EN45545 GPO3 UPGM203 Fiberglass Laminated Sheet With CTI600

UL and EN45545 recognized GPO-3(UPGM203)laminated sheet with CTI600


GPO3 fiberglass reinforced polyester sheet was made of fiberglass and polyester resin , the fiberglass was impregnated in polyester resin and then press under the high temperature by press machines . This material has very nice fire resistance , low smoke and non-toxic. The material has recognized by EN45545/UL/ROHS/REACH .As we know , the rail traffic projects such ashigh-speed rail and metro requested this properties , they required fire resistance , low smoke and non-toxic if breaking out of fire when high-speed rail or metro running . Mentioned properties will save the lives of the people who are in the carriage . To avoid any mistake , the relevant project required EN45545 test report . It is very difficult to pass the test due to the high requirements
This material has been exporting to more 30 countries , so many of the customers are top500 , we are one of the most largest GPO3 manufacturers in China
