Product description:

LQ-783 is a versatile UV stabilizer for thin and thick sections and delivers excellent cost/performance benefits. For applications requiring indirect food approvals, LQ-783 can be used at levels not possible with other conventional HALS. The synergism between the two high molecular weight HALS components of LQ-783 is an effective stabilization systems for the polymer against degradation through UV radiation and long term heat exposure.

Usage:

LQ-783 areas of application include polyolefins, loefin copolymers such as EVA as well as blends of polypropylene with elastomers.
