Huntsman (The Woodlands, Texas / USA; www.huntsman.com) has launched a family of halogen-free, flame retardant cable jacketing materials that are said to offer an enhanced reaction to fire properties along with unprecedented strength and fatigue resistance. The “Irogran” range initially includes three products: “A 90 P 5014 FR TPU”, a base line material for the most common applications, “A 91 P 5015 FR TPU” that is suitable for more demanding applications and flagship grade “A 92 P 5016 FR TPU” for the most demanding end-uses.

The US chemical company said that trials by leading wire and cable producers have shown that Irogran A 90 P 5014 FR TPU typically retains 80% of its original tensile strength after seven days of heat exposure, which is up to 14% better than competing materials. In addition, when exposed to oil at 100 °C over 42 days, samples of Irogran A 91 P 5015 FR TPU were up to 45% stronger than comparable products.

Irogran products have been designed for use in automation, transportation, energy and consumer electronics applications where flame retardancy is essential. The products are also free of plasticisers and fully recyclable.
