PU is short for polyurethane, which is a new type of organic polymer environmental protection material and is widely used in the market.
1. Water resistance: closed cell structure, no water absorption, moisture resistance, good water resistance. 2. Structural stability: strong adaptability to the deformation of the main structure and good crack resistance. 3. Moisture and heat resistance: whether it is high temperature or cold climate, it is difficult to cause irreversible damage or deformation to its structure. 4. Durability: it has a good name of "wear-resistant rubber", with stable porosity structure, excellent heat preservation performance, freeze-thaw resistance and sound absorption performance. 5. Environmental Protection: acid-resistant, alkali-resistant and heat-resistant. Polyurethane is solvent-free and non-fluorolithium-ion type, which will not produce harmful gases and cause harm to the environment.
