Developments of biobased plasticizers for compostable
The development and utilization of biobased plasticizers derived from epoxidized soybean oil, castor oil, cardanol, citrate, and isosorbide have been broadly investigated. The synthesis of...
Highly efficient recovery of high-purity Cu, PVC, and
Novel methods for recycling waste wire harnesses, namely, dry rod milling (which involves the swelling of the cables followed by milling) and wet rod milling (which involves the simultaneous swelling and milling of the cables), were developed for the simultaneous recovery of the Cu wires, polyvinyl chloride

- What is a primary plasticizer?
- A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.
- What are natural product type plasticizers?
- Vegetable oil derivatives are the most widely used natural product type plasticizers. Products consisting of triglyceride esters of unsaturated fatty acids (e.g., soybean oil, linseed oil) in which the double bonds in the fatty acid residues have typically been epoxidized have been commercial products for decades.
- What is a polymeric plasticizer?
- Polymeric plasticizers are typically made from aliphatic dibasic acids such as adipic acid and diols. They are primarily valued for their permanence. These plasticizers are generally classified as polyesters, not adipates. Many have low solvency for PVC and high viscosity. Both these factors can make processing f-PVC compounds difficult.
- Which phthalate is used as a plasticizer for PVC?
- DTDP is the highest weight dialkyl phthalate to be used as a plasticizer. It was widely used as a high temperature plasticizer for PVC until trimellitates came into existence. It needs high processing temperatures for compounding with PVC. Cost: Phthalates are used as PVC plasticizers since the earliest days of flexible PVC.
- How to choose a general-purpose plasticizer for PVC?
- While selecting a general-purpose plasticizer for PVC, the main attributes to be checked are: Among them, regulation is an important decision factor while selecting plasticizers. In recent years, there has been a lot of discussion on phthalate plasticizers. But in fact, not all phthalates are prohibited.
- Are phosphates a good plasticizer for PVC?
- Phosphates are primary plasticizers for PVC. They can be utilized as sole plasticizers or in a cost-optimized blend. Triaryl phosphates show excellent flame retardancy with low volatility. However, they have poorer low-temperature flexibility.
