Manufacturers of lay flat hoses for high pressure industrial and municipal applications now have a new thermoplastic polyurethane (TPU) at their disposal – thanks to global chemical company Huntsman. IROGRAN® A 85 P 4394 HR TPU is a highly versatile, durable elastomer that can be used to create a variety of hoses, including those used by firefighters to bring blazes under control.
Designed for use via the “extrusion through-the-weave” process, IROGRAN® A 85 P 4394 HR TPU is the latest addition to a well-established family of elastomer products, which are widely used in hose applications and renowned for their wear performance and hydrolytic and microbial resistance.
Developed by Huntsman’s Specialty Elastomers experts, IROGRAN® A 85 P 4394 HR TPU has a low melt volume-flow rate (MVR), which increases the overall tensile strength of the material once it has been extruded. With greater tensile strength, hoses that are made using IROGRAN® A 85 P 4394 HR TPU are less likely to fail in the field and are better able to withstand high pressure conditions. In the case of fire hoses that could be in the region of 8 to 20 bar (800 to 2000 kPa; 116 to 290 psi).
Trent Shidaker, Global Marketing Director, Elastomers at Huntsman, said: “Developed in close cooperation with several of our hose customers, this new TPU grade offers significant improvements over previous generation technologies when it comes to durability, production efficiency and reducing manufacturing waste. Less likely to break once in situ, extruded films made from IROGRAN® A 85 P 4394 HR TPU can help increase the longevity of hoses employed in mission critical applications.”
IROGRAN® A 85 P 4394 HR TPU is based on a Huntsman elastomer chemistry that dates back to 2004, when the flagship product in this innovative range of materials was first developed. IROGRAN® A 85 P 4394 HR TPU is made at the Huntsman Polyurethanes manufacturing facility in Ringwood, Illinois.
