XX Phenolic


What is the Material: XX Phenolic is a thermoset material, which consists of a paper base filled with a phenolic resin.

Key Material Features: This material is beneficial in applications requiring electrical and mechanical strength.

Other Considerations: The more X’s, the better the electrical properties of paper phenolic, the fewer X’s represent better mechanical properties.
