DuPont™ CHDI is a specialty isocyanate which offers outstanding dynamic properties and high temperature stability in cast and thermoplastic elastomers. Due to its small size and molecular symmetry, this aliphatic diisocyanate provides a compact hard segment in polyurethane formulations. CHDI-based elastomers show:
Superior high temperature dynamic properties
Light and color stability
Excellent solvent and abrasion resistance
In addition to CHDI, DuPont products also include PPDI specialty isocyanate. Contact DuPont for information on these products.
