Cast polyurethane prepolymer is an excellent elastic material with good elasticity, abrasion resistance, crack resistance, oxidation resistance and chemical resistance. This material is used to manufacture various gaskets, seals, liners, vibration isolation pads, rubber sheets and other products, and is widely used in machinery, automobiles, chemicals, construction, aerospace, metallurgy and other industries.
According to different parameters such as hardness, elastic modulus and density of cast polyurethane prepolymer, it can be divided into various types, such as: polyester prepolymer, polyether prepolymer, PTMG polyurethane prepolymer, MDI Series of prepolymers, two-component series of prepolymers, etc.
Advantages of cast polyurethane prepolymer:
1. High strength: cast polyurethane elastomer has high physical strength and can withstand heavy loads and vibrations.
2. Excellent elasticity: The material has very good elastic properties and can maintain good elastic recovery in a large deformation range.
3. Excellent wear resistance: the material has a smooth surface and good wear resistance, which can be used for a long time and reduce the number of replacements.
4. Good oxidation resistance and chemical resistance: the material can be used in harsh environments and is not easily oxidized and corroded.
5. Easy to process: Casting polyurethane elastomer can be cut and processed according to the size.
The scope of application of cast polyurethane prepolymer:
Casting polyurethane elastomer can be widely used in machinery, automobile, chemical industry, construction, aerospace, metallurgy and other industries. For example:
1. Machinery: Casting polyurethane elastomers can be used to make various mechanical seals, vibration isolation pads, gaskets, rubber sheets, etc., which can perform functions such as vibration isolation and noise reduction, impact buffering, and mechanical protection.
2. Automobiles: Casting polyurethane elastomers can be used to make automobile chassis, shock absorbers, tires and other components, which can play the role of shock absorption and noise reduction, and improve driving stability.
3. Chemical industry: Casting polyurethane elastomer can be used for seals, vibration isolation pads, rubber sheets, etc. of chemical equipment, and can withstand harsh conditions such as strong chemical corrosion and high temperature and high pressure.
4. Construction: Casting polyurethane elastomer can be used to make building sound insulation pads, shockproof rubber sheets, etc., which can reduce noise, resist earthquakes and prevent disasters.
In short, the cast polyurethane prepolymer independently developed and produced by our company is an excellent elastic material with broad application prospects and has been more and more widely used in various industries.
