printing roller and other clothing accessories women bra straps, clothing elastic, etc.

3. Shoes softball shoes, baseball shoes, golf shoes, football shoes sole and shoe front heel of women's shoes; Ski boots; Safety boots and other self-aligning wheels;

4. Handle; Watchband and other pipes, hose high-pressure pipe; Oil pressure pipe; Air pressure tube; Fuel pipe; Coated tube conveying tube; Fire hose and other film and plate rotation belt (with a certain tensile effect); An air cushion; Diaphragm; Keyboard board; Composite fabric

TPU is a thermoplastic polyurethane, polyester type and polyether type points, it has a wide hardness range (60HA-85HD), wear resistance, oil resistance, transparent, good elasticity, in daily necessities, sporting goods, toys, decorative materials and other fields are widely used, halogen-free flame retardant TPU can also replace soft PVC to meet more and more areas of environmental protection requirements. TPU brands are numerous, the quality is uneven, the selection of TPU should go through a detailed evaluation and demonstration, otherwise it can not get a good cost-effective results.

TPU This material can soften at a certain heat, but can remain unchanged at room temperature. It is used in shoes for stability and support. TPU, also known as polyurethane rubber, is a kind of polyurethane, which is a relatively emerging product in China, and is widely used in the shoe industry, pipe... And other industries.
