Fiber Glass Epoxy Sheet and Rod
We utilize electrical glass cloth impregnated with epoxy resin under heat and pressure to manufacture our fiber glass epoxy sheet and rod. This kind of reinforced thermoset is born with extraordinary mechanical strength and dielectric properties.
This plastic material is applicable for insulating parts used in electric motors and electronic appliances. Moreover, our fiber glass epoxy product is also capable of handling humid condition and insulating oil.
Strength
1. Oil resistant
2. Outstanding inertness to all kinds of solvents and acid chemicals
Application
1. Parts for chemical equipment and general machinery
2. Base plate, support and guard panel for electric generator
3. Insulating parts for transformer, inverter, electric motor, distribution box, fixture board material, clamp plate for molds, high and low voltage wiring closet, as well as packaging machine
4. Mechanical mold, fixture material for PCB (printed circuit board) and ICT (in-circuit test), as well as forming machine, drilling machine and base plate for grinding, etc.
