Osnabruck, Germany - Huntsman has developed a new thermoplastic polyurethane (TPU) that it says offers a broader temperature operating range than standard grades and is a good all-round performer in industrial applications where compromise is not an option.
Irogran A 92 K 5031 DP has been formulated to be extruded or injection moulded to create elastomer components for heavy-duty engineering equipment, engines and hydraulic systems where working temperatures may reach 130°C or drop as low as -40°C.
"In the production of flexible elastomeric parts, the most successful materials are those that offer infinite processing possibilities and performance scope alongside consistent quality," said Helmut Witt, new business development manager at Huntsman Polyurethanes, in a 20 Jan company statement.
The grade has high strength at room temperature, low compression set at 100°C and consistent form retention and stability up to 120°C.
Huntsman says these attributes make it practical 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.
Good anti-burst properties and resistance to long-term exposure to oils, hydrolysis, chemicals and abrasion also make it a reliable base material for hydraulic seals.
Witt said Huntsman developed a special technique to make the new grade, employing raw materials economically, and delivering optimised hard block products of an extremely reliable standard.
"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," he commented.
