1. Different uses. The main raw materials for the production of circuit boards are alkali-free glass cloth, fiber paper, and epoxy resin. Fiberglass board: base material fiberglass cloth, epoxy board: adhesive is epoxy resin, FR4: base material cotton fiber paper. All three are fiberglass boards.

2. Different colors. Usually the epoxy board on the market is phenolic epoxy, yellow. Not used as a substrate for hard circuit boards, for electrical insulation. FR4 is NEMA standard pure epoxy sheet. The normal color is 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 glass fiber board cannot be confirmed.

3. The nature is different. Fiberglass board has the characteristics of sound absorption, sound insulation, heat insulation, environmental protection, flame retardant and so on. FR-4 is also known as glass fiber board; glass fiber board; FR4 reinforcement board; FR-4 epoxy resin board; flame retardant insulation board; epoxy board, FR4 light board. Epoxy glass cloth board; drilling board for circuit board.

·

Epoxy fiberglass board is also referred to as epoxy board or fiberglass board and insulation board in the market. Its colors are usually water green (white), yellow, black, and other colors can also be requested by customers. Customized production. Its biggest features are strong processing performance, high hardness, high strength, low water absorption, and has the comprehensive advantages of other materials, so the application fields are very wide that include electronics industry, machinery industry, packaging industry, medical industry Specific application: glass wheel for polishing, spacer in the constant temperature heating sheet of battery pack, various jigs, mechanical parts, reinforcement board for flexible circuit board, insulating gasket, etc.

It is specifically applied to: the star wheel during glass polishing, the spacer in the constant temperature heating sheet of the battery pack, various jigs, mechanical accessories, the reinforcement board of the flexible circuit board, the insulating gasket, etc.

Insulation parts are suitable for high and low voltage transformer parts, avionics electrical insulation parts, water conservancy and hydroelectric insulation parts, switch cabinet insulation parts, inverter insulation parts, industrial electric furnace insulation parts, semiconductor insulation parts, electrified railway insulation parts, shipbuilding insulation parts, nuclear power Insulation components, busbar insulation spacer gasket. Has high mechanical and dielectric properties, better heat resistance and moisture resistance. The company's products are mainly sold in domestic and foreign markets, and the domestic market is mainly sold to the Pearl River Delta region; foreign markets are southeast asian countries.

1. Motor insulation

Such as: high and low voltage transformer accessories, water conservancy and hydroelectric insulation parts, switch cabinet insulation parts, inverter insulation parts, industrial electric furnace insulation parts, semiconductor insulation parts. This product is made of high-quality FR-4 insulation material. Material: glass fiber cloth, epoxy resin, continuous temperature resistance of 155 degrees, short-term temperature resistance can be as high as more than 240 degrees, with high mechanical properties and medium Electrical properties, better heat resistance and moisture resistance and good machinability. The electrical insulation performance is stable, the flatness is good, the surface is smooth, without pits, and the thickness tolerance standard.

2. High-speed rail insulation

Such as: avionics electrical insulation parts, electrified railway insulation parts, shipbuilding insulation parts, nuclear power insulation parts, etc. The material of this product is taken from the SMC epoxy ethylene (that is, SMC plus glass fiber) which is made by hot pressing of the mold. Its performance is better than that of the general SMC. Its water absorption is only 0.23%, and its bending strength and compressive strength can reach 175MPa , 13 times of tensile strength 75MPa, volume resistivity reaching 4.9 * 10 (this parameter is generally not achieved by insulating materials), electrical strength 23KV / mm, flammability is the best V-0 level among insulating materials Because of its excellent characteristics, this kind of molded parts are usually used in large quantities on high-speed rail, motor cars, and subways.

3. Insulation of battery cover

Such as: electric bicycle batteries, electric locomotive motors, large electric vehicle power lithium battery modules, home energy storage products, electric vehicle power batteries, etc. The battery cover plate acts on the surface of the battery to fix it, and directly contacts the strong acid solution of the battery and the electrode rod. It has high requirements on acid and alkali corrosion resistance and voltage impact of the board.
