    Antioxidants - Polymer Additives Selection - SpecialChem

    This fact has led to the development of specific additives that can be used with high temperature polymers. This guide will review the three main high heat additives: antioxidants, flame retardants and processing aids used with high heat polymers. Read on and uncover the features they offer in several high temperature polymers.

    Antioxidants & UV: polymer additives - phosphites - Betaquímica

    Organic materials such as polymers, both of synthetic and natural origin, are exposed to oxidation reactions. It is important to be aware of this because a degradation of the polymer can modify or cause the loss of its mechanical properties, the breaking stress, surface roughness, discoloration, degradation of the chain, etc. may appear.

    Determination of polymer additives-antioxidants

    An analytical method for the quantitative determination of migration levels of polymer additives such as antioxidants and UV absorbers in food packages by high-performance liquid chromatography coupled with UV-vis photodiode array detection has been developed. The pretreatment step involved solid-phase extraction with silica C18 cartridges. The analytical method showed good linearity
