PROMARINE®-450
................................................................................................................................................................................................................

PROMARINE®-450 is a non-combustible autoclaved Matrix Engineered Mineral Boards panel, reinforced with selected minerals and fibres and has a nominal dry density of 450kg/m³.

It is formulated without inorganic fibres and does not contain formaldehyde. The board is off-white in colour and has a smooth sanded surface on one face with a lightly textured reverse face.The board can easily be finished with High pressure laminates. It is resistant to the effects of moisture and will not physically deteriorate when used in damp or humid conditions.

The combination of moisture resistance, mechanical strength and fire protection cannot be matched by boards using other binder systems. The board is rigid and robust. It is easy to handle and can be worked with normal woodworking tools.

PROMARINE®-450 has been manufactured at the Promat Glasgow site for years. A truly international market leader, PROMARINE®-450 has been supplied to almost every major shipyard in the world and istalled on most types of sea-going vessels and offshore platforms.
