Dioctyl terephthalate CAS 6422-86-2 DOTP

Availability:



Dioctyl terephthalate (DOTP) is an excellent main plasticizer for polyvinyl chloride (PVC) plastics. Compared with the commonly used diisooctyl phthalate (DOP), it has the advantages of heat resistance, cold resistance, volatilization resistance, extraction resistance, softness and electrical insulation properties, etc. It shows excellent durability, soap resistance and low softness and softness in the Chemicalbook products. Because of its low volatility, the use of DOTP can fully meet the temperature grade requirements of wire and cable, and can be widely used in cable material resistant to 70 ° C (International Electrotechnical Commission IEC standard) and other PVC soft products.

1. Performance and use:

DOTP can form a composite blend with polyaniline (PANI)-ethyene dimethacrylate (EDMA), which can be used in the fabrication of conductive films.

DOTP may also be used as a plasticizer with polyvinyl chloride (PVC) to form solutions for artificial intravessel plaque.

It is used primarily as a plasticizer for polyvinyl chloride and other polymers.

Dioctyl terephthalate, also known as DOTP, is used as a plasticizer in the production of PVC and other copolymers. It is the ester of terephthalic acid and 2-ethylhexanol. It is a clear, colourless liquid with a slight odour, which is insoluble in water. DOTP can be used as a direct replacement for DOP and DINP in a range of applications due to its thermal resistance, excellent durability and transparency. It is used in a variety of processes such as calendering, extrusion and injection molding.
