PU called the  polyurethane, is on the main chain containing repeat carbamate groups of macromolecular compounds. It is made of organic diisocyanate or more isocyanate and polyol dihydroxy or addition polymerization.

Polyurethane foam plastics is used widely at present.

Polyurethane elastomer can be in a wide range of hardness has high elasticity and strength, excellent wear resistance, oil resistance, fatigue resistance and seismic resistance, with \"wear-resisting rubber\". Polyurethane elastomer in polyurethane products production are small, but the polyurethane elastomer has excellent comprehensive performance, has been widely used in metallurgy, petroleum, automobile, ore dressing, water conservancy, textile, printing, health care, sports, food processing, construction and other industrial sectors.

PU PU, PU leather is PU ingredients skin. Now clothing manufacturer of this kind of material production is widely used clothing, commonly known as imitation leather clothing. PU is the abbreviation of English polyurethane, chemical name in Chinese Polyurethane (pu) Its quality is good or bad, the good imported PU leather bags;

Polyurethane composite board is also called PU sandwich panel.

Polyurethane as the core material of composite board is composed of the lower choi steel on the middle foam polyurethane, adopts world advanced mixing pouring technology of the six components of on-line automatic operation can be one-time completed online social ingredients center or factory proportion mixing technology, and can online adjust according to the temperature, so as to produce a distinctive high strength, energy saving, green environmental protection material.

Because of its fire protection moistureproof performance is good, also other materials commonly used in composite board sealing side core material, polyurethane sealing side composite board is made of high quality color coated steel plate for the surface material, continuous rock wool, glass wool, cotton as the core material, high-density hard foamed polyurethane as the tongue-and-groove filling, after high pressure foaming solidified, automatic solid cotton cloth and controlled by the super-long double crawler molding compound and into, compared with the traditional hang cotton maintenance materials, fire prevention, heat preservation effect is better, more durable performance, convenient installation, elegant appearance. Is to be the leader of the steel building maintenance materials.

Commonly used in the structure of the roof outer plate, the plate has good heat preservation, heat insulation, sound insulation effect, and polyurethane as auxiliary combustion, comply with the fire control safety. Polyurethane were added on the joint action, has the very high strength and stiffness, the lower plate is smooth level off, the line is clear, increase indoor aesthetic, flatness. Easy installation, short time limit, and beautiful, is a new kind of building materials.

The sandwich board is light, beautiful and good anti-corrosion performance, and can be directly processed, it to construction, shipbuilding, automobile manufacturing, furniture industry, electrical industry provides a new type of raw materials, such as the steel for wood, such as efficient construction, save energy and prevent pollution.
