Overview
PTFE chemical formula
Generalities of the PTFE
Dollfus & Muller is manufacturing PTFE coated belts for printing dryers and relax dryers and PTFE sheets which are used as compactor introductory sheets.
PTFE (etymology: tetra-fluoroethylen + on ending for plastic materials) is the registered trademark since 1945 for polytetrafluoroethylen (PTFE) in common language from the American company DuPont de Nemours. This Polymer is thermostable, has a huge chemical inertia and an anti sticking power.
Physical characteristics of the PTFE
- Density: 2.2
- Friction Coefficient: 0.05 to 0.1 (3rd most down friction coefficient, after the BAM and the diamond carbon
- The only surface on which a gecko cannot climb (thanks to its resistance to Van de Waals forces)
Thermical Characteristics of the PTFE
• Properties deterioration : 260 °C
• Decomposition point : 350 °C
• In high temperature emit a harmful gas
Mechanical characteristics of the PTFE
• Young Module : 0.5 GPa
• Maximum constraint : 23 MPa
Chemical Characteristics of the PTFE
• Chemically inert
• High resistance to the corrosion
