PVC (Vinyl) Foam is the last foam variety that we will explore in our blog series "Foams for Low Clamping Force Seals".  Polyvinyl Chloride (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 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

What are the Benefits of PVC (Vinyl) Foam?

  • Excellent performance across a full range of temperatures
  • A versatile material that can be used across a wide range of industrial applications
  • Cushions against shock and vibration
  • Effectively seals out light, air, moisture, and dust

Common Gasket Applications for PVC Vinyl Foam

As stated above, when compressed at 30% this material acts as a highly effective sealing gasket across many applications and industries. Marian has the capabilities to die-cut vinyl foam into custom gaskets for virtually any shape or size. In addition, Marian can laminate PSA to a PVC Vinyl foam to create a single or double-sided tape.
