Insulation board includes a wide range of types, among which epoxy board is one of them.

How to better distinguish the various grades of boards in the epoxy board family? Domestic epoxy boards are usually divided into: 3240 epoxy board, fr4 epoxy board, and the materials and production processes used are also different. The following is the knowledge of epoxy board for you.

1. 3240 epoxy board is commonly known as: 3240 epoxy phenolic glass cloth laminate. It is made of electrical glass cloth impregnated with epoxy resin, dried and hot pressed. Epoxy resin refers to an organic polymer compound containing two or more epoxy groups in the molecule. Except for a few, their relative molecular mass is not high. The molecular structure of epoxy resin is characterized by the presence of active epoxy groups in the molecular chain. The epoxy groups can be located at the end, middle or ring structure of the molecular chain. The cured epoxy resin system is an excellent insulating material with high dielectric properties, surface leakage resistance and arc resistance. 3240 epoxy board is widely used in machinery, electronics and electrical applications. It is suitable for mechanical, electrical, electronic, and electrical appliances. It is also used for the processing of insulating parts and processed into various insulating accessories. Equipment insulation structural parts.

2. The main material of fr4 epoxy board is imported semi-cured sheet, with colors of white, yellow, and green. It still has high mechanical strength at room temperature of 150°C, good electrical properties in dry and wet states, and flame retardant. It is used for insulating structural parts in electrical and electronic industries. It is carefully manufactured using imported raw materials, domestic presses, and standard processes; the main specifications are 1000*2000 mm 1020mm*1220mm. Because of the advantages of raw materials, it guarantees high quality, low price, and timely delivery. It has a solid customer base at home and abroad and enjoys a high reputation. fr4 epoxy board has stable electrical insulation performance, good flatness, smooth surface, no pits, standard thickness tolerance, and is suitable for products with high-performance electronic insulation requirements, such as FPC reinforcement board, PCB drilling pad, glass fiber meson, potentiometer carbon film printed glass fiber board, precision planetary gear (chip grinding), precision test board, electrical (electrical) equipment insulation support partition, insulation pad, transformer insulation board, motor insulation, grinding gear, electronic switch insulation board, etc.

3. 3240 epoxy board and fr4 epoxy board are widely used in various industries. Customers can better choose the board suitable for themselves without any requirements, and have better choices in terms of product quality and product cost.
Insulation board

The above three types are all glass fiber boards.

Usually the epoxy board on the market is phenolic epoxy, the yellow one, which is generally not used as a rigid circuit board substrate, but for electrical insulation purposes.

FR4 is a pure epoxy board of NEMA standard. The normal color should be dark green, which is the color of epoxy. There are also yellow ones. Generally speaking, yellow FR4 is called yellow material, and white (green) is called white material.

FR4 is more expensive than epoxy board, and the price of fiberglass board cannot be confirmed.

Epoxy fiberglass board is widely used in many industries, including electronic PCB, hardware processing, and electrical equipment applications.
