Differences between an electrical board and an epoxy board

What are the differences between an electrical board and an epoxy board? In response to this question, we discussed with you about this topic. As far as I know, the role of bakelite is mainly insulation, and the epoxy board is made of glass fiber cloth bonded with epoxy resin and heated and pressurized. For 3240, the mechanical properties are high at medium temperatures, and the electrical properties are stable under high humidity. Let’s learn more about this.

Electrical board:

Alias ​​plastic board, full name epoxy phenolic laminated cardboard. The color is orange and black. The specification size is 3-50mm*1000mm*1220/2000mm (thickness*width*length). The bakelite board uses high-quality bleached wood paper and lint paper as reinforcing materials, and is made of a phenolic resin made from high purity, fully synthetic petrochemical raw materials as a resin binder.

Features: good electrical performance at room temperature, good machining performance, specific gravity 1.45, warpage ≤ 3 ‰, with excellent electrical, mechanical and processing properties. Paper-based bakelite is the most common laminate, and it is also the most widely used industrial laminate in the world.

Application: Used for motor, electrical equipment and insulating structural parts with high mechanical performance requirements. Good mechanical strength, mainly used in ICT, ITE fixtures in the processing of insulating parts, test fixtures, silicone rubber key molds, fixture plates, mold splints, table polishing pads, packaging machines, combs and so on.

Epoxy board:

Also known as 3240 epoxy phenolic glass cloth laminates, the color is yellow, black, the product is made of special alkali-free glass fiber cloth for electrical epoxy phenolic resin, after baking hot pressure. The product has high mechanical and dielectric properties, good heat resistance and moisture resistance, and good mechanical processing, and the heat-resistant grade is B grade. It is suitable for insulating structural parts in motors and electrical equipments. Use in humid environments and transformer oils.

Board size: 1020*2020 mm, 1220*2020mm, 1220*2470mm, 1220*1220mm, 1020*1020 mm

Difference between epoxy board and electrical board:

Epoxy board is a glass fiber reinforced epoxy board,
Bakelite is a phenolic plastic board,
The strength of epoxy board is much higher than that of bakelite.
Bakelite’s toughness is not high, its elasticity is poor, it is brittle, and it cannot be used as a bow arm.
1. The price is not much different. The epoxy board is between 23 and 43 yuan/Kg, while the electrical board is around 19 to 57 yuan/kg.
2. The shrinkage rate is related to the composition and processing method of the resin.
3. In addition to the advantage of price and raw materials, there is no advantage for the electric board, and the epoxy board is easy to use.

insulating board

Epoxy resin board is a high-pressure epoxy resin and glass fiber cloth synthesis, electrical board is a phenolic plus some powder with cotton cloth, so the epoxy board is not good performance of wood, electrical board than epoxy board physical processing With high performance, no matter if it is epoxy board or Bakelite board, if you have such needs, you can get in touch with the company through the Internet or telephone.
