In industrial chemistry, a stabilizer or stabiliser is a chemical that is used to prevent degradation. [1] Above all, heat and light stabilizers are added to plastic and rubber materials because they ensure safe processing and protect products against aging and weathering.
4-Vinylbenzyl chloride is an organic compound with the formula ClCH 2 C 6 H 4 CH=CH 2. It is a bifunctional molecule, featuring both vinyl and a benzylic chloride functional groups . It is a colorless liquid that is typically stored with a stabilizer to suppress polymerization.
Hexachloroethane (perchloroethane) is an organochlorine compound with the chemical formula (CCl 3) 2. It is a white or colorless solid at room temperature with a camphor-like odor. [ 3 ] It has been used by the military in smoke compositions , such as base-eject smoke munitions ( smoke grenades ).
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

Theoretical chemistry requires quantities from core physics, such as time, volume, temperature, and pressure.But the highly quantitative nature of physical chemistry, in a more specialized way than core physics, uses molar amounts of substance rather than simply counting numbers; this leads to the specialized definitions in this article.
Light stabilizer are used to inhibit polymer photo-oxidation, which is the combined result of the action of light and oxygen. Like autoxidation this is a free radical process, hence the antioxidants described above are effective inhibiting agents, however additional classes of additives are also beneficial, such as UV absorbers, quenchers of ...
Sodium stannate, formally sodium hexahydroxostannate(IV), is the inorganic compound with the formula Na 2 [Sn(OH) 6].This colourless salt forms upon dissolving metallic tin or tin(IV) oxide in sodium hydroxide and is used as a stabiliser for hydrogen peroxide. [2]
It is added as a stabilizer and polymerisation inhibitor to butadiene, styrene, [5] vinyl acetate, divinylbenzene [6] and other reactive monomer streams. [7] TBC is also used as a stabilizer in the manufacture of polyurethane foam. [8] It also can be used as an antioxidant for synthetic rubber, polymers and oil derivatives. [7]
