What is Polyester/TDI Polyurethane Prepolymer?
Polyester/TDI (Toluene Diisocyanate) polyurethane prepolymer is a reactive compound based on polyester polyols and TDI. It is widely used to produce polyurethane products known for their high strength, abrasion resistance, and excellent elasticity. This prepolymer offers good processing performance and can maintain stable physical properties in high-temperature environments, while also providing excellent adhesion and chemical resistance.
What is the main Applications of Polyester/TDI Polyurethane Prepolymer?
Industrial Tires and Rollers
With high strength and wear resistance, polyester/TDI prepolymer is ideal for manufacturing industrial tires, rollers, and other components that require excellent performance in high-load and abrasive environments.
Elastomeric Parts
Suitable for producing various elastomeric components, such as seals, gaskets, and shock-absorbing pads, providing long-lasting elasticity and impact resistance.
Coating Materials
Used in making high-wear-resistant coatings, such as inner and outer pipe coatings, floor coatings, waterproof and anti-corrosion coatings, protecting substrates from wear, corrosion, and chemical damage.
Shoe Soles and Footwear Materials
