Introduzione Diflon D

The elongation at break value measured lengthwise at 23°C is 50%; this value is not influenced by a prolonged exposure to high or low temperatures and to corrosive substances. Diflon D is a self-lubricating material; its resistance to wearing is 20,000 times higher than PTFE, with higher surface hardness and lower deformation under constant loads; its elasticity is optimal and is also retained at very high and very low temperatures. This ensures excellent plastic memory to Diflon D (50% cold, 80% when heated). When sliding on a metal surface Diflon D leaves a thin layer on the metal; as a result Diflon D slides on a thin layer of Diflon D, which increases the material’s self-lubricating properties, low friction and When using Diflon D as an anti-friction material it is possible to avoid any kind of seizing and lubrication problems. The surface roughness recommended for contact friction surfaces is Ra 0.2-0.8 mm. Materials: all carbon steels and hardened surfaces, minimum hardness HRC 35.


  1. Contact with acids, solvents, in dusty or polluted environments.
  2. Positions inaccessible for lubrication and maintenance.
  3. High and low temperatures (from -240°C to +280°C).
  4. When in dry operation, the stick-slip phenomenon must be.
  5. Very low wear factor.
  6. Flexibility and impact strength.
  7. Total elimination of the lubricant to avoid any contamination of the compressed gas.
  8. Chemically inert to almost all compressed gases.
  9. Easy machining on machine tools.
  10. Differently from many elastomers, Diflon D does not age even after prolonged exposure to chemical agents or at high and low temperatures.
