Baytec® prepolymers
Baytec® polyurethane prepolymers are used in the production of polyurethane cast elastomer parts, polyurethane adhesives and polyurethane sealants. Baytec prepolymers are offered in polyether and polyester grades, which provide processors the ability to tailor polyurethane formulations for specific physical properties, such as tear strength, abrasion resistance and compression set. Additionally, Baytec WE-180 and Baytec WP-260 are special aliphatic (light-stable) grades of prepolymer for demanding applications.
