Tokarec

CC Composite

Tokarec is a CC composite material with a strong carbon fibre and carbon matrix. This composite has excellent mechanical properties and is suitable for a wide range of high-temperature applications.

Tokai Carbon has developed a new material based on Tokarec that is flexible, TokarecFlex

Features:

  • High Specific Strength and High Specific Modulus
  • Excellent Heat and Thermal Shock Resistance
  • Low Coefficient of Thermal Expansion
  • Low Thermal Conductivity
  • High Purity
  • High Strength to Weight Ratio

Applications:

  • Components for Single and Multi Crystal Pullers
  • Structural Parts for Heat Treatment Furnaces
  • Heaters
  • Jigs and Fixtures
  • Carriers for Silicon Solar Wafers
