Abstract

See full text

The present invention is a flame-retardant polyolefin/thermoplastic polyurethane formulation made from or containing a polyolefin, a thermoplastic polyurethane, and an intumescent, polyphosphate flame retardant composition. The invented system achieves elongations >400% and tensile strengths >1500 psi while the same polyolefin only achieved 100% elongation and <1000 psi tensile strength. Also, the present invention shows improved tape extrusion performance versus a comparable TPU only composition, indicating improved melt rheology/fabrication capability for extrusion applications.
