Marine grade HDPE is formulated to meet the specific requirements of marine and other outdoor environments. Special post production treatment enhances its ability to withstand the effects of salt water, moisture, and direct sunlight. Like regular HDPE, this material exhibits high impact strength as well as excellent tensile strength, energy absorption, abrasion resistance, and resistance to stress cracks. In addition to its resistance to marine and other outdoor conditions, Marine grade HDPE has a decorative, textured surface that does not show wear, dirt, or scratches and is available in a variety of colors. Marine grade HDPE is manufactured as a continuous extrusion; therefore, it is guaranteed not to delaminate during the service-life of the end-product. It also meets FDA approval for direct food contact.
High Density Polyethylene Marine Board is specially formulated to withstand the rigors of harsh outdoor marine environments. It is UV-stabilized to resist damage and retain its beauty, even after years of direct sunlight. Increasingly, Marine Board is replacing wood and laminates in boating applications. It does not splinter, crack, delaminate, rot, swell or absorb water like traditional materials. Even under heavy foot traffic on yacht decks, it remains virtually maintenance-free.
