Natural-based plasticizers and biopolymer films: A review
Plasticizers, for biopolymer-based lms, can be divided into water soluble and water insoluble [25]. The type and the amount of plasticizer strongly affect the lm formation from polymeric aqueous dispersions [26]. Hydrophilic plasticizers dissolve in the aqueous medium when they are added to polymer dispersions and if added in high con-
Highly efficient recovery of high-purity Cu, PVC, and phthalate
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 (PVC) coatings, and phthalate plasticizer in high purity.
The effect of glycerol concentration as a plasticizer on edible films
the highest thickness of edible film produced in this study still meets the requirements to be used as primary packaging material in foodstuffs. Tensile Strength Tensile strength is the maximum tensile force that can be held by a film. Edible films with high tensile strength are needed for food product packaging that aims to protect foodstuffs
Influence of Weather and Purity of Plasticizer on Degradation
Starch plasticized by glycerol is a key renewable resource in the production of high-quality bioplastics. Previous studies have availed information on the mechanical quality of starch-based bioplastics however there is limited information about their degradation pattern in the natural environment which this research presents.

- Are primary plasticizers good for Environmental Protection?
- Currently, the performance of primary plasticizers produced in China cannot fully satisfy the requirements for environmental protection, especially poor cleanliness and high toxicity. DOP and dioctyl adipate (DOA), especially the former, are the plasticizers widely used in PVC-based food wrap and packaging.
- What is the most widely used plasticizer in China?
- DOP is currently the most widely used plasticizer, ~70% of the total consumption of plasticizers. In China, the annual consumption is close to 1 million tons. In recent years, the medicine, food packaging, daily supplies, and toys industries have raised more stringent requirements to plasticizers.
- Which plasticizers are environmentally friendly?
- Currently, commercial environmentally friendly plasticizers include aliphatic acid esters, citrates, epoxy, terephthalates, high-carbon phthalate esters, cyclohexane dicarboxylates (or tetrahydrophthalates), polyesters, phenyl polycarboxylates, etc.
- What is a plasticizer?
- In general, plasticizers can be defined as low molecular weight (between 300 and 600) , high boiling point materials which are added to a film-forming polymer to enhance its flexibility, durability, processability, and workability . Their addition can avoid shrinking during storage , and in some cases reduce costs .
- What will China's plasticizer industry look like in the future?
- This will be the major task for Chinese plasticizer and soft PVC industries in the future. Phthalate plasticizers will still be the dominant type and production volume globally in the future, but those of long-chain (C 9 –C 10) alcohol-based esters and non-phthalate plasticizers will increase largely.
- Why are plasticizers important in biopolymer-based films & coatings production?
- In biopolymer-based films and coatings production, plasticizers are also essential additives since they can improve flexibility and handling of films, maintain integrity and avoid pores and cracks in the polymeric matrix .
