Araflon 6426
Features
Araflon 6426 is a packing made from high quality, smooth, synthetic and partly pre-impregnated continuous aramid fibers (Kevlar) with multiple applications of PTFE impregnating agent and lubricant additive. The aramid fibers are diagonally braided. This is a high quality and high strength packing. It is used, in particular, in the chemical, petrochemical, waste water and paper industries.
Advantages
- High resistance to abrasive media
- Long service life
- High purity
- Extremely stable and durable

Notes
Because the aramid fibers are highly stable, we recommend a surface hardness of 40 … 60 HRc to avoid wear on the running surfaces of shafts and sleeves.
