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
Feature of GPO-3 Sheet
It is the low smoke material , it will save the lives when breaking out of fire if it used in rail traffic .
It is the customized products can be machined as per client’s requirements .
It is the high strength of the insulation properties and mechanical property material
It is excellent Electrical Performance material with the arc resistance more than 180 seconds and CTI600
It is the green product and have already passed the recognized by RoHs and Reach.
It is very excellent on temperature , the temperature index of this materials is from -270 to 155 degree centigrade , it can adjust to very low and high temperature .
This material reach requirement of UL94-V0
