Wyandotte, Michigan - BASF Corp. introduced two new tough, halogen-free, high-heat grades of thermoplastic polyurethane (TPU) for wire and cable jacketing applications at the annual 2008 IWCS (International Wire and Cable Show) in Providence, Rhode Island, 9-12 Nov. Both TPUs, from BASF's TPU business unit, show excellent abrasion resistance, toughness, low temperature properties, hydrolytic stability and fungus resistance in standard DIN tests, the company said.
New Elastollan 1190 A 10 FHF TPU is a non-halogenated fire retardant grade for cable jacketing and other uses, with Shore A hardness of 90, ensile strength of 25 MPa (between other BASF grades) and a good tear strength of 60 N/m. Abrasion loss is 30 mm3. These specifications will suit users seeking performance specifications that fall in between other BASF grades, said the group.
BASF also featured its Elastollan 1185 A 10 F001, a polyether-based TPU compound that uses a halogen-containing flame retardant. It is formulated for extrusion applications that include cable jacketing, film/sheet, hose and hose jacketing and profile extrusions. This TPU has Shore A hardness of 87, tensile strength of 29 MPa, and an extremely high tear strength of 96 N/mm, BASF said.
