Plasticizers mainly include phthalate esters, aliphatic dibasic acids, epoxy esters, chlorine-containing compounds and phosphate esters.

Phthalates: divided into DOP, DBP and DIDP.

Aliphatic dibasic acids: DOA, DOZ and DOS.

Epoxy ester: divided into ESO and ED3.

Chlorine-containing compounds: chlorinated paraffin (43%) has good fire resistance and electrical properties.

Phosphate ester: divided into TCP, TPP and TOP.

1. What are the main varieties of plasticizers?

1, phthalate

(1) Dioctyl phthalate (DOP): It has good compatibility, light stability, electrical insulation, low temperature resistance and low toxicity.

(2) Diethyl phthalate (DBP): It has the properties of good compatibility, good flexibility, low price and no use.

(3) Diisodecyl phthalate (DIDP): It has good heat resistance and electrical insulation.

(4) Uses: DOP, DBP and DIDP can all be used for films, plates and electrical insulation materials.

2. Aliphatic dibasic acids

(1) dioctyl adipate (DOA): Good low-temperature performance and poor compatibility.

(2) Dioctyl azelate (DOZ): It also has the properties of good low temperature and poor compatibility.

(3) dioctyl sebacate (DOS): Like the first two, it has good low-temperature performance and poor compatibility.

(4) Uses: DOA, DOZ and DOS can all be used for films, plates and electrical insulation materials.

3. Epoxy ester

(1) epoxidized soybean oil (ESO): It has good thermal stability, good volatility and no toxicity, and is often used in transparent products.

(2) Octyl epoxy stearate (ED3): It has good light stability and low temperature resistance, and is often used in agricultural films and plastic pastes.

4, chlorine-containing compounds

Chlorinated paraffin (43%) has the characteristics of fire resistance, good electrical performance, low price and no use, and is often used in cables and plates.

5. Phosphate ester

(1) Triphenyl phosphate (TCP): Good compatibility, good flame retardancy, poor low-temperature performance, toxic, commonly used in plates, cables and artificial leather.

(2) Triphenyl phosphate (TPP): It has good compatibility, good flame retardancy and cold resistance, and is often used in cables.

(3) trioctyl phosphate: Good compatibility, cold resistance, non-toxic, commonly used in films and plates.

6. Others

Petroleum phenyl carbonate (M-50) is an auxiliary plasticizer, which belongs to the general expected product.

Second, what is the main function of plasticizer?

1, plasticizer mainly weakens the secondary valence bond between resin molecules, increases the fluidity of resin molecular bonds, reduces the crystallinity of resin molecules and increases the plasticity of resin molecules. Enhance flexibility and facilitate processing.

2. Plasticizers can be used in industry and widely exist in food packaging, cosmetics, medical devices and environmental waters, such as plastic wrap and toys.
