SELECTION CONDITIONS FOR LIGHT STABILIZERS (UV STABILIZER) AND FACTORS AFFECTING UV STABILITY

Considerations when selecting a light stabilizer (UV Stabilizer)

We select a light stabilizer with a low unit cost by comparing price and performance.

Check compatibility with plastics. Poor compatibility can cause whitening, surface roughening and premature oxidation.

If the molecular weight of the light stabilizer is too large, surface transferability will decrease and cause premature oxidation.

Heat resistance is checked to avoid causing color and odor during processing or use of the final product. If heat resistance is low, it may volatilize during the process, causing environmental pollution, and frequent cleaning and breakdown of processing equipment. Car interior materials create a unique odor inside the vehicle.

In the case of UV absorbers, they protect plastic by absorbing UV light over a wide range.

In order to develop consistent colors when compounding various colors, the light stabilizer must have low color variation and have its own UV stability.

It has a product form that considers low toxicity, worker safety, and the environment.

Depending on the intended use, various functional additives and their possible adverse effects are considered.

Follow laws and regulations depending on the area of application. (e.g. FDA, VOC, etc.)

Choose a trustworthy provider.
