Epoxy resin board can be used in many industries such as airplanes, automobiles, construction, electronic supplies, especially in the electronics industry, most products will use it. There are many types of epoxy resin boards, which can be divided into fr4, G11, G10, 3240 epoxy boards, etc. according to different models. These models have the same basic performance with different epoxy boards, and there are subtle differences in the fine joints. For example, G11 has particularly good high temperature resistance, and the halogen-free fr4 combustion will not produce toxic substances.

The features of epoxy resin board

1. The surface of the epoxy board is required to be smooth, free of bubbles, pits and wrinkles, but other defects that do not affect the use are allowed, such as: scratches, indentations, stains, and a small amount of spots. The edge of the epoxy board should be cut neatly, and there should be no delamination and cracks on the end surface.

2. Execution standard: GB / T1303.1-1998 (natural color), red, green and black are protocol standards.

3. Epoxy resin board temperature resistance level: Class B Epoxy board color: natural color (yellow), red, green, black, etc. (additional colors can be added, can be adjusted to a variety of colors)

4. Characteristics of epoxy resin board: The cured epoxy resin system has excellent mechanical properties. The strength of the 3240 epoxy board at medium temperature is high, and the electrical performance of the 3240 epoxy board at high humidity is stable.

5. Electrical properties of epoxy resin board: The cured epoxy resin system is an excellent insulating material with high dielectric properties, resistance to surface leakage, and arc resistance.

6. The applications of epoxy resin board : mechanical, electronic, electrical. 3240 epoxy board is suitable for mechanical, electrical, electronic, electrical and other fields. Epoxy board is also used for the processing of insulation parts and processed into various types of insulation parts. Equipment insulation structure parts.

7. Thickness of epoxy resin board: Normally it is 0.5 ～ 50mm, and thick board of 50 ~ 150mm can also be produced according to requirements.

The use of epoxy resin board:

1. Various forms:

The epoxy resin board is made of epoxy resin, and other resins can also be added, such as phenolic resin. Sex agent.

2. Easy curing:

The curing temperature of the epoxy resin is within 0 ~ 180, and it is not necessary to use an excessively high temperature during production, which is convenient for control.

3. Strong adhesion of epoxy resin board

Because of the molecular relationship, epoxy resin itself has a very high adhesion, can be used as an adhesive. In the epoxy board, resin and glass fiber are firmly bonded together, and it is difficult to be separated by external force.

4. Low shrinkage of epoxy resin board

Epoxy resin board has stable thermal performance and low shrinkage. Even in a humid and hot environment, it can maintain its original appearance.

5. Remarkable mechanical ability of epoxy resin board

The epoxy board has high strength, light weight, can withstand strong external force impact, and has small electrical breakdown ability. It can work for a long time at high-strength voltage and current and resist fatigue.
