What is a plasticizer (Phthalate ester)?

Phthalate esters refer to the esterified derivatives of phthalate acid, and are the most common plasticizers in the plastics industry. The so-called plasticizer refers to: during the processing of plastic raw materials, the addition of plasticizer can change the physical properties of the plastic during forming, making the physical properties softer and easier to process; or adding plasticizers can make the plastic The finished product is soft, easy to bend and fold. Phthalate ester plasticizer (Phthalate ester) is a colorless liquid with a slight aromatic odor or odorless, medium viscosity, high stability, low volatility, easy to obtain, low cost and long experience in the industry. It is very soluble in water Small and easily soluble in most organic solvents.

Harm to the body:

According to foreign research, in addition to being released into the environment during the production process, using or adding to polyvinyl chloride (PVC), phthalate substances can also be released from waste plastics in landfills and borrowed from them. It is adsorbed on the bottom mud or organic humus and dispersed to the environment, and can enter the human body through food, air inhalation, etc. Since "phthalate" is an environmental hormone, it is a chemical substance that interferes with the secretion of organisms.
When environmental hormones enter the body, they can cause endocrine disorders, hinder the reproductive function of the organism, cause malignant tumors, and easily cause deformities. It has been proven that being in an environment with phthalates for a long time may cause asthma and suffer from toxic polyangeritis; after entering the body, 90% are excreted in urine or excreta, but still part of it passes through the body. Biodegradation and absorption into the body from the liver, intestines, stomach and kidneys are still quite harmful to the body.

General application:

Plastic, this man-made substance closely related to our daily life, has good ductility and stable physical and chemical properties by adding phthalate plasticizers, so it is widely used in food packaging, food containers, and consumer products. Products, medical products, materials for transportation vehicles, furniture and equipment, clothing, construction materials, nail polish, cosmetics, hair sprays, dyes, PVC flooring, carpet underlays, artificial leather and some adhesives. It is widely added to the production of polymer plastic products in daily and industrial fields, such as polyvinyl chloride (PVC), polypropylene (PP), foam, and can also be added to adhesives, coatings, and inks.
