Application of new oligomeric plasticizers based on waste
Various methods have been proposed to reduce the migration of plasticizers from PVCs using: (1) polymeric or oligomeric plasticizers, generally saturated polyesters [ 8] e.g., oligoisosorbide esters [ 9 ], (2) alternative to phthalates non-toxic plasticizers such as di (2-ethylhexyl) adipate, acetylated tributyl citrate [ 3 ], phenol alkyl
- What are alternative plasticizers for polyvinyl chloride (PVC)?
- Environmental and toxicity concerns dictate replacement of di (2-ethylhexyl) phthalate (DEHP) plasticizer used to impart flexibility and thermal stability to polyvinyl chloride (PVC). Potential alternatives to DEHP in PVC include diheptyl succinate (DHS), diethyl adipate (DEA), 1,4-butanediol dibenzoate (1,4-BDB), and dibutyl sebacate (DBS).
- How many DEHP molecules are there in a polyvinyl chloride (PVC) plasticizer?
- This system has 8 DEHP molecules, the diffusion of which are all tracked individually and then averaged to get the diffusion coefficients (red DEHP MSD line). Environmental and toxicity concerns dictate replacement of di (2-ethylhexyl) phthalate (DEHP) plasticizer used to impart flexibility and thermal stability to polyvinyl chloride (PVC).
- Which PVC plasticizer is most commonly used?
- Traditionally, phthalates are the most widely used PVC plasticizer. (1) In particular, PVC tubes using di (2-ethylhexyl) phthalate (DEHP) are used for external processing of blood and other bio-substances, presenting the concern that DEHP might leach into the blood to cause toxicity.
- Can PVC be a plasticizer?
- However, POSS can’t be as main plasticizer of PVC due to its limited miscibility with PVC. In order to improve compatibility of PVC and POSS systems, POSS and a little phthalates are used in PVC blends . PVC/methacryl-POSS systems containing 5 wt% DEHP appear to be transparent and homogeneous.
- Why do flexible PVC products need plasticizers?
- The properties of flexible PVC products significantly change with addition of plasticizers, such as reduction of the glass transition temperature (Tg) and tensile strength, while elongation will increase, which make PVC change from hard and brittle to flexible, thus greatly expand its application [, , ].
- Which plasticizer reduces Young's modulus of PVC?
- The E (x) of all plasticized systems converged as the temperature reached 500 K. DBS was the only plasticizer that consistently decreased the Young’s modulus of PVC as well as or better than DEHP (Figure 4). Figure 4. Predicted Young’s modulus for systems of PVC plasticized with DEHP, DBS, DHS, DEA, and 1,4-BDB at temperatures from 150 to 500 K.
