DOP 디옥틸 프탈레이트, 전체 이름 디옥틸 프탈레이트, is a 일반적으로 사용 가소제 with a 화학 공식 of C24H38O4. In its molecular structure, there are two ester groups that interact with each other through the conjugation of phthalic acid. It is a 무색, 투명 액체 with 양호 용해도 및 가소성 특성. It is 자주 사용 as a 가소제 for various synthetic resins such as PVC (폴리비닐 클로라이드). 그것 할 수 있다 개선 유연성 및 가공성 의 플라스틱 통해 용해 및 침투.
DOP dioctyl phthalate is the most widely used plasticizer. In addition to cellulose acetate and polyvinyl acetate, it has good compatibility with most synthetic resins and rubbers used in the industry. This product has good comprehensive properties, good mixing properties, high plasticizing efficiency, low volatility, good low-temperature flexibility, water extraction resistance, high electrical properties, good heat resistance and weather resistance. As a main plasticizer, this product is widely used in the processing of various soft products of polyvinyl chloride, such as films, sheets, artificial leather, cable materials, and molded products. This product is non-toxic and can be used for packaging materials in contact with food, but it is not suitable for fatty food packaging materials because it is easily extracted by fat. It can also be used in nitrocellulose paint to make the paint film have elasticity and high tensile strength. Among various synthetic rubbers, DOP dioctyl phthalate also has a good softening effect. In addition, DOP is also used as a condensing agent, antifriction agent, organic solvent, gas chromatography stationary liquid, etc.
