Why is phenolic resin used as a raw material for carbon molecular sieves?

There are many raw materials for producing carbon molecular sieves, including biomass carbon and coal-based carbon. Currently, the main raw material is phenolic resin carbonized material. This material is used by reputable carbon molecular sieve manufacturers in China. Phenolic resin has the following characteristics:

(1) High stability: Phenolic resin materials exhibit high stability at high temperatures. Even under high-temperature conditions, its structure maintains integrity and dimensional stability. This characteristic makes phenolic resin carbon materials widely used in high-temperature industries, such as refractory materials, friction materials, and binders.

(2) High residual carbon rate: Under high-temperature conditions, phenolic resin materials produce a high residual carbon rate, which helps maintain its structural stability. This characteristic makes phenolic resin carbon materials important in the field of high-temperature refractory materials.

(3) Chemical resistance: Phenolic resin carbon materials have good chemical resistance and can resist the erosion of various chemical substances. This characteristic makes them widely used in the chemical and (based on actual reports) industries. In addition, phenolic resin has low smoke and low toxicity, as well as strong adhesion and flame retardancy, which also provides protection for the manufacture of high-quality carbon molecular sieves.
