Download our FREE Microwave Laminates Comparison Chart. Makes a great reference tool for engineers.
High temperature laminates are available through
the use of different resin
systems. Multifunctional epoxy, PPO, and polyimide are the most widely available.
Below is a chart of high temperature materials and their basic operating
properties.
Note: Values are for 0.059" thickness.
