The main use of polyurethane sponge
One: clothing and sporting goods
Polyurethane changes the style of clothing and plays a role in our lives. It represents a spandex elastic fiber that is comfortable, soft, flexible and elastic. In addition to the puffs, pantyhose, and socks used for women's makeup, it is also used in ski jackets, swimwear, etc., and its amazing stretchability is greatly utilized by Zui. In sports such as skiing and yachting, polyurethane coatings are selected for their excellent wear resistance and weather resistance. The rigid foam having a light weight and good wear resistance is used as a core material for skis and surfboards, and a polyurethane elastomer having excellent elasticity and abrasion resistance is used as a sole of a sports shoe.
Two: daily necessities
In terms of room supplies, polyurethane applications show their comfort. Polyurethane coating gives the surface of furniture, piano and other musical instruments a beautiful luster and plays a strong protective role. The soft foam is used as a cushion material commonly used by Zui and a healthy bedding that disperses body pressure. In the case of kitchen products, rigid foam is used for heat insulating materials such as refrigerators. A polyurethane resin having good adhesion to a plastic film is used as an adhesive for food packaging. There are also applications in sealing materials, diapers and physiological products for water purifiers. Polyurethane elastomers that are harmless to the human body are also expanding in their use. In addition, in our lives, polyurethane artificial leather, synthetic leather, foam, etc. are made into bags and shoes, and are highly praised for their natural style and durability.
Three: electronic supplies
Promoting the development of the electronics industry is also the mission of polyurethane. Polyurethane adhesives with excellent abrasion resistance and adhesion are used as adhesives for magnetic materials of various recording media in the manufacturing process of recording/video tapes, computer disks, IC cards and electronic tickets, so that the recording density is obtained. improve. In addition, polyurethane insulating sealing varnishes are used to make enameled wires. Ultraviolet (UV) curable polyurethane is made into a fiber optic cable. In recent years, polyurethane adhesives have also been applied to printed circuits and the like, and have been continuously developed and applied to meet the requirements of the times.
Four: medical equipment
Polyurethane is also contributing to the advancement of the medical industry. Polyurethane elastomers have excellent human adaptability, adhesion and antithrombotic properties due to their specific structure, and are used as a good end cap material for the fixation of hollow filament bundles of artificial kidneys. And further improve its anti-blood and human body adaptability, and actively carry out applied research on artificial heart and artificial skin.
Five: car transport
The automotive industry's requirements for comfort, safety and energy saving in the future of automobiles are inseparable from polyurethane. A roofing material with heat insulation and sound insulation, a car seat cushion with comfort requirements, and a vehicle bottom material and sealing material that block noise and vibration to maintain a quiet space. In addition, there are dashboards, doors, airbags, seat backs, fenders, absorbent absorbers, oil seals, non-explosive tires and paints. Various polyurethane products are used in all corners of automobiles. In addition, it has also been made into a tire chain, which is valued for its flexibility, durability and properties that do not impair the road surface. In addition, polyurethane coatings with excellent durability/weather resistance are also used in the coating of motorcycles, light rail vehicles, Shinkansen and ships.
Six: building civil engineering
Polyurethane also exhibits its properties in the construction/civil sector. Hard foam for residential use as a thermal insulation material for Zui, applied to walls, floors and roofs, greatly reducing the supply of air-conditioning and heating, and complying with energy-saving requirements. Polyurethane coatings are also used for exterior wall coatings for residential decoration because of their excellent weather resistance. In addition, polyurethane waterproofing is used as a floor coating for buildings such as hospitals and gymnasiums, as well as anticorrosive coatings for high-rise buildings and bridges, using its waterproofness, chemical resistance and appropriate elasticity. Polyurethane is also widely used as a cushioning material between sleepers and rails, as a waterproofing and sealing material for building roofs, and as a binder for wooden mobile homes. It is also used in the construction of all-weather runways and golf courses.
Seven: industrial materials
Polyurethane is also an indispensable industrial material. For example, an elastomer that is excellent in abrasion strength by molecular design is used in OA machines such as copiers and printers, and rollers for papermaking, iron making, electroplating, etc., and is used for belts, tubes, and sheets for various purposes. Film material. The development of its processing technology is also very active. In addition, polyurethane foams have excellent thermal insulation and durability and are used as insulation materials in LNG storage tanks and floor storage facilities. Polyurethane adhesives are used in the production of wood fiberboard such as wood chip and medium density board (MDF), which can avoid the release of formaldehyde during home decoration and is receiving increasing attention.
