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.
Polyelectrolytes are made up of positively or negatively charged repeat units.The charge on a polyelectrolyte depends on the different properties of the solution, such as the degree of dissociation of the monomer units, the solvent properties, salt concentration, pH, and temperature.
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 ...
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]
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.

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]
Drilling stabilizer, part of the bottom hole assembly in oil drilling; Gyroscopic stabilizer (disambiguation), on ships and aircraft; Gun stabilizer, or gyrostabilizer, a device that helps a moving tank's gunner to aim the gun; Sway bar, a bar linking the two sides of an automotive suspension; Stabilization pond, a way of stabilizing wastewater
A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. [1] When chemical reactions occur, the atoms are rearranged and the reaction is accompanied by an energy change as new products are generated.
