Huntsman introduces new Irogran grade

From Huntsman comes a new TPU that is said to offer a broader temperature operating range than standard grades. Irogran A 92 K 5031 DP – the first grade in a new line – can be extruded or injection-molded to create elastomer components for heavy-duty engineering equipment, engines and hydraulic systems where working conditions may be from +130 °C to -40 °C.

Offering high strength at room temperature, a low compression set at 100 °C and consistent form retention and stability up to 120 C, the new TPU is suited for the manufacture of pneumatic tubes, spiral hoses, timing belts and cable jackets employed in high temperature applications such as automotive brake and engine systems. The product's good anti-burst properties and capacity to resist long-term exposure to oils, hydrolysis, chemicals and abrasion also makes it a reliable base material for hydraulic seals.

Helmut Witt, new business development manager at Huntsman Polyurethanes said: "In the production of flexible elastomeric parts, the most successful materials are those that offer infinite processing possibilities and performance scope alongside consistent quality. Irogran A 92 K 5031 DP is made using a special technique developed by Huntsman. Employing raw materials economically, this process delivers optimized hard block products of an extremely reliable standard. With a range of properties that function regardless of temperature fluctuations, Irogran A 92 K 5031 DP stands out as an important new raw material for industrial applications where performance, even in the most extreme conditions, is mission critical."
