EpoxyEpoxy glass laminate
Epoxy is a glass laminate made by impregnating glass cloth with epoxy resin, then heating and pressing it in a multi-stage high-pressure press. Its uniform, hard surface keeps burrs to a minimum. It is lighter than metals yet mechanically strong, and its low water absorption and high surface resistance make it a good insulating reinforcement material.
- Sheet thickness
- 0.5~50mm
- Rod diameter
- Φ5~90mm
Features
Excellent mechanical properties
Epoxy resin on a glass fiber base gives a material lighter than metals but mechanically strong enough for industrial structures.
Suited to insulating reinforcement
Low water absorption and high surface resistance make it a good insulating reinforcement.
Good electrical properties
Good electrical properties and machinability give it a wide range of uses.
Good machinability
Low water absorption keeps warping in storage low, and thin sheets punch well.
Dimensional stability
Resists heat and holds its shape well.

Frequently asked questions
What sizes of epoxy sheet and rod are available?
Sheet comes in jade green and yellow, 0.5, 0.8, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 15, 20, 25, 30, 35, 40, 50 mm thick. Rod comes in jade green, Φ5, 8, 10, 12, 15, 18, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 85, 90 mm.
Can epoxy be used for electrical insulation?
Yes. Low water absorption and high surface resistance make it a good insulating reinforcement, and it is used in transformers, switchboards and electronic circuit boards.
Does epoxy sheet warp in storage?
Its low water absorption keeps warping in storage low. Thin sheets also punch well.
Can epoxy replace metal in structural parts?
Epoxy glass laminate is lighter than metals but mechanically strong, so it can be used in industrial structures.
