Product Description

CHARACTER

dioctyl phthalate (DOP), chemical formula C24H38O4, is a colorless transparent liquid, commonly used as a plasticizer. It has excellent comprehensive properties, such as low volatility, strong resistance to ultraviolet light, good flexibility, cold resistance and excellent electrical properties. DOP has good compatibility with polyvinyl chloride (PVC), ABS resin, acetate resin and rubber, and is widely used in plastics, rubber, paint and emulsifier industries. As a plasticizer, DOP can effectively improve the softness, cold resistance and processing performance of PVC products, and is used in the manufacture of artificial leather, agricultural films, packaging materials, cables and other products. In addition, DOP also has good electrical properties and can be used to produce electrical products such as wires and cables.

APPLICATIONS

(1) In the plastics industry, DOP is one of the most widely used plasticizers, mainly used in the processing of polyvinyl chloride (PVC). By adding DOP, the flexibility, wear resistance and aging resistance of PVC materials are significantly improved, making it suitable for the manufacture of various soft plastic products, such as artificial leather, agricultural films, packaging materials, cables and wires.

(2) In the rubber industry, DOP is also used as a plasticizer to improve the softness and elasticity of rubber. It plays an important role in the manufacture of synthetic rubber and natural rubber products, such as automobile sealing strips, rubber gaskets and rubber tubes.

(3)DOP can also be used in coatings and paints, mainly to improve the flexibility and gloss of the coating. It can enhance the adhesion and durability of the coating, making it widely used in architectural coatings and industrial coatings.

(4) In the field of adhesives and sealants, DOP as a plasticizer can improve the softness and adhesion of products, making it play a key role in construction, automotive and electronic products.

(5)DOP is also used as a solvent and gas chromatography stationary liquid, and has a wide range of applications in the chemical industry.

(6) In addition, DOP is also used to test the filtration efficiency of high-efficiency filters. Because 0.3 microns is the particle size with the largest penetration rate for high-efficiency filters, DOP is used to test the performance of high-efficiency filters.
