The story and application of bakelite sheet

Bakelite sheet is also called glue board, phenolic laminated board. It is made of high-quality bleached wood paper and cotton lint paper as raw materials, and made of phenolic resin made of high-purity, fully synthetic petrochemical raw materials as resin binder.

The story of bakelite

It was discovered by Belgian scientist Leo Baekeland  in an accidental experimental accident. At the beginning of the twentieth century, a cat in Baekeland accidentally knocked over the reagent. After the reagent mixture reacted, it overturned on a piece of cheese. The mixture formed a hard block as smooth as ivory. Baekeland picked up a piece and studied it. That piece of weight is suitable, like wood, it feels hard to the touch, and it makes a ding-dong sound when knocked. It is not easy to break a piece as thick as a coin, indicating that it has a certain mechanical strength, which is also similar to wood. near.

Bakelite came into this world to bully wood. Bakelite's insulation, fire resistance, and moisture resistance are all triumphs compared to wood. He basically has the properties that wood has, but he doesn't have properties that wood doesn't have. In addition, it is moisture-proof, fire-proof and oil-resistant, and wood that has these points at the same time does not have it.

The advantages of bakelite sheet

Bakelite products are the first choice for many plastic products because of their low price of raw materials and excellent product characteristics (the product has good mechanical strength, anti-static, and intermediate electrical insulation). The raw material price of bakelite products is nearly 50% of the price of ABS. Although bakelite products need to be heated and formed, the processing time is longer than that of ordinary plastics, and the mold wear is larger, but because of the dominant position of raw material prices, it is still the preferred substitute for many plastic parts.

Because bakelite has good electrical properties at room temperature, good machinability, and warpage ≤3‰, it has excellent electrical, mechanical and processing properties. Paper bakelite is the most common laminate and the most versatile and used industrial laminate in the world.

Application of bakelite board

1. This product is suitable for insulating structural parts in motors and electrical equipment with high mechanical performance requirements, and can be used in transformer oil. Good mechanical strength, suitable for drilling pads, distribution boxes, fixture boards, mold splints, high and low voltage wiring boxes, etc. in the PCB industry.

2. Good mechanical strength, mainly used in the processing of insulating parts in ICT and ITE fixtures, test fixtures, silicone rubber key molds, fixture plates, mold splints, table grinding pads, packaging machines, tea tray combs, etc.

How long can bakelite sheet be used

The service life of bakelite sheet is generally 3 to 5 years.

Bakelite is a common name for phenolic plastics. It is relatively brittle, has high hardness, and is easily broken in large pieces. Therefore, bakelite boards will deform significantly after a long time of use, and heat insulation boards with poor temperature resistance will be carbonized or delaminated for a long time.

Is bakelite board toxic

Bakelite itself is not poisonous, and is actually a non-toxic product. Bakelite is a thermosetting plastic and a phenolic plastic. When heated, it will decompose formaldehyde, which is a toxic substance.

Can bakelite board be recycled

Bakelite is, thermosetting plastic is phenolic plastic, once it is formed, it is difficult to change its shape, and it is difficult to decompose in the natural environment, so the recycling value is not large.
