Fluorosint™ 500 PTFE Sheet - Mica Filled

Fluorosint™ 500 PTFE - Mica Filled 

Fluorosint™ 500 is a mica filled PTFE sheet material. It offers a unique combination of stability and durability, ideal for sealing applications demanding precise dimensional control. Being mica filled, it offers a nine times greater resistance to deformation under load than regular unfilled PTFE and greater wear resistance.

Fluorosint™ 500 also has exceptional chemical and hydrolysis resistance and excellent mechanical and tribological properties. Its coefficient of linear thermal expansion mirrors that of aluminium, being only 1/4 that of virgin PTFE. This makes this product a common option for designers with fit and clearance issues.

Fluorosint™ 500 is also available in rod and tube form and can be machined according to customer specific drawings. 


Fluorosint™ 500 mica-filled PTFE sheet is used in many industries for sealing applications where chemical resistance, dimensional stability, low friction, and wear resistance are essential for successful operation. It is commonly used in aerospace applications and the food, drink, and pharmaceutical industries.
