    • ELYT: sheets with TEDLAR polyvinyl fluoride film, highly U.V-ray resistant. and to sheet surface yellowing.
    • ELYX: sheets with MELINEX polyester, resistant to atmospheric abrasion and early fiberglass surfacing.
    • ELYTOP K: the ELYTOP K sheets, are made of CRISTAL polyester resin, U.V.stabilised, fiberglass reinforced, protected on both sides with selected resins coating, hot bonded during lamination (gelcoat). This protection ensures good structural and functional capacity over time.
    • ELYK: Sheets made of Cristal polyster resins with meta-acrylic polymers added. Their main property is high transparency which allows light to pass almost like glass.
    • ELYLUX K: lastre sheets made of Cristal polyester resin, U.V.stabilised, fiberglass reinforced and with MELINEX 389 film protection on both surfaces. This protection resists over time and maintains good functional and aesthetic properties.
      Questa protezione permette notevole resistenza nel tempo mantenendo buone caratteristiche funzionali ed estetiche.

The surface of ELYPLAST 494-496-497 precurved sheets is manufactured with a MELINEX 301 polyester film protection. Standard precurved sheets C 177 - C 146 with variable radiuses (9-17 m) are not supplied with surface protection. On request , precurved sheets can be manufactured with abrasion-proof MELINEX 301; U.V. resistant MELINEX 389 and anti-ageing TEDLAR protections. The TEDLAR protection ensures greater sheet resistance to U.V ray degradation and to other corrosive elements found in the atmosphere, making sure that 80% of the initial light transmission is maintained.
