Methods for determination of plasticizer migration
To impart the PVC coating with flexibility and bendability, a substantial amount (40–120 wt%) of plasticizers must be added. Plasticizer acts like a lubricant that intercalates the rigid PVC chains for an easy movement, otherwise pristine PVC would be too brittle for any practical purpose.
A simple approach with scale-up potential towards
Abstract As an imitation of genuine leather, polyvinyl chloride (PVC) artificial materials are versatile, but suffers from being flammable due to the presence of large amounts of combustible plasticizers. Under such circumstance, intrinsically flame-retardant plasticizers displaying dual functions have been a subject of intensive research interest. However, previous strategies attempting to

Plasticizers: Types, Uses, Classification, Selection & Regulation
Incorporation of an external plasticizer in PVC polymer enhances its flexibility. Addition of plasticizer chiefly involves five distinct steps: Plasticizer mixed with resin Plasticizer penetrates and swells the resin particles Polar groups in the PVC resin are freed from each other
- How do plasticizers affect the migration rate of PVC artifical leather?
- According to lightness change on the surface of PVC artifical leather before and after heat treatment at 70 °C, the migration rates of used plasticizers increase in this order: TOTM < TBTM < DOTP < BIO < DOA. Artificial leather has similar appearance and durability with real leather at lower cost.
- Which material is used to make artificial leather?
- Polyvinyl chloride (PVC) is one of the most employed thermoplastic material to produce artificial leather [1,2]. Since pure PVC has relatively rigid and brittle features, plasticizers are added to PVC to obtain the desired durability and flexibility .
- What is PVC based artificial leather?
- Polyvinyl chloride (PVC) is a primary component with production of artificial leather which can remarks on the cost-effectiveness, durability, and flexibility. The paper discusses the essential raw material used in manufacturing process of PVC based artificial leather and their functions.
- Why is PVC a preferred base polymer in artificial leather production?
- According to Braun (2008) have covered the PVC intrinsic properties to tailor on the resistance and flexibility and durability were preferred base polymers in artificial leather production. PVCs has achieved on the specific performance characteristics desired in the artificial leather.
- Do plasticizers migrate from PVC?
- These additives are supposed to stay in PVC for permanent flexibility, but unfortunately, they continue migrating from the coating matrix, leading to a series of consequences. A range of analytical methods for the determination of plasticizer migration from PVC synthetic materials is now available.
- Is there a bio-based plasticizer for poly (vinyl chloride)?
- An efficient bio-based plasticizer for poly (vinyl chloride) from waste cooking oil and citric acid: synthesis and evaluation in PVC films. J Clean Prod. 2018;189:334–43.
