Product description
High Wear Resistance Polyurethane Prepolymer is TDI Ester Based Polyurethane, it is a high-performance elastomer known for its superior mechanical strength, wear resistance, and load-bearing capacity.
High Wear Resistance Polyurethane Prepolymer is widely used in industrial applications where high abrasion resistance and chemical resistance to oils and solvents are required. However, its susceptibility to hydrolysis in wet environments makes it more suited for dry or oil-laden conditions.

Advantage
High Wear Resistance Polyurethane Prepolymer offer numerous advantages, including excellent mechanical properties such as high tensile strength and elongation at break, and versatile final PU products whose properties can be tailored by adjusting the molecular weight and structure of the polyester prepolymer.
High Wear Resistance Polyurethane Prepolymers exhibit good chemical resistance, thermal stability, and flexibility, allowing them to be used in applications ranging from flexible foams to rigid foams with high load-bearing capacity.
High Wear Resistance Polyurethane Prepolymer also possess excellent abrasion resistance, making them suitable for products like shoe soles and conveyor belts.
The ability to customize these prepolymers by using different types of polyester polyols and varying the TDI ratio results in a wide range of properties.
Additionally, they can contribute to sustainability and economic efficiency in production, making polyester/TDI-based polyurethanes competitive in the market.
Using
After the High Wear Resistance Polyurethane Prepolymer is vacuum degassed at 80-85°C, it is mixed with melted MOCA, degassed, poured, and vulcanized for molding. It is suitable for manual operation and mechanical molding.
High Wear Resistance Polyurethane Prepolymer should be stored in a dry, low-temperature place and protected from moisture and moisture during use.
High Wear Resistance Polyurethane Prepolymer after opening should be used up as soon as possible. If it is not used up, it is best to seal it with nitrogen.
The shelf life of unopened prepolymer is 6 months.
If you want to add color paste or other materials, please keep the water content of the additive below 0.1% and consider the compatibility of the additive.
