PVC (Vinyl) Foam is the last foam variety that we will explore in our blog series "Foams for Low Clamping Force Seals".  PVC Foam is a lightweight closed-cell foam material.  It is often used for sealing out water, dirt and air.  It resists weathering and is often laminated with adhesive to create a dynamic foam tape. 


Features and Benefits of PVC (Vinyl) Foam

  • Closed cell structure seals out air, moisture, light and dust when compressed at least 30%
  • UV resistant and resists most chemicals, acids and solvents
  • Service temperature range of -40°F to 200°F
  • Inherently fire resistant


The categories of foam that we have written about in this blog series barely scratch the surface of the differences between the many foam options for low clamping force seals.  For more guidance in determining a sponge or foam for your application, please contact Marian.
