Description
PTFE sheet is a versatile material known for its low friction and high-temperature resistance. Ideal for various industrial applications.
Material Properties
PTFE, or Polyetrafluorethylene, is a thermally stable plastic with a melting point of 327°C and a Shore D hardness. It exhibits excellent dielectric properties, making it suitable for high-frequency applications.
Performance Characteristics
PTFE sheets are resistant to extreme temperatures, chemical reactions, and corrosion. They maintain their properties even under stress and are preferred for applications requiring low friction.
Applications of PTFE Sheet
These sheets are commonly used in sliding applications such as plain bearings and slide plates. They are also utilized in laboratory settings for storing corrosive materials and in optical radiometry for measuring light.
Machining and Bonding
PTFE can be challenging to machine due to its softness and low friction. Surface preparation is essential for bonding, typically requiring etching with specific solutions.
Safety Considerations
When heated above 400°C, PTFE can emit toxic fumes. Proper handling and machining precautions are necessary to avoid health hazards.
