Thermoplastic polyurethanes for automotive manufacturers

Paul Boughton

From high performance extrudable materials to protect ABS wiring systems to soft touch injection moulding solutions for cup holders and key fobs, thermoplastic polyurethanes (TPUs) from Huntsman are widely employed by car manufacturers and their specialist suppliers around the world.

Technologies from Huntsman on display at K2013, Dusseldorf, Germany, for the automotive industry will include:

For injection moulding applications:

IROGRAN A 70 E 4675 – a soft UV-stabilised, plasticiser-free polyester TPU with high bond strength for car keys and other over moilded parts
IROGRAN A 85 C 4002 – a TPU with high rebound resilience employed in door checks
IROGRAN A 92 E 4246 – a flexible material suitable for a variety of applications including plug and cable components.

For ABS cable jacketing:

IROGRAN A 95 P 5044 – a highly stable, oil-resistant material, ideal for automotive cabling applications including wires in ABS systems.

For cable protection tubes:

IROGRAN A 85 P 4441 – an extrudable TPU that can be easily manipulated to create tubes to protect wires employed in car electric management systems.

For seals: IROGRAN A 92 K 5031 DP – a good all round performer for automotive and other industrial seal applications where oil resistance and the ability to withstand temperature extremes are a must.

For non optical film and sheet projects:

IROGRAN CA117-200 – for car seat laminating applications
KRYSTALGRAN PN 3429-218 – for paint protection films.

For optical film and sheet applications, eg, panoramic roofs and security glazing for VIP cars:

KRYSTALFLEX PE399 – a high performance aliphatic polyether film that can be used to laminate glass, polycarbonate and acrylic substrates together for hybrid glazing and security applications in the automotive industry.

For automotive adhesive applications such as laminated door panels or floor carpets:

IROSTIC S 6148 – a TPU solution with a long open time, excellent hydrolysis resistance and green tack, and good heat resistance (for applications where heat activation isn’t desirable or possible).
