Product details

Bakelite board, also known as plywood and phenolic laminated paperboard, is manufactured by using high-quality bleached wood and absorbent cotton paper as reinforcement and high purity, fully synthetic petrochemical raw materials reacted with phenolic resins as the resin binder.

Bakelite is an excellent insulating material with phenolic resin as the main component. With regard to its heat resistance, a common phenolic laminated paperboard, for example, is generally classified as Class E, with a maximum temperature of 120°C. However, when high-grade materials are used, it is not possible to use these materials for insulating purposes. However, when manufactured with high-grade materials, the temperature resistance of bakelite boards can be significantly increased, even up to about 350°C. This feature allows them to be used in high-temperature environments. This characteristic allows it to remain stable in high-temperature environments, providing reliable insulation protection for all types of electrical equipment.

Characteristics of bakelite board:

Good electrical properties at room temperature, good mechanical properties, specific gravity 1.45, warpage ≤ 3 ‰, with excellent electrical, mechanical and processing properties. Paper Bakelite is the most common laminate and the most widely used and utilized industrial laminate in the world.

Main characteristics:Good mechanical strength, anti-static, intermediate electrical insulation, is made of insulating impregnated paper impregnated with phenolic resin, baked, hot pressed and become. The product is suitable for use as insulating structural parts in electric motors and electrical equipments which require high mechanical properties, and can be used in transformer oil. With good mechanical strength, it is suitable for pads for drilling in PCB industry, distribution boxes, jig boards, mold cleats, high and low voltage wiring boxes, packaging machines, combs and so on. Suitable for motor, machinery mold, PCB, ICT jig. Molding machine, drilling machine, table grinding pad.

What are the characteristics of bakelite

1. With insulation and high temperature resistance and other advantages, it can be said that it is suitable for use in electronic products, switches, resistors, molds and so on.

2. It is actually a synthetic chemical substance. After it is heated and molded, it will be cured, can not be molded into something else, because it does not absorb water, but also has a high temperature resistance, high strength, so that this product is also widely used in electrical products.

3. Good room temperature electrical properties, specific gravity is about 1, 45, warping ≤ 3 ‰, with good electrical and processing properties. Can be said to be more common is the paper glue wood, is also used more widely a, the most used industrial laminates. Suitable for use in high mechanical performance requirements of the motor and electrical equipment.

4. Good mechanical strength, mainly it will be used in ICT and ITE jigs, molds, mold cleats, packaging machines, combs and other processing.

5. Good molding, its shrinkage rate and direction is also greater than the amino plastics, and it contains moisture volatiles. It needs to be preheated before molding, molding in the exhaust, if not, but also to increase the mold temperature and molding pressure, the liquidity of the impact is also relatively large, more than 160 degrees, the liquidity will fall.

Economic benefits of Bakelite

Bakelite is the preferred substitute for many plastic products due to its low raw material price and its excellent product characteristics.

The raw material price of Bakelite products is almost 50% of the price of ABS. Although bakelite products molding due to heating molding, processing time is longer than ordinary plastic, mold wear and tear on the higher steel requirements, but because of its advantageous raw material prices, is still a lot of plastic parts of the first choice for substitutes.

Analysis of the difference between epoxy board and bakelite board

Epoxy board and bakelite board comparison

1.Compositional analysis:

Epoxy board, this composite material to epoxy resin as the main body, often combined with fiberglass cloth or paper and other reinforcing materials. The characteristics of epoxy resin gives it excellent mechanical strength, chemical resistance and electrical insulation, so in the manufacture of high-performance electrical and electronic products, such as PCB, when favored.

Bakelite, on the other hand, is created by combining phenolic resin with insulating fibers such as paper or cotton fibers. The base material is mainly paper, which is impregnated and pressed with phenolic resin to form a composite material with excellent electrical insulation, abrasion resistance, and heat resistance. Bakelite boards are often used to make insulating parts for electrical equipment, such as insulating mats and electrical partitions.

2. Application areas:

Epoxy boards have a wide range of applications, covering electronic, electrical and mechanical fields, especially in PCB manufacturing plays an indispensable role. Bakelite boards are mainly used in the manufacture of electrical equipment and motor insulation, such as motor groove sets, bulkheads and switchgear.

3. Temperature rating:

The temperature rating of epoxy boards varies depending on the product and formulation, but some high-performance products can reach quite high levels. In contrast, bakelite boards usually have different temperature grades, such as B, F, H, etc., to indicate its heat-resistant properties, especially H-class bakelite boards, in a high-temperature environment can maintain excellent stability.

In summary, epoxy board and bakelite board in the electrical insulation properties and their respective areas of application are outstanding, the specific choice of which material, according to the actual needs of the project and standards to determine.

Both epoxy and bakelite boards exhibit excellent electrical insulation properties in their respective fields. However, the choice of material should be based on the actual needs and criteria of the project to ensure the best application results.

Bakelite boards - multifunctional insulating material

Applications in the mechanical field

Bakelite has a wide range of applications in the mechanical field due to its excellent mechanical strength. It is often used as a pad for drilling holes in the PCB industry, and also plays an important role in distribution boxes, jig boards, mold clamps, and high and low voltage wiring boxes. In addition, bakelite boards are used in the manufacturing of packaging machines, combs, motors, mechanical molds, PCBs and ICT jigs. Its excellent properties even allow it to be used in transformer oil, further broadening its range of applications.

Applications in Electrical Appliances

Bakelite, as a man-made synthetic chemical, has excellent physical and electrical properties. When it is heated and molded, it solidifies into a stable form that cannot be reshaped into other items. The material's non-absorbent and non-conductive properties, as well as its resistance to high temperatures and strength, make it widely used in the manufacture of electrical products. Bakelite is one of the indispensable materials, whether for circuit boards, electrical enclosures, or other electrical components

Bakelite board application field:Suitable for PCB drilling, silicone rubber mold. Fixture, switchboard, electrical machinery parts.
