Broad temperature range TPU can be extruded or injection moulded

26 January 2011

Huntsman has developed the first product in a new line of thermoplastic polyurethane (TPU) that offers a broader temperature operating range than standard grades. IROGRAN A 92 K 5031 DP can be extruded or injection moulded to create elastomer components for heavy-duty engineering equipment, engines and hydraulic systems where working conditions may reach up to 130°C or drop as low as -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 can be used in 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.
