High Flexural Strength UPGM 203 Red Fiberglass Laminated Sheet

UPGM203 red firbergalss laminate Sheets High Performance with Good Flexural Strength

Product Introduction:

UPGM203 sheet or related products are consists of unsaturated polyester and fiberglass mat ,UPGM203 sheet offer a superior combination of electrical and mechanical properties such as dielect ric strength ,flame resistance,arc and track resistance,high-flexural and high-impact strength.

our laminates also have superior consistency in thickness, punchability and property control. Add a high degree of quality and cost-ffectiveness.

These sheets are fiberglass reinforced thermoset polyester,They will not melt under heat and have excellent overall electrical properties .all grades are UL Recognized.



Good electrical performance,under high temperature,good performance for anti leakage of electronic


Arc-resistance could reach more than 180℃


Flame retardant grade could reach UL94 V-0 termal endurance class could reach Fgrade(more than 160℃)


It is the advance retardance, anti impact,and anti corrosion materail in recent years

UPGM203 with high peformance tensile used in Transformer


High Flexural Strength UPGM 203 Red Fiberglass Laminated Sheet 0

The electric reactor is also called the inductor ,after the electric reactor is energized, the magnetic field can be generated in a certain space range which plays a protective role in the power transmission and distribution.The transformer utilize the electromagnetic induction to change the voltage of the alternating current, and it acts as an energy conversion process.
