What are the Differences Between Epoxy Board and Electric Bakelite Board?
- By : Insulation Materials
What are the differences between epoxy board and electric bakelite board? These two materials are all the electrical insulation materials. Epoxy board, also known as epoxy glass fiber board, epoxy phenolic laminated glass cloth board, is a high polymer that can be used in the medium temperature environment.
According to the heat resistance degree, the epoxy board will be divided into y, a, e, B, F, h, C and other grades.
Electric bakelite board is phenolic board. The strength of epoxy resin board is much higher than that of bakelite. The bakelite has low resistance, poor elasticity and brittleness, so it can not be used as bow arm.
1. The price difference between epoxy board and electric bakelite board is not big. The epoxy board is 28-30 yuan / m2, and the electrical board is 24-26 yuan / m2.
2. The shortening rate of epoxy board and electric bakelite board is related to resin composition and processing method.
3. In addition to the price and material advantages of epoxy board and electric bakelite board, electric board has no advantages. Epoxy boards are still easy to use.
The epoxy resin is composed of epoxy resin and high pressure fiberglass cloth. The circuit board is pressed with phenolic resin and some powder and cotton cloth. Therefore, the function of electrical bakelite board is better than that of physical treatment of epoxy board.
