Specifically designed to meet marine and outdoor environment conditions, marine grade HDPE boards provide sustainable surfaces without risk of splintering, rotting, or swelling. All marine grade HDPE boards from Emco Plastics undergo special postproduction treatments to enhance their ability to withstand the harsh effects of salt water, extended periods of moisture, and direct sunlight.
HDPE marine boards are easily able to be fabricated into various outdoor components, including deck components, cabinets and countertops, doors and doorframes, swimming pool and dive platforms, and more. Emco Industrial Plastics offers cut-to-size HDPE marine boards for virtually all marine applications.
This UV stabilized material has great scratch and impact resistance, and stiffness yet is easy to fabricate and machine for the most demanding applications. It is ideal for outdoor cabinetry, furniture, signage, and recreational area applications. Seaboard HDPE has no moisture absorption, great scratch resistance and is FDA and USDA compliant.
Top Applications for Seaboard™ HDPE:
Key Material Benefits for Seaboard™ HDPE:
Seaboard™ LITE HDPE is produced utilizing co-extrusion technology that allows for solid outer surfaces with a foamed core. The core is produced with a closed cell structure that eliminates propagation of moisture within the core. It weighs 1/3 less than solid HDPE representing an opportunity for cost savings.
Top Applications:
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.
HDPE marine boards are manufactured for various uses and brands, Emco Industrial Plastics is proud to offer materials for HDPE boards used by various manufacturers, including:
