Arc Resistant UPGM203 Polyester Glass Fiber Laminate Sheet
What is UPGM203 sheet ?
As we known UPGM203 laminate sheet is also called GPO-3, it is alkali-free fiberglass mat dipped into unsaturated polyester resin and added relevant filling material as the basic material pressed under high temperature PRESS into rigid panel as insulating material. It has good electrical property under high humidity and high mechanical property by medium temperature, quite nice fire retardant property, good arc resistance and tracking resistance. It's widely used in the low&medium voltage electrical industries such as making of phase and end barriers, insulating supports, bus bar supports and mounting panels in switch-gear and other types of electrical apparatus.
This material have been done the test in liquid helium approximate to -270℃, but it still has very nice strength on mechanical properties .
What is product feature of UPGM203 sheet ?
Electrical Insulation: GPO3 has good electrical property under high humidity and high mechanical property, fire retardant property, good arc resistance and tracking resistance.
Mechanical Strength: It can be machined, punched, drilled, milled, sawn, sanded, sheared or routed. Assembly by bonding, metal screws or rivets are also possible.
Environmental protection : this material is green product , it meet requirements of ROHS and Reach
