5) uses

Octabenzone (CAS NO.1843-05-6) can be used to protect polymers (e.g., polyethylene, polypropylene, polyvinylchloride) against damage by UV light. Octabenzone is a light stabilizer agent with good performance,capable of absorbing the UV radiation of 240-340 nm avelength with the characteristics of light color,nontoxic,good compatibility,small mobility,easy processing etc. It can protect the polymer to its maximum extent,helps to reduce the color.It can also delay the yellowing and obstacle the oss of its physical function.
