Adiprene LFP 2950A PPDI-terminated polycaprolactone prepolymer Crompton-Uniroyal Chemical PU - Prepolymers >> Caprolactone based ADIPRENE® LFP 2950A is a PPDI-terminated polycaprolactone prepolymer having very low free PPDI content (typical < 0.1%) for easier management of health and safety during handling. This prepolymer is similar to ADIPRENE PP 1096 in composition and performance. ADIPRENE LFP 2950A yields high performance 93-96 Shore A hardness elastomers when cured with VIBRACURE ® A 250 or HQEE. The high performance features of ADIPRENE LFP 2950A are due to PPDI (p-phenylene diisocyanate), a special building block that imparts exceptional properties to cast polyurethane elastomers. The unique combination of properties exhibited by PPDI-based prepolymers is superior to those available from standard prepolymers based on TDI or MDI. Low Free PPDI Content Low Viscosity and Easy Melting Long Pour Life Excellent Dynamics Good Tensile/Tear Strength Excellent Resilience PPDI-terminated polycaprolactone prepolymer. Possesses very low free PPDI content, low viscosity and easy melting, and long pour life. Imparts very good properties to cast polyurethane elastomers. Provides very good dynamics, good tensile/tear strength and very good resilience.
