Fire Resistant UPGM203 Polyester Resin Fiberglass Plate Sheet

Made in China UPGM203 material with EN45545 and UL certificate

UPGM203 introduction 

UPGM203 Sheet also known as GPO-3, in NEMA grade we called it GPO-3 but in IEC grade we call it UPGM203 . Product composition of it is glass fiber and polyester resin . It is alkali-free fiberglass mat coated with unsaturated polyester resin as the basic material , then pressed under high temperature into rigid sheet as insulation sheet. It has good electrical property under high humidity and high mechanical property under medium temperature. In other way , it has fine fire retardant property and meet UL94-V0 , good arc resistance (arc resistance meet 184 second) and tracking resistance (CTI600) . It's widely used in the low voltage electrical industries such as making of insulating supports, bus bar supports and mounting panels in switch-gear , top cover and bottom cover in transformer .

UPGM203 features 

1.It is halogen free material , very few effect to human body .

2.Good impact resistance on mechanical and electrical

3.Good machining properties, it can be punched, drilled, machined and cutting .

4. UL certification

5. ROHS and REACH certified once a year

6.It is fire resistance material , it meet requirement of UL94 V-0 standard

7.With very nice Comparative Tracking Index , it meet CTI≥ 600

8.Excellent heat resistance ,temperature meet 155℃

9.Excellent arc resistance ,it can meet 184 second

UPGM203 Application 

With the development of the society and technology , more and more electrical equipment widely used in every field .

GPO-3 is also used in more and more electrical products such as UPS/inverter/Switchgear and etc.

We would like to share some field which GPO-3 material used as following :

1.Bus bar in Switchgear

2.Insulation support in low voltage inverter

3.Insulating sheet in uninterruptible power supply

4.Top and bottom cover in transformer

5.arc extinction in breaker

6.air gap in electric motor
