Tinuvin XT 833 is a novel high performance light stabilizer system that imparts outstanding weatherability to PVC and to PVC alloys. The primary advantage of this product over the more traditional ultraviolet absorbers typically added to exterior PVC is the superior color and physical property retention that it provides.

Applications

The use of Tinuvin XT 833 is especially recommended for applications like PVC roofing membranes, PVC pond, pool, and irrigation liners, PVC coated fabrics such as those used in tents, tarps, and awnings, flexible PVC outdoor furniture, PVC flooring, PVC automotive trim, and in other flexible PVC outdoor applications. It can also be used in rigid PVC formulations, especially those that do not contain tin mercaptide thermal stabilizers. Some of the applications include dark colored PVC siding and pigmented window and door profiles. Additionally, it can be used in PVC alloys like PVC/ABS and PVC/PUR for parts exposed to sunlight.

Features & Benefits

This product is a powerful ultraviolet light stabilizer that maintains its activity in highly acidic environments. It protects PVC from the harmful effects of light exposure and helps it to maintain its initial appearance, its initial tensile, elongation, and impact properties, and its physical integrity during long-term weathering. In PVC roofing membranes, for example, it minimizes discoloration and embrittlement and enables the membranes to retain their moisture barrier properties and their reflectivity for many years. A similar appearance and physical property protection is provided by Tinuvin XT 833 in other outdoor PVC applications
