Backed by a reliable supply chain combined with robust technical support, DuPont solutions are specified for passenger, commercial, and off-road vehicles to manage fluids such as oil, fuel, coolant, and refrigerant.
As temperatures rise under the hood, our materials for in-tank and external fuel conveying applications facilitate:
Performance advantages include:
Typical applications include:
For internal combustion engines, hybrid, or full-electric vehicle thermal management systems, DuPont™ Zytel® long-chain polyamides (PA612, PA610, and PA1010) exhibit excellent hydrolysis resistance at elevated temperatures. They enable high flexibility for mono- or multi-layer tubing when used with DuPont™ Multiflex® TPO or other polyolefins such as Bynel™ PP (Bynel™ is a trademark of Dow or an affiliated company of Dow) as alternatives to metal pipes and/or ethylene propylene diene monomer (EPDM) cooling lines.
DuPont™ Vamac® AEM is recognized as a proven elastomer solution for high-temperature and flexible oil cooler hoses compatible with different types of oils including new EV fluids.
Quick connectors made of reinforced materials such as Zytel® PA66, Zytel® HTN PPA, or Zytel® LCPA complete the fluid management lines and offer an integrated full-plastic solution.
