- Specifications
- 11# PVC Foam is a medium density, closed-cell foam. This provides an excellent combination of flexibility and conformability with strength an wear resistance.
- Characteristics of 11# 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.
