PFA/FEP Encapsulated Core VMQ O-Ring

PFA/FEP Encapsulated Core VMQ O-Ring

FEP and PFA are very similar in their characteristics. PFA stands out for its greater thermal resistance at temperatures exceeding 200 °C. Thanks to the opportunities for combining two encasing materials and two core materials, the best possible encapsulated ring can be selected for a particular application. The formation of the inner elastomer as a hollow core expands the range of applications to uses that require relatively low contact forces. 

Advantages of FEP encapsulation

 • High resistance to numerous chemicals

 • High corrosion resistance 

 • Low compression set 

 • Low coefficient of friction 

Advantages of PFA encapsulation
