IROGRAN® A 85 P 4666

Polyether-based Thermoplastic Polyurethane

Product Description:

IROGRAN® A 85 P 4666 is a flame-retardant, halogen-free, melamine-free, polyether-based Thermoplastic Polyurethane (TPU) for extrusion applications. Key features are excellent hydrolysis and microbial resistance, good oil and solvent resistance, excellent wear performance, resistance to dynamic stress, a glossy surface and the material can be crosslinked via electron beam processing to enhance its performance characteristics. .

MAIN APPLICATIONS:

Thin wall technical parts, thin wall extrusion profiles, spiral hoses and cable jacketing.
