New additions to the Lexan line of polycarbonate (PC) materials include Lexan CFR (clearflame- retardant) copolymer and three Lexan LUX resin grades for LED applications such as light guides and lenses.
The CFR copolymer complies with the UL 94 V-0 standard down to 1.0 mm and the UL 94 5VA standard at 3.0 mm. The transparent resin provides a nonbrominated, nonchlorinated, nonphosphate, non-Teflon FR that complies with major environmental protocols.
The Lexan LUX resin portfolio includes three new transparent grades, as well as three others designed for covers of LED bulbs and tubes.
The new resins —Lexan LUX2110T, LUX2010T, and LUX2910T — use technology that offers improved initial color, color stability, and light transmission during heat aging versus standard PC. These resins are engineered using a technologically advanced process, resulting in high-purity resins that provide significantly improved light transmission as molded and after heat aging. These grades retain more than 98% of initial light transmission when exposed to a temperature of 130°C for more than 5,000 hr. At more typical heat exposure — in the range of 90 to 110°C — the transmission retained is even higher.
