Adiprene® BLM 500

Technical Datasheet | Supplied by LANXESS
Adiprene® BLM 500 by Lanxess is MDI based urethane prepolymer with blocked isocyanate. The blocked curing sites allow protracted storage of the polymer in the presence of moisture and active vulcanizing agents. It can be activated by heating and materials made from it have high tensile strength, high elongation and excellent tear strength. They are also low in viscous damping indicating low heat generation and more durability in dynamic applications. Diamine-cured Adiprene® BLM 500 yields vulcanizates having improved performance over common TDI based urethane materials. MDI is one of the most commonly used diisocyanates in industrial polyurethane applications. However, blocked MDI prepolymer and its application are very limited. The residual MDI in the unblocked preoplymer is below 0.5%. It is used in solvent resistant adhesives.
