IROGRAN® A 87 H 4615

Polyester-based Thermoplastic Polyurethane

Product Description:

IROGRAN® A 87 H 4615 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

At Jan.2016: US / EAIME / APAC MTS / MTS / MTO finished 08.10.2016 08/17/2021 by Lidina Canuto: Updated existing data which is based on the DIN/ISO since this is German made, but remove ASTM data. 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.
