Background

Phthalate esters, also known as phthalates, are a generic term for esters formed from phthalic acid. When used as a plasticizer for plastics, it is generally an ester of phthalic acid with a C4-15 alcohol. Phthalate esters are of a large variety (about 30 or more), with dioctyl phthalate being the most important. Is considered to be an environmental hormone ubiquitous in the living environment. Phthalate compounds are fat-soluble compounds, and are used for packaging butter and animal fat foods in plastic bags, especially when the foods are hot, so that the intake of the human body is increased, and the health is not facilitated.

The novel slow-release material has diversified forming methods and rich application forms.
