Polycarbonate (PC) Stabilization Solutions

Protect Polycarbonate Against Heat, UV and Long-Term Aging

Polycarbonate (PC) is valued for its exceptional transparency, impact strength and dimensional stability. It is widely used in automotive lighting, optical lenses, electronic housings, construction panels and consumer electronics. However, prolonged exposure to heat and ultraviolet radiation can lead to yellowing, loss of transparency, surface cracking and reduced mechanical performance.

Yihoo Polymer provides advanced stabilization solutions that help PC manufacturers maintain optical clarity, improve processing stability and extend product service life.
