Polyurethane, commonly a new composite material between plastic and rubber, is formed after chemical reaction of polymer polyalcohol and isocyanate through chain extension and cross linkage. It is divided into polyether and polyester according to its backbone chain.

Main characteristics of polyurethane polyurethane:
1. The wear resistance is 3 to 5 times that of ordinary rubber.
2. Wide hardness range, Shore A10 ~ Shore A95.
3. Oil resistance, corrosion resistance, solvent resistance

4. Low thermal conductivity Polyurethane board has small thermal conductivity and good thermal insulation performance, and is the current thermal insulation material.

5.Beautiful shape and easy installation
6.The polyurethane board has good fire resistance
7.Polyurethane board is non-toxic and tasteless
8.Wide operating temperature range
9. Waterproof and moistureproof

The rubber sheet is made of rubber as the main material (which may contain reinforcement materials such as fabrics and metal sheets), and is a sheet product with a certain thickness and a large area obtained by vulcanization, referred to as rubber sheet. The rubber plate has high hardness and general physical and mechanical properties. It can work in air with low pressure and temperature of 20°~+140°C. The rubber sheet is made by compounding or extruding of the compounded rubber through calendering, vulcanization with a flat vulcanizer or continuous vulcanization with a drum vulcanizer. Color: black, gray, green, blue, etc. It is widely used in industrial and mining enterprises, transportation departments and housing ground. Used as sealing rubber ring, rubber pad, door and window seal and laying workbench and floor。

Polyurethane sheet and PU polyurethane rubber sheet has beautiful appearance and good overall effect. It integrates load-bearing, heat preservation, fire prevention and waterproofing, and does not require secondary decoration. It is fast and convenient to install, short in construction period, and has good comprehensive benefits. It has good cost performance advantages and is a versatile potential. The high-efficiency and energy-saving building envelope material is also a new type of energy-saving sheet advocated and promoted by the Ministry of Construction.
