Polyphenylene ether used for copper clad laminate

Polyphenylene ether resins (PPO) are widely used in the manufacture of
copper-clad laminates (CCL) and printed circuit boards (PCB), mainly due to
their excellent insulating properties, heat resistance and mechanical
strength. PPO resins not only improve the dielectric and mechanical
properties of CCLs, but also enhance their dimensional stability and low
water absorption.
Application of Polyphenylene Ether Resin in Copper Clad Laminate and Its
Advantages
The application of polyphenylene ether resin in copper-clad laminates is
mainly reflected in its excellent performance:
Insulation performance: Polyphenylene ether resin has low dielectric constant
and dielectric loss, which can effectively reduce the interference and loss
in signal transmission.
Mechanical properties: the modified PPE resin can significantly improve the
mechanical strength and dimensional stability of copper-clad laminates,
ensuring stable performance in high-frequency applications.
Thermal performance: Polyphenylene ether resins can maintain stable
performance at high temperatures, which is suitable for high-frequency
copper-clad laminates.
