Foams & Core Materials

A 2 part liquid foam which when added together in equal parts will expand up to 25 times its original volume and set rigid. It is extremely buoyant, 1 cubic foot will support 27kg in water and will bond well to most materials. It should always be protected by a GRP skin because although closed cell and water proof when set. It will absorb water when crushed. 1kg of liquid foam = 1 cubic foot when expanded.

Rigid sheets of expanded closed cell foam available from 1" to 4" thick, which can easily be cut and shaped to make ribs or formers over which glassfibre can be laminated. Resin does not react with this foam.

A flexible polyethylene foam sheet which does not crush, easy to cut and does not react with resin. The foam bends which makes it ideal for creating ribs in hulls.

This core material is used to produce sandwich fibreglass panels in boatbuilding and industrial moulding. It has excellent chemical resistant, sound insulation properties and is resistant to delaminating.
