Introduction to the performance and use of bakelite
2021-09-08

Bakelite is not wood. It is not found in the natural world like fir and pine. It is a chemical product made from three raw materials: phenol, formaldehyde, and ammonia. Phenol is a crystal in the state of a colorless needle tip. It will turn red when exposed to light, and it will also change color when met with alkali. Formaldehyde is commonly known as formalin, which has strong anticorrosive function and high corrosiveness. Ammonia reacts with acid and is explosive. It is often used as a raw material for fertilizers. Bakelite is superior in performance and widely used.

The surface of bakelite material is smooth and flat, the color samples are black, reddish brown, brown, etc., the thickness is uniform, without pits, scratches, black spots, and no whitening. The touch is thick, not rough, hard and strong, resistant to high temperature, low temperature and friction. The operating temperature range is -40 ℃ ~ 140 , in this temperature environment, the performance will not change much. When struck, the sound is not heavy, like a wooden board. Its disadvantage is that the texture is relatively brittle, and it cannot withstand the impact and pressure of too much external force.

Bakelite products are more common in life, and can make telephones, vinyl records, auto parts, etc., and there was a craze for some time in the past. The current bakelite products are mainly used in the industrial and electronic fields, and can be made into various mechanical parts to play a role in protection, insulation and support.
