Huntsman Polyurethanes has become one of the first major providers of thermoplastic polyurethane (TPU) to offer a non-blooming, matt, polyester-based material to the wire and cable market. The new Irogran A 85 C 5024 DP material eliminates the risk of blooming, an undesirable effect that occurs when additives migrate to the surface of a material and become visible. Although blooming does not affect the mechanical performance of cables, it is unsightly and is an issue that cable manufacturers around the world are keen to resolve. This halogen-free, polyester-based TPU features a consistent matt finish and stable extrusion qualities and is well suited to wire and cable applications such as jacketing, spiral and data cables.
