Applications

• U-pack^® UV-783 is a synergistic mixture. It is a versatile UV stabilizer with outstanding extraction resistance, low gas fading and low pigment interaction.
• U-pack^® UV-783 is particularly well suited for LDPE, LLDPE, HDPE films, tapes and thick sections and for PP in fibers and films. It is also the product of choice for thick sections where indirect food contact approval is required.
• U-pack^® UV-783 is a versatile UV stabilizer for thin and thick sections and delivers excellent cost/performance benefits. For applications requiring indirect food approvals, U-pack^® UV-783 can be used at levels not possible with other conventional HALS. The synergism between the two high molecular weight HALS components of U-pack^® UV-783 is an effective stabilization system for the polymer against degradation through UV radiation and long-term heat exposure.
