Introduction to TPU:

TPU (Thermoplastic polyurethanes) is a thermoplastic polyurethane elastomer rubber. Mainly divided into polyester and polyether type of points, It is widely used in the fields of daily necessities, sporting goods, toys, decorative materials and so on. Halogen-free flame retardant TPU can also replace soft PVC to meet the requirements. To the more areas of environmental requirements.

The so-called elastomer refers to the glass transition temperature is lower than the room temperature, elongation at break> 50%, external recovery after recovery is better polymer materials. Polyurethane elastomers are a special category of elastomers. The polyurethane elastomers have a wide range of hardness and a wide range of properties. Therefore, polyurethane elastomers are a kind of polymer material between rubber and plastic. Can be heated plasticized, chemical structure is not or rarely cross-linked, the molecules are basically linear, but there is a certain physical cross-linking. This type of polyurethane is called TPU.

The main features of TPU are:

Hardness range: by changing the TPU reaction components of the ratio, you can get different hardness of the product, and with the increase in hardness, its products still maintain good flexibility and wear resistance.

High mechanical strength: TPU products carrying capacity, impact resistance and shock absorption performance.

Cold resistance highlights: TPU glass transition temperature is relatively low, at minus 35 degrees still maintain good flexibility, flexibility and other physical properties.

Good processing performance: TPU can be a common thermoplastic materials processing methods, such as injection molding, extrusion, rolling and so on. At the same time, TPU and some polymer materials can be co-processing performance of complementary polymer alloy. Oil, water, resistant to mold. Good recycling efficiency.

Polyurethane elastomer (PU Elastomers)

Pouring type polyurethane elastomer (referred to as CPU) - polyurethane elastomer is the most widely used, the largest one;

Thermoplastic polyurethane elastomer (TPU) - Thermoplastic polyurethane elastomer accounts for about 25% of the total amount of polyurethane elastomers;

Mixing polyurethane elastomer (MPU) - about 10% of the total amount of polyurethane elastomer.

Microporous Elastomer - Polyurethane Microporous Elastomer The most typical application is for footwear. Modified TPU - TPU resin hose manufacturing enterprises concentrated in Guangdong, Zhejiang, Jiangsu, Shandong, Hebei and other places. TPU provides a tear resistance, wear and bending characteristics, resistance to high and low temperature is the key to cable performance. So in the Chinese market, higher cables such as control cables and power cables with TPU, used to protect the design of complex cable coating materials, the use is also increasingly widespread. Polyurethane elastomers with its high mechanical strength, excellent wear resistance, excellent oil resistance, acid and alkali resistance, outstanding anti-compression and make it in a large number of applications on the wheel. The main domestic wheel are the following: industrial roller, home wheel, sports equipment wheel, medical equipment wheel, toy wheel. TPU ink main advantages are: excellent adhesion, low viscosity, good resistance to flexing, excellent wear resistance, high gloss, weather resistance, including UV exposure, including any sun exposure, in the Kind of application field are excellent performance and toughness and durability. Aromatic and aliphatic TPU inks can be used in a variety of climatic and environmental conditions, the product has a stable and outstanding performance. TPU ink has a smooth appearance, good shading and alcohol resistance, strong adhesion and other characteristics, mainly for TPU and other plastic surface decoration. Such as mobile phones, laptops, shoes, car leather chairs, sofa, senior leather goods, handbags, inflatable entertainment TPU products, umbrellas, raincoats, TPU ink for metal, glass, poor adhesion, easy to paint.
