Ultralon foam

We offer U-Dek solutions

U-Dek is a closed cell foam with a high grip brushed surface, that is non-absorbing and easy to clean. Because of its lightweight, durable and high grip properties, U-Dek is widely used on motor and sailing yachts as well as race yachts, speed and sportboats, water scooters etc.

Sheets are available with or without 3M™ marine-grade, pressure-sensitive adhesive backing for easy peel-and-stick installation.

U-Dek anti-skid deck tread offers a stylish, easy to maintain alternative to moulded-in anti-skid or paint-on textures for traction in wet areas. Improving comfort and safety. Available in different styles and colours, U-Dek can be customised to suit individual styles.

Ultralon foam

Ultralon closed cell chemically cross-linked foams are manufactured from polyethylene (PE), ethylvinyl-acetate copolymers (EVA) or a high-tech blended copolymer. The fine cell structure gives minimal water absorption, a high buoyancy rating and excellent chemical resistance.

Ultralon foams are produced in moulded block form and can be trimmed to size and thickness. They are easily processed, using standard foam-processing machinery. No chlorofluorocarbon (CFC) product or derivatives are used, and no organic fillers are added to foams.

Ultralon anti-slip, closed-cell foam deck treads offer a hard wearing, easy to maintain alternative to moulded in anti-slip or paint-on textures for traction in wet areas, improving your comfort and safety. Ultralon foams provide protection for boat surfaces, especially in high traffic areas.

U-Dek 140

A dual layer foam decking that provides protection for boat surfaces. The traditional teak-look and custom patterns are achieved by CNC routering through the top layer of foam exposing the layer underneath. Edges are beveled to create a high-quality finish.

Custom patterns, logos, trim strips and boat names can be integrated into the design. U-Dek Laminated is widely used in the cockpits of race-sailing yachts for its anti-skid properties, while it can be found as a standard feature on swim platforms of OEM boat builders around the globe.

All U-Dek Laminated decking comes formulated with or without a 3M™ marine-grade, pressure-sensitive adhesive backing for easy peel-and-stick installation.

U-Dek 190

U-Dek 190 has a higher density meaning more durable and less susceptible to light amplification, improved heat tolerance, less shrinkage and a superior foam decking solution. Similar hardness to the existing well proven U Dek 140 for ease of machining and comfort.

The increased tensile strength, higher elongation, and tear strength means the highest performing foam for your customers decks.
