What are the advantages of expandable graphite?

1. Expandable graphite can improve the processing temperature of flame retardant materials.
In industrial production, the commonly used method is to add flame retardants into engineering plastics, but due to the low decomposition temperature, decomposition will occur first, resulting in failure. The physical properties of expandable graphite are stable, which will not affect the quality of processed materials and improve the flame retardant property.

2. The smoke produced by expandable graphite is less and the effect is significant.

Generally speaking, halogenated flame retardants will be added to make the object flame retardant and flame retardant function, but will produce smoke and acid gas, affect human health, corrosion of indoor equipment; Metal hydroxide will also be added, but it has a great impact on the impact resistance and mechanical strength of the plastic or matrix, and can also affect people’s health and corrode indoor equipment. When the air is not very smooth, adding phosphorous flame retardants can have serious effects on people. Expandable graphite is ideal. It produces a small amount of smoke and has a significant flame retardant effect.

3. Expandable graphite has good heat insulation and corrosion resistance.

Expandable graphite is a corrosion-resistant material that exists as a stable crystal. It does not deteriorate during decomposition and oxidation until it fails due to the limitations of shelf life and stability.

In summary, the advantages of expandable graphite make it the material of choice for heat insulation and flame retardant. When choosing expanded graphite, we must choose high quality expanded graphite products to achieve industrial effect, not just for low price.
