Stabilizer (chemistry)

In industrial chemistry, a stabilizer or stabiliser is a chemical that is used to prevent degradation.

• Representative stabilizers
• Tris(2,4-di-tert-butylphenyl)phosphite is a widely used stabilizer in polymers.
• Partial structure of typical hindered amine light stabilizers, widely used to protect automotive paints from degradation by UV-light.
• Salpn is a typical metal deactivator used as a fuel additive to suppress oxidation processes that lead to gums and solids. Metal deactivators like salpn form stable complexes with the metals, suppressing their catalytic activity.
