Automotive & Transportation

Rianlon leverages its extensive customer base and deep industry expertise to deliver comprehensive anti-aging solution systems for the automotive sector.

The Rapid Development of the Automotive and Transportation Industry Has Created Growing Demands for Advanced Anti-Aging Performance

With increasing importance in weight reduction of automobiles, polymers are used extensively in both interior and exterior automotive components. These materials help reduce energy use and improve design. However, exposure to light, heat, moisture, and oxygen can lead to photo-thermal aging, which may degrade appearance or impair performance.
