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