SEABOARD FROM SAN DIEGO PLASTICS

Seaboard is a high density polyethylene sheet formulated to meet the specific requirements of marine and other outdoor environments. In addition, special post-production treatment enhances its ability to withstand the effects of salt water, moisture and direct sunlight. Seaboard is manufactured as a continuous extrusion. It is not press laminated. Thus, it is unconditionally guaranteed not to delaminate during the service life of the end-product.
