Seaboard is a high density polyethylene sheet formulated to meet the requirements of marine and other outdoor environments. It is available from AllPlastics .

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. It is guaranteed not to delaminate during the service life of the end-product.

In addition to this high degree of stability, it offers good flexibility and toughness as well as good dielectric properties. UV stabilised Seaboard sheets meet FDA requirements for use in applications where they may come in contact with food.
