Polyester TDI100 Polyurethane Prepolymer is a high performance, toluene diisocyanate based prepolymer designed for producing polyurethane elastomers with excellent mechanical properties. Formulated with a polyester backbone, this prepolymer offers exceptional wear resistance, high tensile strength, and superior dynamic performance, making it well-suited for demanding industrial applications.
Product description
Polyester TDI100 Polyurethane Prepolymer for PU screens is a polyester-based polyurethane prepolymer, formulated from adipic acid based polyester polyols and TDI100 (toluene diisocyanate). This prepolymer belongs to the TDI series of polyurethane systems and is widely used in various industrial and manufacturing applications.
The polyester/TDI prepolymer system provides excellent mechanical strength, flexibility, and abrasion resistance, making it ideal for casting polyurethane elastomers. It offers good processability, stable performance, and reliable durability under demanding conditions.
Typical applications include PU screens, industrial rollers, wear-resistant parts, and other elastomer products where high performance and resilience are required.

Other Common Applications to Polyester TDI-100 Polyurethane Prepolymer's:
Industrial Sealants and Coatings: Used in the production of industrial equipment sealants and protective coatings, offering protection and longevity.
Adhesives:Utilized in the production of high-strength adhesives, commonly used in construction, automotive, and aerospace industries.
Elastomers and Molded Products:Used in the manufacturing of various elastomer products such as hoses, seals, and gaskets.
Prepolymers should be stored in a dry, low-temperature place and protected from moisture and moisture during use.
The 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.
