Automotive Applications
The automotive industry demands sealing materials that can endure extreme thermal cycles, aggressive fluids, dynamic motion, and long service life. From internal combustion powertrains to electrified platforms, our rubber compounds are engineered to maintain performance under elevated temperatures, high pressures, and continuous vibration.
Garlast partners with OEMs and Tier suppliers worldwide to deliver production-ready seals, gaskets, and custom components that reduce emissions, enhance efficiency, and support lighter, more compact system architectures.
Key Requirements:
- Fuel, oil, coolant, and transmission fluid resistance
- Wide temperature capability (-40°C to +180°C)
- Low compression set and long-term sealing force
- Compatibility with biofuels, EV coolants, and e-fluids
- Low permeability to meet emissions regulations
- Noise, vibration, and harshness (NVH) mitigation
