Introduction to TPU-Specific Light Stabilizer

A high-efficiency light stabilizer specifically developed for polyurethanes, suitable for all types of polyurethane products and especially for TPU. The advantages of Tiangang light stabilizers lie in their low initial yellowness, excellent resistance to aging and color fastness, superior processing performance, and synergy.

II. Comparative Testing

1. Comparison of Initial Yellowness

Light stabilizers have a certain influence on the initial color of a product, which is reflected in the sample's initial yellowness; this effect is particularly noticeable in light-colored and transparent materials.

As shown in Fig. 1, the photos of the initial panels of samples with different formulations show that Sunnowin® 5566 is visually close to the competitive product and the blank sample, whereas the traditional formulation (SOA combination) shows noticeably more initial yellowing.

2. Comparison of Light Stabilization Effect
