PEI Sheet & Rod

Sufoner® PEEK is a high temperature, high performance thermoplastic specialty engineering plastic. PEEK can be used continuously at 260 degrees without losing its physical and chemical properties. PEEK has extremely high stiffness and hardness, as well as unique high tensile strength and fatigue strength. In addition, its heat-resistant non-deformation performance and chemical stability are excellent.

Details about PEI Sheet & Rod

Sufoner® PEEK6000C and Sufoner® PEEK 6800CM
Sufoner® PEEK6000C and Sufoner® PEEK 6800CM are ideal for the semiconductor manufacturing industry to meet the requirements of precision microvia processing with a minimum pore size of 0.1mm or less.
Sufoner® PEEK6000C is a composite of polyetheretherketone PEEK and ceramic matrix. It has excellent processability, low cost, ultra-thin thickness (T1-5mm), high wear resistance, low thermal expansion, almost no burr machining, and is not easily deformed. High heat distortion temperature and very good thermal stability.

Special composite material Sufoner® PEEK 6800CM sheet
This material is a composite of PEEK and other custom formulated materials, which combines strength, stiffness and stability very well. The machining deformation is very small, the burr is very small, and the size is stable. It is especially suitable for high-precision applications. It is an ideal material for semiconductor test sockets, nests, fixtures and packaging equipment.
