EPPE: Precision and safety with expanded polyphenyl ether

Expanded polyphenyl ether (EPPE) is an innovative, lightweight particle foam that offers a wide range of benefits. With an excellent thermal insulation of only 0.034 W/(m*K) at a density of 100 g/l and a temperature resistance of up to 130 °C, it is ideal for demanding electronics applications that protect foamed-in electronics. EPPE is also used in the mobility industry and in stationary applications where fire protection and precision are crucial. Its flame-retardant properties and excellent flame resistance ensure a high level of safety: EPPE achieves UL94 V-0 classification – without the use of halogenated flame retardants.

In addition, EPPE enables thin-walled and precise shaping. Another advantage is its high resistance to chemicals, including aggressive substances such as acids and solvents.
