How Is LSR Used in the Automotive Industry?

04/28/2026

What Automotive Components Are Commonly Made with LSR?

LSR is widely used for engine seals, connector grommets, lighting lenses, and HVAC components due to its ability to withstand high temperatures and resist oils and fuels. Its flexibility allows for effective vibration dampening in sensitive electronic modules. The material's clarity and UV resistance make it ideal for exterior lighting applications.

Why Is LSR Preferred for Under-the-Hood Applications?

Under-the-hood environments expose components to extreme heat, moisture, and chemical exposure. LSR's thermal stability and chemical resistance ensure long-term reliability in such harsh conditions. Its ability to maintain flexibility at low temperatures also supports cold-weather vehicle performance and easier installation.

How Does LSR Support Electric Vehicle (EV) Development?

In EVs, LSR is used for battery encapsulation, charging port seals, and cable harnesses due to its excellent electrical insulation properties. It also helps manage thermal dynamics in battery packs. Its flame retardancy and low smoke emission during combustion enhance passenger safety in case of accidents.

What Role Does LSR Play in Sensor and Connector Protection?

Modern vehicles rely heavily on sensors and electronic connectors that must be protected from moisture, dust, and vibration. LSR's conformal molding capability allows it to encapsulate delicate components tightly, providing IP-rated protection. Its transparency can be engineered for optical sensors, while its flexibility accommodates thermal expansion.
