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.
A Strategy for Nonmigrating Highly Plasticized PVC
The as-prepared PVC has a plasticizing efficiency as high as DOP and its migration is totally suppressed. Unlike other reported methods, this approach increases the interaction between phthalate...
Plasticizers – Benefits, Trends, Health, and Environmental Issues
Plasticizers are colorless and odorless esters, mainly phthalates, that increase the elasticity of a material (e.g., polyvinylchloride (PVC)). Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications. One of the main benefits of plasticizers is the durability they confer onto
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-
Plasticizer - an overview | ScienceDirect Topics
10.1.3 Plasticizer. Plasticizers are general colorless liquids which are relatively nonvolatile. Most of the plasticizers used for carpets are esters of phthalic acids (phthalates) with a wide variety of long chain alcohols. Plasticizers are classified according to function or structure.
- Are bio-based plasticizers a good choice for a fast fuser?
- Furthermore, a range of performance tests enabled an insight into structure-performance relationships and revealed promising plasticizing properties of this new bio-based plasticizer generation with, e. g., an attractive solution temperature fulfilling the criterium for a “fast fuser” as well as good compatibility with PVC.
- Which plasticizer has a strong migration resistance?
- Hyperbranched plasticizer has strong migration resistance due to its unique structure. Lactic acid-based plasticizers are a very cutting-edge direction that requires more research and development. These bio-based plasticizers can give PVC materials excellent thermal and mechanical properties under the premise of resistance to migration.
- Which plasticizer has a good plasticizing efficiency?
- Both plasticizers provided a satisfactory plasticizing efficiency, such as DEP, due to their low viscosity and ease of diffusion into CA, which enables a large processing window and increases the material's flexibility. CA with 30 wt% GTA displayed a slightly higher elastic modulus than CA with 30 wt% GDA (E = 2.1 GPa and 1.9 GPa, respectively).
- Can polar groups improve plasticizer performance?
- Studies have shown that relatively more polar groups can improve the performance of plasticizers. Therefore, some researchers have used these existing groups to introduce extra polar groups on the castor oil molecular to make it more suitable for plasticizers [34, 35, 36, 37].
- What is the best plasticizer for PVC films?
- Thermal and mechanical properties of PVC films are shown in Table 1. For PVC, AcMAE-C6 was found to be the most effective plasticizer (780%), followed by AcMAE-C8 (757%), AcMAE-iC8 (729%), AcMAE-iC13 (595%), and AcMAE-C4 (477%). The results showed that AcMAE-C6 and AcMAE-C8 showed better plasticizing properties than DOA and DEHP.
- What happens when plasticizers are introduced into PVC gel?
- The introduction of plasticizers into PVC results in a transition from rigid PVC (solid) to soft PVC gel (colloid). In pure PVC gel, the PVC molecular chains form the internal network skeleton, restrict the migration of plasticizers, and provide a stable cross-linked structure .
