What are the types of polyurethane products
As a kind of raw material, polyurethane material has developed rapidly since the industrial production was put into the market in the 1950s. Compared with polymer rubber materials, it has unique advantages, according to different performance needs, through different production processes, to produce polyurethane products with different properties and properties, which are widely used in a variety of fields. So what are the types of polyurethane products?
1. Soft foam
The production process of this product is generally two-component liquid reaction molding, which can be made into products with uniform foam structure.
The main function of polyurethane soft foam products is cushioning, which is representative of shock absorption products and mattress products. This product has strong adaptability to temperature, and the product compression does not deform more than 10%. As a shock absorption product, it is not only used in elevators and other devices, but also in shock absorption and damping elastomer accessories in the automotive industry.
2. Hard products
This polyurethane product is a thermosetting plastic, closed cell structure, with thermal insulation and waterproof functions, and is currently the lowest thermal conductivity of all the same level of thermal insulation materials. Polyurethane hard products are mainly used in the construction industry, such as external wall insulation panels, refrigeration equipment and cold storage insulation materials, pipeline insulation materials.
3. Elastomer
Polyurethane elastomers are also widely used, from mechanical parts to tires, from waterproof materials and tapes to synthetic leather and polyester fibers.
It is mainly divided into three kinds, casting type polyurethane elastomer (CPU) CPU, easy to form, suitable for the manufacture of large products, can be used for synthetic leather, sports track, building waterproof materials and so on; Thermoplastic polyurethane elastomer (TPU) (TPU, it can be plasticized by heating, can be dissolved by using solvents, and has the characteristics of high strength and high toughness. Good processing performance, can be manufactured into spandex fiber, insoles, sports equipment, wire and cable sheath;
