Teflon Graphite Pipe

Teflon graphite tube is a special functional material with high-purity graphite as the base material and a polytetrafluoroethylene composite layer coated on the surface through a special process. The graphite tube is a chemical combination of graphite and PTFE coating through a high-temperature sintering process. It combines the excellent thermal conductivity of graphite and the chemical inertness of PTFE coating, and is a key component under extreme working conditions.

Teflon graphite tube is superior to ordinary graphite tube in the following aspects: 1. Its corrosion resistance: Compared with ordinary graphite tubes, the surface of Teflon graphite tubes can withstand the erosion of concentrated sulfuric acid, hydrofluoric acid and strong alkali media, and can also resist intergranular corrosion; 2. Its non-wetting characteristics: The surface characteristics of Teflon graphite tubes can achieve super-hydrophobic and anti-adhesion functions; 3. Its tribological properties: Teflon graphite tubes have a low dynamic friction coefficient, which makes them both self-lubricating and wear-resistant.

Teflon graphite tubes can be used as corrosive medium delivery pipelines and reactor linings in the chemical industry; high-purity electronic special gas delivery systems in the semiconductor industry; high-temperature vacuum furnace thermal field components, etc. Relying on its material composite design principle, it successfully solves the pain points of traditional graphite tubes such as high porosity and easy permeability, and insufficient corrosion resistance of metal tubes.
