PTFE-based composite
PTFE-Based Composite – Polytetrafluoroethylene (PTFE)-Based Coating
Polytetrafluoroethylene (PTFE) is a fluoropolymer derived from tetrafluoroethylene, renowned for its exceptional properties. It offers outstanding resistance to most chemicals, has an extremely low coefficient of friction, and remains stable at elevated temperatures. These characteristics make it ideal for applications where chemical resistance and dry lubrication are essential.
Benefits
– Friction reduction: Thanks to its low coefficient of friction, it minimizes wear and improves the performance of moving parts.
– Exceptional non-stick properties: Ideal for preventing material adhesion and facilitating demolding processes.
– Suitable for food applications: Food-grade according to the PTFE composition, compliant with health standards.
Features
– Chemical resistance: Excellent stability against most chemicals, making it suitable for aggressive environments.
– Very good coefficient of friction: Exceptional properties for effective lubrication, reducing friction without the need for an external lubricant.
– Dry lubrication: Ideal for applications where lubrication is limited or difficult to maintain.
– Thickness: From 25 to 35 µm, providing long-lasting protection without affecting part geometry.
– Hardness: Between 50 and 65 Shore, depending on the PTFE composition, ensuring good wear resistance while Remains sufficiently flexible.
– Temperature resistance: From 260 to 300°C, depending on the PTFE composition, allowing its use in high-temperature environments.
Typical application
– Food industry: Molds, sealing jaws, cutting blades for food products.
– Industrial sector: Casings, arch supports, bushels, guides, hoppers, trays, frames.
– Automation and mechanics: Drums, augers, components in contact with sticky or abrasive products.
PTFE coating offers significant benefits in terms of reduced wear, improved part performance, and compliance with food safety standards, particularly for applications in demanding conditions.
