company news about Preventing Yellowing in Light-Colored ABS

Light-colored ABS (white, beige, gray) is prone to yellowing due to unsaturated double bonds in its molecular chain, which degrade under light, heat, and oxygen exposure. This weathering issue affects aesthetics and customer satisfaction, especially in applications like家电 casings and automotive trims.

Strategies to mitigate yellowing include:

Using UV stabilizers and antioxidants

Selecting ABS grades with enhanced weatherability

Optimizing processing conditions to minimize thermal degradation

Applying protective coatings or color-stable masterbatches
