PEEK with defined electrostatic dissipative properties

PEEK SD is an electrically modified PEEK ESD plastic material with a defined surface resistance between 106 -109 Ohm. Due to its electrostatic dissipation properties, this material is commonly used in applications within the electronics industry, test sockets being one example. Such materials are also referred to as ESD safe materials. PEEK ESD has excellent dimensional stability and can be machined easily to very tight tolerances. Static plastic, such as PEEK ESD, is increasingly used in the electronics industry due to increasing requirements for temperature and chemical resistance.
