Polyester Glass

GPO3

GPO3 is a 'Class F' laminate material manufactured from alkali-free E-glass mat and polyester resin. Sheets are formed in a heated platen press under extremely high pressure.

The finished material exhibits good electrical insulation characteristics and low moisture absorption combined with excellent flexural strength.

Fire retardant with good arc and tracking resistance, GPO3 is ideal for use in most electrical applications.

Available in Red, Grey and White colours, GPO3 is suitable for a wide range of insulation applications that require high mechanical strength.

GPO3 can be supplied in sheet, channel or box section and can be cut or machined. For component/machined parts we recommend using our in-house CNC machining service as GPO3 is not easily machined.

For those wishing to machine GPO3 please note, the material is abrasive to normal woodworking or metalworking tools. Also, machinery can be affected by the dust thrown off during the machining process. The dust is abrasive and can affect control gear as well as moving parts. GPO3 should be machined in a dry and well ventilated area.
