UV-328 is a light stabilizer for a variety of plastics and other organic substrates. Its use is recommended for the stabilization of styrene homopolymers and copolymers , acrylic polymers, unsaturated polyesters , polyvinyl chloride , polyolefins , polyurethanes , polyacetals , polyvinyl butyral , elastomers and adhesives .

2-(2-Hydroxyphenyl)-2H-benzotriazoles, also referred to as phenolic benzotriazoles, are an important class of UV absorbers [1] comprising the benzotriazole building block. Structure [ edit ]
Hindered amine light stabilizers (HALS) are chemical compounds containing an amine functional group that are used as stabilizers in plastics and polymers. [1] These compounds are typically derivatives of tetramethylpiperidine and are primarily used to protect the polymers from the effects of photo-oxidation; as opposed to other forms of polymer degradation such as ozonolysis.
[232] [233] [234] When anime is defined as a "style" rather than as a national product, it leaves open the possibility of anime being produced in other countries, [230] but this has been contentious amongst fans, with John Oppliger stating, "The insistence on referring to original American art as Japanese "anime" or "manga" robs the work of its ...
Polymer stabilizers (British English: polymer stabilisers) are chemical additives which may be added to polymeric materials to inhibit or retard their degradation. Mainly they protect plastic and rubber products against heat, oxidation, and UV light.

Concentrations normally range from 0.05% to 2%, with some applications up to 5%. Frequently, glass can be a better alternative to polymers when it comes to UV degradation. Most of the commonly used glass types are highly resistant to UV radiation. Explosion protection lamps for oil rigs for example can be made either from polymer or glass. Here ...
