CAS: 6422-86-2
Dioctyl Terephthalate (DOTP) is a High performance plasticizer derived from terephthalic acid- Superior the environmental footprint and volatility as compared to of plasticizers (e.g., phthalates) make it a more sustainable option for manufacturers than conventional plasticizers. DOTP has become a top alternative in the industry as safety and sustainability are top priorities for industries today offering versatility and toughness to different applications.
Properties of Dioctyl Terephthalate (DOTP):
CAS Number: 6422-86-2
Molecular Formula: C24H38O4
Melting Point: -48 °C
Density:0.986 g/cm³ @ Temp: 25 °C
Boiling Point: 383 °C @ Press: 760 Torr
Flash Point: 230 °F
Physical Properties
Appearance: Oily liquid, colorless or slightly yellowish.
Odor: Virtually odorless or with a faint ester-like scent.
Elevated viscosity: Room temp is high viscosity which gives a heavier oily consistency.
Solubility: Not soluble in water, slightly soluble in many organic solvents such as ethers and chloroform.
Compatibility: Works well with resins and polymers, especially PVC provides flexibility.
Chemical Stability: Stable to light, heat, and oxidation, enhancing the longevity of the final product.
Low Volatility: Vapour Pressure helps the aids long-term storage stability because it does not volatilize easily at normal temperatures.
Uses on Plastic & Rubber
DOTP is essential in the plastic and rubber industry as a plasticizer which affects the processability and end-properties of polymers. As use of it leads to enhanced flexibility, resilience and fading possibilities, it is a property DOTP has that makes it highly suitable for the manufacturing of sheet and films and range of flexible PVCs, flooring, wires and cables, etc.Applications in Other Industries:
Dioctyl Terephthalate (DOTP) of course is important in plastic and rubber, but the application has far more compartments than known:
Construction: DOTP working as a plasticizer in construction materials for the workability and long-life durability of properties for coatings , sealants etc.
HI&I cleaning products:Utilized in cleaning products to enhance flexibility and stability.
Pharma: DOTP improves the quality of packaging medical grade plastics.
Agriculture: Applied in agricultural films and coatings for better performance and longevity.
Automobile: It is typically used in automotive plastic parts and cable sheathing because of its thermal stability and chemical resistance (live many times longer in stressing automotive applications)
Paper and Coatings: DOTP is used in paper finishing, extrusion and molding and coatings. It also increases the quality of paints, varnishes and inks.
