FRP Polyurethane (PU) Composite Panel
FRP&PU composite panels are composed of Gel coated FRP skins on both sides of a PU (Polyurethane) core. Regular FRP skin thickness is 1.5mm, 2.0mm and 2.5mm. Total Panels thickness frequently used is 25mm, 30mm, and 50mm. Panel size within 2500x10000mm can be customized as per customers request.
Our FRP skin is made of unsaturated polyester resin and glass fiber, the polyurethane core used is B2-B1 class fire retardant foam core. The FRP skin is very smooth in glossy or matt finish at your request. We can also embed structure such as steel tubes or aluminum profile inside the panels to strengthen the panel or for installation purpose.
Some technical data of the FRP&PU composite panel.

1. Stable structure. The FRP PU sandwich panel is composited by high temperature polyurethane glue with stable structure and non deformation.
2. Water-proof and moisture-proof. The Polyurethane foam is a kind of hydrophobic material with 90% obturator rate which can prevent moisture and water.
3. Lightweight with hing strength
4. Temperature resistant
5. Low thermal insulation
