Gaskets, Seals, and Barriers for Electric Vehicles

Our manufactured products can be found in many different EV applications, but particularly in the battery, perhaps the single most demanding component in an electric vehicle. Through long-term partnerships with leading raw material manufacturers, we have access to the most cutting-edge materials at very competitive prices.

We fabricate:

  • Fire block gaskets
  • High-temp barriers
  • Vibration damping seals
  • Electric and thermal insulator gaskets
  • Foam vibration pads (key to reducing vibration from lithium ion batteries)
  • Mica thermal barriers
  • Environmental seal gaskets to protect battery cases
  • Vent seals and pressure release vents

The Most Suitable Techniques for Every Component

In electric vehicles, battery packs in vehicles are placed inside panels with upper and lower housing. Gaskets or seals are used to separate these sections and prevent particles and liquids from leaking into these housing sections. As with hybrid vehicles, electric vehicle battery systems are extremely sensitive to temperature changes, so these gaskets and barriers fulfill critical functions in controlling heat, as well as containing gas and liquids, and minimizing vibration and noise.

We have a range of fabrication techniques available, from extrusion to molding, and die cutting. Our sales engineers guide you through the selection of an almost limitless number of choices to find the one most appropriate — both performance-wise and price-wise — for your application. SMI in-house capabilities mean our experts can specify, design, and manufacture everything on the site, so our clients know they’re getting the right material for the functionality, as well as cost savings and exceptional quality control.
