Plasticizers & Phthalates Standards

Plasticizers and Phthalates Standards

Plasticizer refers to the substance added to the polymer system to increase the plasticity of the system. The mechanism of action is to increase the mobility of polymer molecules by weakening the force between polymer molecules. According to the chemical structure of plasticizers, it can be divided into phthalates, chlorine-containing plasticizers, phenyl alkyl sulfonates, polyol esters, aliphatic tribasic acid esters, epoxy esters, phosphate esters, trimellitate esters and others. Among them, phthalate is a commonly used plasticizer in plastic products, widely used in in toys, food packaging bags, wallpaper, medical blood bags, medical hoses, detergents and many other products.

Studies have shown that the phthalate content exceeding the standard will cause great harm to human health. Therefore, for products containing plasticizers, standard reagents need to be formulated for content, use and recycling methods.
