BakeliteBakelite sheet
Bakelite is a thermosetting resin based on fillers, lubricants and curing agents. It is cost-effective, easy to mold and versatile, and combines heat, solvent and chemical resistance. It comes as general (paper-based) Bakelite and fabric Bakelite, which has fabric inside the sheet; the choice depends on the application and operating environment.
- Flammability
- UL94 HB, V-0
- Sheet thickness
- 0.5~50mm
- Rod diameter
- Φ6~150mm
Features
Excellent electrical insulation
Insulates well enough to be used as an insulator.
Flexural strength and heat resistance
High flexural strength and heat resistance suit it to mechanical, electrical and electronic parts.
Moisture resistance
Good moisture resistance means little warping in storage and good punchability at low temperatures.
Flame retardant to UL94 HB and V-0
Flame-retardant products approved to UL94 HB and V-0.

Frequently asked questions
What is the difference between general and fabric Bakelite?
Fabric Bakelite has fabric inside the sheet; general (paper-based) Bakelite does not. Choose by application and operating environment. Fabric Bakelite sheet comes in 0.5, 0.8, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 25, 30, 35, 40, 45 mm.
What sizes of Bakelite sheet and rod are available?
Yellow sheet comes in 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 25, 30, 35, 40, 45, 50 mm and black sheet in 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 25, 30, 40, 45, 50 mm. Rod is natural color, Φ6, 8, 10, 12, 15, 16, 18, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 110, 120, 130, 140, 150 mm.
What flammability rating does Bakelite have?
The products are flame retardant and approved to UL94 HB and V-0.
Can Bakelite be used as an electrical insulator?
Yes. Its electrical insulation makes it suitable as an insulator, and it is used for laminated products such as electrical insulation boards and circuit boards.
Does Bakelite warp in storage?
Its good moisture resistance keeps warping in storage low, and it punches well at low temperatures.
