Unsaturation polyester glass mat
laminated sheet (NEMA GPO3)
Properties
Unsaturation Polyester Glass Mat Laminated Sheet(UPGM203,
NEMA GPO3) is made of several layers glass mat
impregnated with unsaturation polyester resin by processing
under heat and pressure, the natural color is typically red
which has excellent arc and track resistance.
