Adiprene® LFP 1950A

About
ADIPRENE LFP 1950A is a PPDI-terminated polyester 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 1095H in composition and performance, while offering significant processing advantages including easier melting, lower viscosity, and increased pour life. ADIPRENE LFP 1950A yields a high performance 93-95 Shore A hardness elastomer when cured with VIBRACURE® A 250. The high performance features of ADIPRENE LFP 1950A 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. Features of ADIPRENE LFP 1950A include: Low Free PPDI Content Lower Viscosity and Easier Melting Increased Pour Life Excellent Dynamics Excellent Tensile/Tear Strength Excellent Resilience&&
