On August 27, Wanhua Chemical and Geely Automobile jointly announced the cooperation results on automotive-grade light-guiding polycarbonate (PC) materials at Wanhua Chemical's Ningbo Research Institute, with senior executives from both sides attending the ceremony.This collaboration marks Wanhua Chemical as the first Chinese company to enter the core supply chain of light-guiding materials for Geely Auto's car lights.

As the core optical material for automotive lighting, its performance directly determines the safety and reliability of intelligent automotive lighting systems—not only must it possess the optical “hard indicators” of ultra-high transmittance, low haze, low birefringence, and resistance to yellowing, but it must also meet the physical “hard requirements” of high flowability, high impact resistance, and high heat resistance. Through independent research and development of the interfacial polycondensation phosgenation process, Wanhua Chemical has made breakthroughs in raw material formulation, additive optimization, and production processes, launching…Automotive-grade light guide PC material Clarnate^® LED1355This material addresses the challenges of PC yellowing by optimizing the polymerization process, significantly enhancing product purity and anti-aging performance, achieving industry-leading levels in optical properties, processing stability, and long-term weather resistance.

Geely Automobile's technical team simultaneously overcame challenges in material forming processes. Through precision injection molding and optical calibration technologies, they successfully…Materials are applied to the lamp group design of several models such as Zeekr and Geely.Create a unique visual effect that combines a sense of technology with Eastern aesthetics.

This collaboration is not only a breakthrough in the industrialization of independently developed materials by Wanhua Chemical but also a key advancement in the light guide technology for Geely's domestic car lights. It also establishes a new paradigm of collaborative innovation in the local industry chain, both upstream and downstream. The cooperation deeply aligns with Geely's philosophy of "creating intelligent quality cars for everyone" and Wanhua Chemical's corporate mission of "Chemistry, making life better!" In the future, both parties will continue to deepen their innovative collaboration and join hands to create a brighter future for the Chinese automotive industry chain.
