Thermoplastic TPV and TPE Solutions for Electric Vehicle Seals, Gaskets, O-rings and Tubing
Electric vehicles (EVs) demand high-performance, lightweight, and durable materials for critical components such as battery packs, high-voltage connectors, fluid management systems, and thermal management parts. Thermoplastic elastomers (TPEs) including Santoprene® thermoplastic vulcanizates (TPVs) have emerged as the go-to material for these applications, offering flame retardancy, chemical resistance, and design flexibility.
At SantopSeal Rubber Corporation, we specialize in custom EV rubber and TPE components, including O-rings, gaskets, seals, tubing, custom extrusions and molded parts, providing U.S.-based manufacturing, prototyping, and technical support.

Why TPEs Are Essential in Electric Vehicles
EV designs compress high-voltage electronics, battery packs, and cooling systems into compact spaces. This introduces challenges such as heat accumulation, vibration, and fire risk. Santoprene TPV and other TPEs address these challenges with:
- Flame retardancy for under-hood and battery compartment components
- Chemical and thermal resistance to coolants, oils, and battery electrolytes
- Flexibility and durability for dynamic sealing applications
- Lightweight, recyclable materials for energy-efficient and sustainable EV production
Key EV Applications of TPV in Electric Vehicle
- Battery System Seals and Gaskets
- High-voltage battery enclosures require robust sealing to prevent moisture ingress and protect electronics.
- TPV gaskets and seals provide reliable compression set resistance, chemical stability, and thermal endurance.
- Used in module covers, interconnect seals, and battery housing lids.
- Cooling System Tubing and Hoses
- Battery and power electronics cooling systems rely on flexible, chemical-resistant hoses.
- Santoprene® TPV tubing withstands high temperatures and coolant chemicals while maintaining flexibility for tight routing.
- Applications include battery coolant lines, motor cooling circuits, and inverter fluid transport.
- High-Voltage Connector and Wire Insulation
- High-voltage bus bars, cables, and connectors require insulation that is flame-retardant and mechanically resilient.
- TPE jackets and insulation layers made from Santoprene® ensure safety, longevity, and compliance with EV electrical standards.
- O-Rings, Seals, and Custom Extrusions
- Critical for hydraulic, pneumatic, and coolant systems, dynamic and static O-rings prevent leaks and maintain system integrity.
- Custom extruded profiles fit unique geometries in battery packs, motors, and fluid manifolds.
- Consumer and Interior Components
- Flexible and durable TPEs are ideal for interior trims, cable grommets, and sealing interfaces in EV cabins.
- Combines chemical resistance, flexibility, and aesthetic finish for high-quality finishes.
