TP450 is a soft and flexible open cell polyurethane foam, impregnated with an acrylic based, UV stabilised resin with large joint size tolerance for large movement applications. The resin is water repellent and contains a fire retardant. TP450 has a self-adhesive side to aid initial location and is easy to apply in any weather. Additionally, TP450 has both thermal and acoustic insulation properties.
