About PTFE Coating
PTFE
PTFE XYLAN® coating provides a non-stick surface to which very few solid or liquid substances will permanently adhere.
Being non-protein binding and not supporting biological growth these are ideal for biology, microbiology and pharmaceutical applications as the PTFE coating provides bio-inert surfaces. The PTFE coating offers a unique combination of chemical inertness, purity, low permeability, heat resistance, toughness, and non-stick qualities.
Cleaning
They have excellent non-wetting properties that make cleaning very easy and can also undergo steam or chemical sterilisation.
High and Low Temperature properties
Excellent heat resistance and great cryogenic stability with a temperature range from -195°C to 260°C. Suitable for lifting or handling hot, cold or chemically active materials.
Corrosion Resistance
The chemical resistance of PTFE coating makes it normally impervious to chemical environments. The coating provides good resistance to acid and alkali solutions.
Examples of Chemical Resistance after 24 hours exposure
- HCI (concentrated) at room temperature, no change to coating.
- HCI (pH 2) at room temperature, no change to coating.
- HCI (pH 2) at 52°C, no change to coating.
- NaOH (50%) at room temperature, no change to coating.
- NaOH (pH 9.5) at 52°C, no change to coating.
- MEK (Methyl Ethyl Ketone – solvent) at room temperature, slight marks on coating.
- Toluene (solvent) at room temperature, slight marks on coating.
