Polyurethane resin - Names and Identifiers
Polyurethane resin - Introduction
Polyurethane is an important polymer material with the following properties:
1. High strength: Polyurethane resin has high strength and rigidity, and can maintain stability under different stress conditions.
2. Good wear resistance: Polyurethane resin has excellent wear resistance and can be used to make wear-resistant materials and coatings.
3. Good chemical resistance: Polyurethane resin has good resistance to a variety of chemical substances and can be used to make chemical storage containers and pipelines.
4. High elasticity: Polyurethane resin has excellent elasticity and can be used to make elastomers, springs and shock-absorbing materials.
5. Good weather resistance: Polyurethane resin has excellent weather resistance and can maintain stability and durability under different climatic conditions.
Polyurethane resin has a wide range of uses:
1. Building materials: can be used to make insulation materials, sealing materials and floor materials.
2. Transportation: It can be used for auto parts manufacturing, aerospace materials and tire manufacturing.
3. Furniture and textiles: can be used to make furniture filling materials, mattresses and textile coatings.
4. Medical Devices: can be used to make artificial heart valves, medical glue and artificial bones.
There are two main methods of making Polyurethane resin:
1. One-step method: Polyurethane resin is formed by directly mixing and reacting various raw materials (such as Polyether polyol, isocyanate, etc.).
2. Two-step method: first prepare polyol prepolymer, and then form Polyurethane resin under specific conditions through the reaction with isocyanate.
When using Polyurethane resin, you need to pay attention to the following safety information:
1. Wear protective glasses and gloves during operation to avoid direct contact.
2. Avoid prolonged exposure to high temperature to avoid thermal decomposition and harmful gases.
3. Operate in a well-ventilated environment to avoid inhaling volatile substances.
4. Avoid direct sunlight and humid environment during storage, so as not to affect its performance.
5. Waste materials should be disposed of in accordance with local regulations to avoid environmental pollution.
