1, TPU development prospects

TPU is mainly used in inflatable, health / medical products, vacuum molding, tape, foam cushion, belt, protective layer, and pad.

Currently, based mainly on the domestic low-end production TPU, therefore China in high-end market development potential is huge.TPU in many fields exist great application prospect, TPU is mainly used for melt spinning spandex, shoe industry, synthetic leather, film industry, hose and cable industry, castor industry industry, adhesives and so on. But at the same time in many areas is facing strong substitute competition, domestic producers of TPU only constant innovation investment, increase R & D depth of TPU, reduce the production cost to get persistent development and the promotion and application of TPU products to more areas.

TPU film is mainly used in senior fabric laminate can be used in clothing, footwear, thermal underwear and agricultural use cold film.TPU film also can be for welding type hollow products, fabric layer, protective coatings, foam packing material, abrasion resistant coating.
TPU film and sheet can be formed by extrusion machine extrusion, thickness from a few microns to several millimeters, and can join pigments have a variety of colors of the products.TPU film resistance, puncture resistance of, tear resistance, flexibility, adhesion, weldability is good, so it can be used for preparation of the conveyor belt in the, and according to the different types of TPU were used to transport dry, wet, fat class food.

Special TPU varieties also meet the requirements of the German health board (BGA) for food contact materials, as well as the U.S. Food and Drug Administration (FDA) of the relevant requirements.

2, TPU is widely used, mainly for the following areas:

Footwear: TPU in footwear production has a wide range of uses, mainly used as material for shoe sole and shoe accessories, such as signs, shoe buckle, decorative pieces and outer sole, transparent uppers, and so on, instead of rubber and thermoplastic polyolefin and other materials.

Hoses: TPU hose is widely used in aircraft, tanks, gas of automobile, motorcycle, machine tools and other machinery and equipment, oil hose. TPU production pipe has the advantages of good flexibility, size stability, good transparency, resistance to chemicals and good resistance to hydrolysis, no pollution, pressure resistant performance good.

Melt spinning spandex: fiber grade TPU production of melt spinning spandex has good elasticity, easy downstream processing, no pollution, storage period is long, resistance to chemicals and water solution.

Car: mainly used for body parts, fenders, side body parts, coupling, bumper, bushings, gaskets, seals, wing nut, instrument cover and the oil pipe sleeve.

Wire and cable sheath: must be able to protect the insulation layer from the climate, environment, the influence of hydrolysis and other physical damage.TPU can meet the demanding requirements of the field, with excellent low-temperature flexibility, weather

resistance, moisture resistance and antibacterial

Films and sheets: production of TPU film and sheet with excellent low-temperature flexibility, wear and tear resistance of good, good transparency, color, has the advantages of easy. Is mainly applied in the fields of lifeboats, life jackets, raincoats, conveyor belt, folding storage tanks and so on.

adhesives are widely used in surface treatment of polyester and nylon, PU fabric and leather, resistant to chemicals, UV resistance, hydrolysis resistance, low temperature flexibility, high elongation, excellent characteristics of bending fatigue performance.
Varnishes and inks: TPU adhesive can be mixed with pigment and solvent prepared varnish and ink, varnish and ink can spraying or printing and coating to different substrates, the main application areas are sports shoes, handbags, umbrellas, interior decoration, toys and so on.

Coating solution: TPU can be directly coated or transfer coating. Fabrics coated with PVC or polyurethane foam and then TPU solution fabric coating can be made high performance products, instead of leather used in indoor decoration, handbags, luggage and other products.

Antistatic and conductive material: studies have shown that the failure of 25%-75% electrical components are related with the accumulation of static electricity, thermoplastic plastic alloy can be permanent antistatic, eliminates the electrostatic hazards and pollution.
