- Specifications
- 8# PVC Foam is a light density, closed-cell foam. This economical, general purpose foam tape is used in Applications requiring positive seals on irregular surfaces or when flex and conformity to seal tight radius curves are critical considerations.
- Characteristics of 8# PVC Foam include the ability to make a long life sea against air, moisture, light and dust when compressed 30% or more.
- Absorbs shocks, cushions, deadens sound and eliminates excess vibration.
- Inherently resistant to fire, ultraviolet rays, most chemicals, acids and solvents.
