Description

Low Free TDI/Polyester Prepolymer LFE4390 Equivalent to LF1900A


1. Description

LFE4390 is a TDI-polyester-based product with a very low free TDI content (typically less than 0.1%). This results in a non-toxic polyurethane system and reduces processing hazards. LFE4390 offers lower viscosity, longer pot life, and faster demolding. Its compatibility with a range of curatives enables high productivity. The resulting elastomer exhibits good abrasion resistance, compression set, tear strength, and dynamic properties.
