Tecnate EMN 2501

Tecnate EMN 2501 prepolymer for molding components in the 85 Shore A hardness range when cured with 1,4-butane diol. Elastomers made from Technate EMN 2501 have excellent low temperature properties, high abrasion resistance, outstanding hydrolytic stability and high resilience. Technate EMN 2501 is a MDI-terminated prepolymer based on a propylene glycol polyol. The material can be cured with a variety of materials to yield various hardnesses.
