GPO3(UPGM203) with thickness range from 0.5mm-60mm , color can be custom made
The composite of GPO-3 laminated sheet are fiberglass and polyester resin and aluminium hydroxide material , then press under the high temperature & pressure by machine.
Currently , the major color of the sheets are red & white , however , the color can be custom made if needed .
For the sheet size , if the thickness less than 4mm , length and width will be 1200x1000mm ; if the thickness more than 4mm , length and width will be 2100x1230mm or 1230*1040mm . This material with excellent properties for machining , so the sheets can be easily machined by CNC such as milling , drilling and cutting , it can be machined into multiaspect , so complex parts can be machined by this material , if the drawings be sharing to us . In other way , the material with full certificates in the industry . We are the GPO-3 material manufacturer , full sheet and machined parts can be supplied to customers all over the world . The customers include so many Top500 in the world .
Feature of the material
The material with high strength , the tensile strength can reach to more than 160MPA according to IEC test standard .
The material has full set of every test reports in this industry .
It is meets requirements of environmental protection from EU, it has been recognized by latest revision RoHs and Reach.
It is can be customized , because the material can be machined as per client’s requipments , machined by CNC with very high accuracy class .
Running temperature range is very widely for the material , the temperature index of this materials is from -270 to 155 degree centigrade , it will adjust to very low and high temperature when operating.
It has the advantages on low smoke material and halogen free which is more safety when running in the assembly occupancies such as metro , high speech train etc..

Application of material
GPO-3 (UPGM203) laminated sheet and machined parts are application to Switch cabinet/transformers/breaker in rail traffic , such as metro , CRH train , high speed rail etc. most of them are used as the insulation support , insulation sheet , bus-bar clamp and cover plate in transformer ,Switch cabinet for it has very excellent properties on absorption resistance , electrical and mechanical . The most important is good arc resistance performance , as we known , arc will caused its carbonized , the carbonate is semiconductor , so if it hasn’t property of arc resistance , the electrical will be broken . Further more , the materials with the advantages with low smoke , non-poisonous , halogen free and good fire resistance with EN45545 certificate , so it is the safe material and will be more and more widely used in every industry .
