Cooper Standard rolls out TPV hoses for electric vehicles

Northville, Michigan – Cooper Standard (CS) has introduced a lightweight alternative to traditional EPDM rubber hose used in thermal management systems of electrified vehicles (EVs).

The thermoplastic vulcanisate (TPV) products are said to perform like crosslinked rubber while offering thermoplastic processability without the need for material compounding or curing.

Other key selling points include weight savings of up to 40% compared to EPDM hoses and increased flexibility compared to thermoplastic tubes of similar size.

“Our TPV hoses also meet the needs of lower temperatures and system pressures that electric vehicles require,” added a CS release issued 11 Oct.

The TPV hoses from provide a smooth internal surface, resulting in a solution that minimizes the impact of pressure losses in a coolant system, continued the company.

The products, it said, “are flexible, but strong using a layer of reinforcing yarn for flexibility during installation and to allow dynamic movement of mating components.”

Also, the TPV hoses are said to connect to the vehicle through traditional EPDM hose connections, such as clamps, or special connector units.
