IROGRAN® A 87 H 4615 R

Polyester-based Thermoplastic Polyurethane

Product Description:

IROGRAN® A 87 H 4615 R is a polyester-based Thermoplastic Polyurethane (TPU) for injection molding applications. Key features are plasticizer-free, excellent wear performance, resistance to dynamic stress, high elasticity and robust processing.

MAIN APPLICATIONS:

Thick wall technical parts and thin wall technical parts.

Details

08/17/2021 by Lidina Canuto: Create A new TDS only reporting ASTM standards since US Made. Reason: Ringwood’s A 87 H 4615 formulation is distinctly different from OSN made. RWD uses a mix polyol approach while OSN made material uses only 1 polyol.
