NON OUTGASSING PVC FOAM FOR RV PANELS

View:6225/06/2019  

About the PVC foam core outgassing.

Yes , it occurs because foams like PVC contain gas under pressure in closed cell, outgassing can occur over time.

When the gas escapes from the closed cells and migrates to voids or unbonded areas in the laminate.

In some instances, outgassing has been blamed for delaminations and blistering in marine construction, especially in parts made at elevated cure temperatures with epoxy resin systems or finished in dark colors.

But core experts contend the problem is caused primarily by improper laminating technique and poor skin-to-core bond. We can offer the "stabilized" PVC foam products that minimize this problem.
