<p>Plate that is based on a 2-component synthetic foam, has a coating layer on both sides; >=1 of the coating layer consists of a rigid, flat synthetic material based on unsatd. polyesters and reinforced with glass fibres; this layer is 0.5-2 mm thick and is bonded directly to the foam. The plate is mechanically strong and resists distortion. Prodn. is simple. Warping does not occur during prodn. The plates can be used as wall and roof elements, e.g. for house, caravans and animal stalls.</p> |
