UPGM 203 Thermoset Polyester Resin Sheet With Glass Mat Reinforcement

Thermost upgm 203 sheet(GPO3 sheet)that consits of polyester resin and glassmat reinforcement

Product Description:

UPGM 203 Thermoset Polyester Resin Sheet With Glass Mat Reinforcement 0
Thermost upgm 203 sheet(GPO3 sheet)consits of polyester resin and glassmat reinforcement a glass reinforced,Thermost upgm 203 sheet(GPO3 sheet)  is  thermoset insulation material. Thermost upgm 203 sheet(GPO3 sheet) has excellent electrical properties including flame, arc, and track resistance. Thermost upgm 203 sheet(GPO3 sheet) is widely used for electrical insulating applications. GPO3 is widely used in electric  power grid, new enrgy,rail wat traffic.

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℃
