| Two different models available; 1. Standard cross-linked version means good shear resistance and high elongation • Main applications in naval construction, wind energy, industry... * Main advantages: • doesn't contain chlorine. • Finer cell structure (in comparison with PVC) means lower resin absorption. • Sandwich construction using STRUCT-CORE is lighter than PVC one. • High mechanical adherence due the chemical reaction of the resins with the polyurethane structure of the core material. 2. Fl Ml version means no toxic or dense smoke emission and low flammability ■ Main applications in public areas, vessels, train and aircraft construction. Or military uses. ■ Main advantages: • doesn't contain chlorine, • cross-linked foam, higher compression strength • unique Fl class 1 AFNOR approved in the market. Means no toxic and dense smoke (main cause of death in case of fire event is the asphyxia produced by smoke and gases). • Ml means no flame propagation, AFNOR approved. • FAR classified (for aeronautical). • ISO classified. • Good lamination even when using aluminium, wood or GRP. • Thermal isolation (low thermal conductivity: 0.028-0.030 W/mK.). • Acoustic isolation due its closed cell . • Major shear resistance than PET (Poly-Ethyiene-Terephtalate). |
