| NYCOA 2176 is a high viscosity resin particularly suitable for extrusion processing. Its high melt viscosity and extremely good melt strength provides ease of processing for tubing, complex profile, and mandrel extrusion. NYCOA 2176 was specifically formulated to offer high flexibility and strength, superior toughness and high impact resistance, even at low temperatures. The alloy offers improved recyclability with minimum loss in physical properties after repeated extrusi This material performs well in applications where softness, ductility and exceptional impact resistance are required. NYCOA 2176 is available with custom additive packages: heat stabilizer, UV stabilizer and/or flame retardant. Typical extrusion applications include hose mandrels for rubber vulcanization, high-pressure & hydraulic hoses, and flexible & vacuum tubing.&& |
