1. In the defense industry
Polyurethane elastomers are widely used in the defense industry, such as airtight pads for various cannons, bulletproof panels for composite armored vehicles, missile head protection covers, forward flow covers for aircraft, helmet pads, and seats in aircraft and boats. Pad, knee protection, aviation thin-walled fuel tank, helicopter rotor anti-corrosion film, aircraft landing gear retarder leather cup, metal material processing die pad, radar soft waveguide sheath, bulletproof solid tire, explosion-proof fuel tank, tank anti-cleaning material , armored vehicle anti-skid device, rifle butt, air force compensation suit, military balloon, military coated cloth, aerospace battery case, military cable jacket, submarine cable jacket, optical cable jacket, liquid hydrogen resistant seals, marine acoustic rubber, Aviation and marine electrical potting materials and coatings, etc.
2. In the textile industry
Polyurethane elastomers are widely used in the light textile industry, including textile rubber spokes, printing and dyeing printing rubber spokes, papermaking and food processing rubber spokes, chemical fiber pelletizing rubber rollers, fiber drawing rubber spokes, textile speed-increasing wheels, false twisters and swivel wheels, artificial leather, synthetic leather surface coatings and adhesives, artificial deerskin, shoe uppers and soles, multi-purpose PU leather, elastic fibers and elastic films, soft foam mattresses, seat and sofa cushions, Toothed belts and rollers for textile machinery, sewing machine belts and shoe-making adhesives, adhesives and finishing agents for leather, elastic floors for weaving workshops, insulation layers for refrigerators, brightening for decoration of high-end furniture and light industrial products paint etc.
3. In terms of transportation and railways
The consumption of polyurethane elastomers used as automobile parts accounts for the first place in the consumption of polyurethane abroad, such as automobile bumpers, steering wheels and instrument panels, seat cushions, back cushions and front and rear walls of seats in automobiles. Handrail door lining plate, floor and thermal insulation top plate, oil seal oil bag, spherical cup and coupling, etc.
Used in traffic and railways, as well as solid tires, dock fenders and passenger cars cold pads, oil rings of locomotive fuel tanks, baffles and locomotive pin sleeves, and shock pads under train sleepers.
4. In oil fields, coal mines and mines
Polyurethane elastomers are used for oil pipelines and oil storage tanks and thermal insulation materials, polyurethane elastomers are used as linings for mud pumps and pipelines, wear-resistant linings for hydroelectric worm gears, cyclones and pipe cleaners for drilling machines, hydraulic support seals and dump trucks Oil seals for machine and bucket wheel bushings, underground cold forest cable materials and water blocking materials for rapid underground fishing, conveyor belts and rollers, wire pulleys and ore screens, large vibrating screens and coal preparation screens, sand preparation equipment lining and The ore is made of magnetic machine coating, non-ferrous metal ore dressing seeding coating and ore dressing machine inner burden plate, prospecting cable and mining cable sheath, etc.
5. In the machine data industry
Polyurethane elastomers are most widely used in machinery for various oil-resistant, wear-resistant and shock-absorbing seals. Especially in construction machinery, polyurethane seals have become a key structural material, as well as various types of transmission belts, resistant to Grinding linings, bushings and oil bladders, groove linings and supporting spokes for steel pipe straighteners, steel rolling rubber rollers and rolling mill plum blossoms, amphibious bulldozer drive wheels and metal cold-rolled forming die pads, etc.;
6. In construction engineering
Polyurethane elastomer waterproofing materials, caulking materials, cold storage wall materials and house moisture and cold protection materials, elastic floors, adhesives and finishes, simple paving materials and carpets, etc.
7. In medical and sports
Medical polyurethane elastomer is a newly developed variety, which is developing rapidly now and has become more and more widely used. Such as polyurethane artificial heart, artificial kidney, artificial brain and waist, plasma pump, blood vessel, plasma bag, aortic balloon, contraceptive, ureter, prosthesis, cartilage, gastric transcatheter and surgical fixation materials, etc.
In sports, it is used in polyurethane track, badminton court, gymnastics training ground, polyurethane ball leather, sports shoes, ski boots, skis and roller skates, etc.
8. In other aspects
Polyurethane elastomers can also be used as glue for hydro-generator blades, water seal rings, seals and polishing materials, wear-resistant linings for current transformer shells and gray pumps; video tapes, motorcycles and self-life vehicles The military seat and printed electricity island, etc.
