TPU (Thermoplastic polyurethanes), the thermoplastic TPU elastomers are made by the MDI NCO functional group-containing OH-containing functional group POLYOL 1.4BG and made by extrusion kneading. It has good flexibility, good physical properties, and its mechanical strength is good, therefore, it is widely used for injection, extrusion, rolling and dissolved into the resin solution processing, plastic processing industry often use plastic material made products cover a range of industrial applications and essential civilian needs. In recent years, due to the continued development of new products, the amount of thermoplastic PU elastomers are continuing to increase in the plastic processing industry to create a low-cost, high value-added industry a new opportunity.tpu film is a feature film, with other plastic materials cannot match the high strength, good toughness, cold resistance, oil resistance, aging resistance, climate, environmental non-toxic, biodegradable characteristics, but also has high waterproof and breathable, wind, cold, antibacterial, warmth, anti-ultraviolet and energy release many excellent features, so it is widely used in various fields.
Advantage of TPU Film
TPU (thermoplastic polyurethane) is increasingly welcomed by the people because of its superior performance and environmental protection concept. Any use of PVC, TPU can become a substitute of PVC. TPU have the advantage that PVC does not have. TPU not only has excellent high-tension, high tension, tough and anti-aging properties, and is the kind of mature green material.waterproof film has been widely used in: shoes, clothing, inflatable toys, water and underwater sports equipment, medical equipment, fitness equipment, car seat material, umbrellas, luggage, handbags and other TPU film TPU on the basis of particulate material formed into a film by calendering, casting, blown film, coating, and other processes.
Application of TPU Film in Sport Shoes
Manufactured by using a special process thickness between 0.015-0.025mm TPU film has excellent waterproof and breathable performance. This TPU film can fit together with Lycra, cotton fabric, and can be made out of waterproof and breathable excellent functional fabrics, widely used in snow suits, raincoats, trench coat, winter clothes, and field service. This TPU film can also be divided into high, low moisture permeability of three, and waterproof up to 10,000 mm water column, moisture permeability can reach 10,000 g/m2/24h. Currently, there are extremely wide ranges of applications in sports shoes: soles and uppers trademarks decoration, air bags, air cushion, and oil. Today, TPU film used in sports shoes have two trends: First, the wind blowing the popular women sandals, transparent TPU film or crop, or screen printing color or fit cloth base into the mesh folder, and so on, the high frequency forming and adhesive in the upper, functional and decorative effect. TPU film waterproof and breathable shoe materials cloth is also fit to use in order to achieve the effect of waterproof and breathable.
www.tpufilm.net is the first private enterprise with many TPU film production lines in China. Since 2006, our company has been engaged in R & D of TPU film products, and our polymer elastomer film has excellent characteristics of warping resistance, wear resistance, oilstain resistance, ageing resistance, weather resistance, high waterproofness and moisture permeability, hydrolysis resistance, temperature resistance, mould prevention, environmental protection, non-toxicity and recyclability and degradability.
