SUMIKAEXCEL PES has been used in a variety of electrical and electronic components due to its features such as low outgassing, dimensional stability, creep resistance and resistance to cleaning solvents:

Typical Applications in Electrical and Electronic Components

• Relay base
• Coil bobbin
• Movable plate (block of electrodes)
• Switch base
• Burn-in socket
• Connector
• Fuse case
• Cases and covers for various sensors
• IC Tray
• Printed circuit board
• , etc.

Burn-In Socket

These are sockets used for burn-in tests (tests that accelerate deterioration of electronic device samples by applying temperature and voltage loads to reduce initial defects), and test samples include semiconductors and memory modules. These take advantage of the excellent heat resistance, dimensional accuracy, and dimensional stability of SUMIKAEXCEL PES.

• SUMIKAEXCEL ES5340
  SUMIKAEXCEL ES5340 is an ultra-high flow grade that has improved flowability over 3601GL20.
• SUMIPLOY GS5620
  SUMIPLOY GS5620 is a low-wear, high-strength grade with improved sliding performance.
