All plastics have oil or plasticizers in them. Usually these oils are free to move and will migrate to the surface, top or bottom. When they get to the surface and get washed away, the plastic dries out and becomes brittle. If the surface is the bottom and the oils meet the glue they can compromise the bond. The formulation of pvc synthetic teak decking keeps the oils locked in place so it will retain its adhesion, stain resistance and flexibility throughout its life.
No,PVC synthetic teak decking does not stain from these. Please see our video to the right that shows us testing PVC synthetic teak decking for resistance to staining, chemicals, heat and impact.
