Understanding the Different Types of PTFE Sheet Gaskets:

PTFE sheet gaskets are available in various types, each designed to suit specific application requirements:

 Virgin PTFE Sheet Gaskets

Virgin PTFE sheet gaskets are made from pure PTFE material without any fillers. They offer excellent chemical resistance, low friction, and wide temperature capabilities. These gaskets are commonly used in applications where purity and resistance to aggressive chemicals are critical.

 Filled PTFE Sheet Gaskets

Filled PTFE sheet gaskets are reinforced with fillers to enhance specific properties. Fillers such as glass fibers, carbon, graphite, or other materials can improve the gasket's strength, dimensional stability, or thermal conductivity. Filled PTFE gaskets are suitable for applications requiring higher pressure ratings or improved creep resistance.

Expanded PTFE Sheet Gaskets

Expanded PTFE (ePTFE) sheet gaskets are manufactured by expanding virgin PTFE. This process creates a unique microstructure with excellent sealing properties, even at low loads and moderate bolt stresses. ePTFE gaskets exhibit superior conformability, making them ideal for uneven or damaged flange surfaces.
