UL94-V0 GPO3 UPGM203 Halogen Free Laminated Board Sheets

Red GPO3(UPGM203) laminated sheet/halogen-free material meet UL94-V0 rating for fire resistance


Product Introduction:

GPO-3 material with red and white color for conventional stock , actually , the color can be custom-made if the quantity is big enough .GPO-3 material was made of polyester resin , glass fiber mat and inorganic material which called aluminium hydroxide. The actions of aluminium hydroxide is fire resistance , it will meet UL94-V0 when the thickness more than 3mm under normal conditions and no need filling any halogen material . This material has the very excellent machining properties , it can be cut into smaller sheet , grinded surface , drilled the holes and punched by reciprocating saw , CNC (CNC engraving machines) and punching machines . It can be machined into complex assembly parts by every machines according to the drawings from clients , that is means it is the customized product .


To meet the requirement from Europe and America ,the material has ROHS/REACH/UL/SGS and other requirements , it has been exporting to more than 30 countries all over the world , some of clients are the top500 in the world .

Feature of product

1. It has excellent machining properties and easily machined by CNC and cutting machine .

2. It is the green material with limited effect to the environmental when running in the equipment

3. It is the halogen free material and meet latest ROHS and Reach requirement and no effect to the human bodies when touching it .

4. It is the customized products can be machined as per client’s requirements .

5. It is the low smoke material , it will save the lives when breaking out of fire if it used in rail traffic .

6. Temperature index of this materials is from -270 to 155 degree centigrade , it can adjust to low and high temperature

Application of material

GPO-3 materials are more and more widely used in electrical industry , GPO-3 laminated sheet and machined parts are application to so many electric equipment , such as transformers , switchgears , reactor , inverter as the insulation sheet and support . it has very excellent machining properties and can meet iso2768-M class tolerance standard if machined by CNC.

As we know , with the technology development , the equipment request the thickness tolerance and machining tolerance smaller and smaller . So many parts with smaller tolerance on machining and thickness , such as air gas sheet and washer sheet , both of them are very important in transformer , it will reduce the noise when running if the air gap and washer sheet required the small tolerance .
