Core Product

Composite Graphite-Reinforced Plate utilizes high-purity flexible graphite as the base material and combines reinforced frameworks with composite fibers (glass fiber, carbon fiber) or metal reinforcements (stainless steel, titanium alloy).

Through high-temperature pressing and precision molding processes, it integrates graphite's corrosion resistance and heat resistance with the high-strength characteristics of reinforcement materials. This advanced composite material serves as a high-performance structural solution for industrial equipment, providing sealing, load-bearing, and protective functions.

Product features

Strong and resilient structure: The graphite substrate provides excellent sealing and chemical inertness, and the reinforced skeleton is evenly dispersed through gradient distribution technology, which improves the impact strength of the plate by more than 40% and solves the problem of brittleness of pure graphite.
Wide range environmental adaptation: long-term temperature tolerance-200~300℃, short-term tolerance to 350℃ high temperature, stable performance in acid and alkali, organic solvent and humid environment, no swelling, no cracking phenomenon.
Precision performance control: The proportion of reinforcing materials (5%-20%) can be adjusted to achieve customized performance, which can accommodate the requirements of high flexibility (bending radius ≥50mm) or high rigidity (elastic modulus ≥8GPa).
Long-term durability: the surface is solidified to form a dense protective layer, the friction coefficient is as low as 0.12, the wear rate is less than 0.001g/ (cm²·h), and the service life is 2-3 times longer than that of ordinary graphite plate.
