Product Description

Red UPGM 203 Fiberglass mat reforcement laminated sheet with highflexural strength GPO3 machined part

Product Introduction:

GPO3 is a special laminated material based on unsaturated polyester resin in connection with a reinforcement of glass mats and relevant chemical agent.




Electrical Insulation :All grades of GPO3 sheet have inherently good dielectrics. They are engineered to maximize the specific properties required for a wide range of electrical applications.


Flame Resistance :GPO3 sheet are UL-rated V-0. They belongs to halogen-free system that generates very low smoke and smoke toxicity in a fire situation.


Mechanical Strength :Our GPO3 sheet have stable mechanical strength wich won’t cracked when machining


Heat Resistance:Our GPO3 sheet have excellent property retention and dimensional stability at elevated temperatures. These laminates have UL temperature index ratings over 150℃



GPO3 are widely used in F-class electric motors,transformer,switchgear,circuit breakers and electrical equipments. UPGM can be moulded into all kinds of structure parts or profiles as per customer's special requirement.

Thickness range :0.5mm-60mm


Sheet Size:1000mm*1200mm and 1040mm*1230mm and 1230mm*2100mm
