Synthesis and properties of castor oil based plasticizers
Specifically, the tensile strength and elongation at break of a PVC sample plastified by epoxy acetylated castor oil (EACO) were 18.5 and 10.0% higher than that of DOTP, and 13.9 and 23.8% higher than that of ESO, respectively.
Synthesis and properties of castor oil based plasticizers
The modified epoxy acetylated castor oil (EACO) can plastify poly (vinyl chloride) (PVC) efficiently, even better than the commercial plasticizers dioctyl terephthalate (DOTP) and epoxidized soybean oil (ESO), in terms of in tensile strength, migration stability, solvent extraction stability and thermal stability.
Spectrophotometric characterization of plasticizer migration
Upon the increasing plasticizer content, tensile strengths of PVC films decreased. The tensile strengths of PVC films containing DOTP or TOTM are higher than those of PVC films containing other plasticizers at all three levels. The maximum tensile strengths of 16 ± 0.6 MPa and 16 ± 0.06 MPa were obtained with DOTP or TOTM at 40 phr.

PVC plasticizer: DOTP versus DOP. There is great controversy about the hazards that DOP plasticizer presumes and that is the reason producers are migrating towards the use of DOTP. Studies done to date have not really concluded DOP causing any disease in humans. Tests carried out on rodents at a higher dose and a long period of intravenous
DOTP Plasticizer for PVC-Processing - Extrusion
The official opening took place in May. DOTP is demand in the production of floor coverings, membranes, films, wallpaper and many other products, and from plasticized PVC. Accordingly, the types of processing can be different depending on the final product: extrusion, calendering, injection molding.
- What is DOTP & how does it work?
- The official opening took place in May. DOTP is demand in the production of floor coverings, membranes, films, wallpaper and many other products, and from plasticized PVC. Accordingly, the types of processing can be different depending on the final product: extrusion, calendering, injection molding.
- What is DOTP plasticizer?
- The main raw material for DOTP is terephthalic acid and this type of plasticizer fully complies with modern international requirements for the safety of chemical compounds. DOTP also has a number of advantages: • expansion of operating temperatures of cable products from -40 +70 to -45 +80 °C.
- Where is Dioctyl terephthalate plasticizer made?
- Denis Gerber: SIBUR Holding launched the production of dioctyl terephthalate plasticizer (DOTP) located on the territory of Sibur-Khimprom, Perm. The official opening took place in May. DOTP is demand in the production of floor coverings, membranes, films, wallpaper and many other products, and from plasticized PVC.
