What is UV 328 used for?

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.

What is tinuvin used for?

Tinuvin® for Plastics. BASF’s light stabilizers Tinuvin ® protect plastics parts against all sorts of weather conditions that lead to loss of mechanical properties and discoloration of surfaces.

What is tinuvin P?

Product Description Tinuvin P is an ultraviolet light absorber (UVA) of the hydroxyphenyl benzotriazole class, imparting good light stability to a wide variety of polymers. Key Features & Benefits. – Strong absorption of UV radiation in the 300 – 400 nm range. – Photo-stability over long periods of light exposure.

What Tinuvin 292?

Product Description Tinuvin 292 is a liquid hindered amine light stabilizer especially developed for coatings. It is an almost pure mixture of the two active ingredients below. It is this combination that keeps the product liquid, unlike the pure diester which tends to solidify, even at room temperature.

How does UV absorber work?

UV absorbers, work by targeting the incident radiation before it prevents any initial degradation. The absorb the highly energetic UV light and re-emit it at a lower energy state thereby dissipating the energy in a less dangerous form. The most important class of UV absorbers are the hydroxybenzophenones.

What is UV stabilizer?

UV stabilizers are substances that are used to prevent a chemical process referred to as “photo degradation” which occurs when ultraviolet radiation coming from an artificial light source or the Sun collapses chemical bonds within a polymer.

What Irganox 1010?

Product Description Irganox1010 is a highly effective, non-discoloring, sterically hindered primary phenolic antioxidant stabilizer that protects organic substrates against thermo-oxidative degradation.

Are UV stabilizers toxic?

Currently, it lists four benzotriazole UV stabilizers as Substances of Very High Concern (SVHC) due to persistent, bioaccumulative and toxic (PBT) properties (ECHA, 2018a).

What type of light is UV?

electromagnetic radiation
Ultraviolet (UV) “light” is a type of electromagnetic radiation. UV light has a shorter wavelength than visible light.

What is the difference between UV stabilized and UV resistant?

UV Stabilized means they have added a stabilizer to the resin to allow it to protect the substance from the long-term degradation from UV light. UV stabilizers work by absorbing or screening out UV radiation and preventing damage. UV Resistant materials by nature resists UV rays and prevent UV degradation.

What is UV additive?

UV stabilization additives are chemical compounds that are added to combat the deterioration of the plastic and significantly extend the life span of the final product. UV stabilizers are added at very low levels, often 0.1 – 0.5% of the polymer.
