FREVA™ is an innovative eco-friendly fireproof material made of ethylene-vinyl acetate(EVA) copolymer and halogen-free fire retardants. Combining USI’s two new core technologies - powder surface modification technology and chemical formulating technology - FREVA™ exhibits excellent fire retardancy and smoke suppression performance.
FREVA™ could be extruded by itself or laminated on different substrates, such as fabrics, mashes, to produce sheet products. As a fire retardant sheet, strong chemical-bond network of FREVA™ makes it very sturdy. When exposed to fire, special inorganic fire retardant in FREVA™ will release water vapor to cool down the surface temperature of material. Moreover, at high temperatures, FREVA™ will form an incombustible char layer under a very short time to prevent further burning to achieve extreme fire retardancy.
