Reinforced Graphite Products

Reinforced graphite products are made of flexible graphite as basic material and different kinds of reinforcing materials. According to the different industrial requirements, the reinforcing material can be natural fibre, synthetic fibre, metal alloy filament, cotton fibre, glass fibre and carbonized fibre etc. To adapt different use condition, such metal filament can be added during twining as nickel alloy filament, stainless steel filament and copper filament etc. According to the production method and the field of usage, reinforced graphite materials can be produced in different forms, such as fabrics, sheets, boards, yarns, ropes etc…
Reinforced fibres, yarns can be woven into different expandable graphite packing using special process technique.
These products are suitable as asbestos replacements at high temperatures, excessive shaft speeds and in corrosive media and are the ideal non-asbestos solutions for shaft seals.
Because of their superior long-term stability, reinforced graphite products exceed the performance of organic fibrous materials.
Reinforced graphite is used world­wide in high-temperature and high-pressure braided packing applications, re­sulting in longer service lives, less leakage, less down-time and lower overall packing costs.
