What is Carbon Black?

 

Hello!

In this post, I will explain about the new material Carbon Black.

I have also posted articles explaining various topics such as Masterbatch and TiO2, so please refer to the link below.

What is Masterbatch? :

Carbon Black is a fine particle made of carbon, used as a reinforcing agent in tires and rubber products, and as a black pigment in plastics and inks. It is also used in various fields such as electronics and batteries to improve conductivity and durability.

Carbon Black

Carbon Black is made up of very fine particles and generally appears as a fine black powder. The particles themselves are on the nanometer scale, and individual particles are not easily visible to the naked eye. However, when many particles are gathered together, they appear as solid masses or powders, as shown in the picture above. This powder is a very dark black color, with a matte and non-glossy texture.

How Carbon Black is Made

1. Furnace Black: The most common type of Carbon Black, made by decomposing hydrocarbons at high temperatures using gas as a fuel. It has low production costs and can produce large quantities of products with various properties, making it widely used in tires and rubber products.

*Process: Combustion / Pyrolysis / Cooling and Collection.

2. Channel Black: Made by incomplete combustion of natural gas in a narrow channel. It has small particle size and a large surface area, making it excellent as a pigment. However, its production efficiency is low, and it is now almost not produced due to environmental reasons.

*Process: Incomplete combustion / Collection.

3. Acetylene Black: Produced by decomposing acetylene gas at high temperatures. It is used in electrical conductive materials, batteries, and conductive rubber due to its high conductivity and low impurity content.

4. Thermal Black: Manufactured by pyrolyzing natural gas at high temperatures. It has large particles and a low structure, making it primarily used as a filler rather than a reinforcing agent in rubber products.

5. Lamp Black: Made by incomplete combustion of vegetable oils or tar. This old manufacturing method is now only used for special purposes, such as art pigments.

Uses of Carbon Black

1. Reinforcing Grades: Primarily used in tires and rubber products, it enhances the strength and wear resistance of rubber. Grades include N220, N330, N660, among others.

2. Pigment Grades: Used as a pigment in paints, plastics, inks, etc., it increases coloring power and provides stable colors. It is used in applications where color uniformity and durability are important. Grades include N220, N550, N660, among others.

3. Conductive Grades: Used in conductive plastics or rubbers to provide electrical conductivity. It is applied in electronic devices, anti-static coatings, etc.

*In addition, Carbon Black is used in materials that may come into contact with food, such as pharmaceutical capsules or food packaging, and in printer toners and inks for high-resolution printing.

Products Made Using Carbon Black

1. Tires

-Car Tires: Carbon Black is used as a reinforcing agent in tires, significantly enhancing their durability and wear resistance. It plays a crucial role in extending the lifespan of tires, especially during high-speed driving.

2. Rubber Products

-Rubber Hoses: Carbon Black is added to rubber mixtures to enhance durability and flexibility.

Rubber Hose

-Rubber Bands: It is used in rubber band products where durability is important.

Rubber band

-Automotive Parts: Used in various automotive components such as rubber gaskets, seals, and bushings.

3. Plastic Products

-Plastic Masterbatch: As explained in previous posts, Carbon Black is mixed with various resin products like PP, PE, PET, etc., to create black masterbatches.

Plastics Masterbatch

-Plastic Pipes: Carbon Black acts as a UV stabilizer, enhancing the durability of plastic pipes.

Plastic Pipe

-Plastic Containers and Parts: It is used in plastic containers, cases, and other parts for UV protection and coloring.

4. Inks and Toners

-Printer Toner: Carbon Black is used in printer toners for high-resolution printing.

-Ink: Carbon Black is added to inks used for printing newspapers, magazines, packaging materials, etc., to provide sharp and uniform colors.

Inks

5. Paints and Coatings

-Industrial Paint: Carbon Black is added to paints used for automobiles, machinery, and building exteriors to provide a strong black color.

Black Paint

-Coatings: It is used in coatings to provide UV protection for building exteriors and wood finishes.

*Other Applications

-Cosmetics: Carbon Black is used as a black pigment in certain cosmetic products, particularly mascara and eyeliner.

-Pharmaceutical Capsules: It is used in pharmaceutical capsules for drug protection and color identification.

-Synthetic Fibers: Carbon Black is used to deepen and intensify the color of fibers and enhance their durability.
