Description
PTFE sheet is a versatile material known for its low friction and high chemical resistance. Ideal for various high-temperature applications.
Material Properties
PTFE, or Polyetrafluorethylene, is a thermally stable plastic with a melting point of 327°C and Shore D hardness. It exhibits excellent dielectric properties, making it suitable for high-frequency applications.
Advantages and Disadvantages
PTFE sheets have the third-lowest coefficient of friction of any solid material, making them ideal for low-friction applications. However, they are soft and can be prone to damage when clamped. They also decompose at temperatures above 350°C, releasing toxic fumes.
Performance Characteristics
PTFE sheets are resistant to high and low temperatures, chemical reactions, and corrosion. They are preferred for applications requiring low friction, such as bearings and slide plates, and are used in laboratory environments for corrosive materials.
Machining and Bonding
Due to their softness, PTFE sheets can be difficult to machine without damage. They require surface preparation for bonding, often involving etching, to ensure adhesives adhere properly.
Applications
PTFE sheets are used in a variety of applications, including as components in sliding mechanisms, for electrical insulation, and in laboratory settings. They are also utilized in cookware as Teflon® lining.
