Shop for Expanded PVC Sheet Marineboard. StreamLite™ is a marine-grade expanded PVC sheet from the Seaboard® line of materials specifically for marine, RV, and outdoor use. Although a light-density sheet, it has good stiffness and impact resistance, and is easy to form, cut, and fabricate for light-duty applications. Available in white or black in a satin smooth finish, these sheets have a small cell structure for excellent screw, nail, and staple retention and looks great when finished with traditional tools. Easy to glue, paint, and laminate. StreamLite™ is UL 94 V-0, ASTM E-84, NFPA-255, and RoHS Compliant, making it a viable material option for non-load bearing wood replacements, cabinetry, marine seat backs, shutters, instrumentational panels/consoles, and case goods. Custom cuts and cut-to-size pieces. Stocked materials typically ship in 2-5 business days. Can’t find what you need? Get a quote.
