Using Rubber/PVC Materials for Gaskets


If you are looking for a cost effective material for your next gasket project, rubber/PVC materials are some of the best options on the market today. With great durability in situations where pressures and temperatures are low, you can expect your rubber/PVC gaskets to perform for an extended period of time. Here are just a few types of rubber/PVC materials that are commonly used and their benefits for your next gasket project:

  • SBR or Red Rubber. SBR or Red Rubber can be used in situations where the temperature varies from a freezing -20 degrees to 150 degrees. This material is offered in sheets of 1/32” to ¼”, SBR is durable when exposed to air, hot or cold water.
  • Natural rubber or pure gum materials. Natural rubber is one of the best options when faced with acids, organic salts and alkalis during use. This material stays soft for the duration of its use and can withstand temperatures of -20 to 140 degrees. These materials come in thickness of 1/32” to 1” for a wide range of uses.
  • Silicone is a high temperature option for applications where temperatures up to 400 degrees are possible. It stays soft and comes in thicknesses of 1/32” to ¼”. One of the most commonly used materials, silicone is versatile and can be molded to a wide variety of gasket shapes.
  • Vinyl materials. Vinyl is good for gasket applications that are exposed to changes in weather and the possibility of abrasion or rubbing against other parts during use. With a more limited temperature range of 20 degrees to 160 degrees than other materials, vinyl comes in thicknesses of 1/16” to 1/4” and resists water and oxidizing chemicals.

As you can see, there are many rubber/PVC materials that may work for your next gasket application. Call Gasko today to speak with one of our engineering staff on your specifications and our rapid prototyping service to use with rubber/PVC materials. Call now!
