Overview
Synthetic rubbers are pivotal in the evolution of electric vehicles (EVs), addressing challenges like thermal management and noise reduction. For example, styrene-butadiene rubber (SBR) with nanoscale silica reinforcement is now used in EV tires to enhance rolling resistance reduction by 15%, directly improving energy efficiency. Additionally, ethylene propylene diene monomer (EPDM) is employed in battery pack seals, offering superior vibration damping and thermal stability up to 150°C.
Key Applications
lTire Compounding: Hybrid SBR/NR blends reduce weight while maintaining grip on wet surfaces.
lBattery Components: Fluoroelastomers (FKM) in sealing gaskets prevent electrolyte leakage in high-voltage systems.
lInterior Noise Control: Polyurethane (PU)-based rubber dampers absorb road noise, enhancing cabin comfort.
