Stronger Automotive Hoses
Using knitted or braided Kevlar® fibre to reinforce radiator, transmission, and turbocharger automotive hoses helps make them light and strong.
This is because Kevlar® is not only stronger than other materials typically used in high-pressure hoses, but has excellent thermal stability and chemical resistance too.
Kevlar® aramid fibre is made into a continuous-filament yarn available in a broad range of decitex. It is often woven into fabric and twisted and plied into cords.
The inherent thermal resistance of DuPont™ Nomex® makes it ideal for high-temperature applications in automotive hoses.
Sheet structures made of DuPont™ Nomex® fibre are used for under-the-bonnet applications including flexible, high-temperature hoses – for instance, the ones that feed hot air to inlet manifolds and the turbocharger hoses.
DUPONT PRODUCTS & SERVICES
DuPont™ Kevlar® fibers are used to help provide strength, flexibility, and lightweight protection in everything from yarns and woven ballistic fabrics to ropes and apparel.
INFORMATION & IDEAS
DuPont was the first company to commercialize a PA1010 polymer for the automotive market. Zytel® RSLC 1610 is a PA1010 specifically formulated to provide better thermal properties and chemical resistance to biodiesel fuel, compared with the materials it replaced.
