Fine Carbon Materials

CSCC's isotropic graphite uses self-produced Meso-phase carbon powder(MCMB) as a raw material. Due to the self-sintering characteristics of MCMB, isotropic graphite can be produced without impregnation process, which saves time and is environment friendly. Compared with commercial products, our products have the properties of high density, high mechanical strength and high purity.

Applications

Crucible, Support for Semiconductor Applications

CSCC's products can meet the requirements of high-purity, high thermal conductivity, and thermal shock-resistant crucibles or process components required by the semiconductor industry.

Mechanical Parts

GBM1 has the characteristics of high mechanical strength, high density and wear resistance, and can be used for mechanical bearings, seal rings and other purposes.

Continuous casting

GBE1 and GBCR1 have high thermal conductivity and corrosion resistance, and can be used in high temperature environments, which can meet the requirements of continuous metal casting.

Molds

Glass molds require high-density, low-roughness, and high-strength graphite materials to produce three-dimensional glass that meets the use of 3C products.

Gas permeable parts

The unique self-sintering process makes the product have porosity, which cannot be achieved by normal impregnated graphite. This property can be applied to processes that require air permeability.

Related raw materials

BCP

There are α-resin in middle of BCP sphere, which has higher molecular weight. α-resin does not soften or melt during the heating process but only pyrolysis. On the other hand, the β-resin at outer rings melts during the heating process. As a binder, β-resin stick each particle, and sinter to solid when heating up.

Advantages:

Self-Sintering, High purity, Short Production Period

Refined Impregnation Pitch

CSCC produce high quality Refined Impregnation Pitch with good penetration. For UHP & HP graphite electrode impregnation, the use of RPB can increase the weight gain and yield, and significantly improved flexural strength and reinforcing.
