Simultaneous recovery of high-purity copper and polyvinyl
Herein, we introduce a combination of plasticizer extraction from polyvinyl chloride (PVC) and ball milling for the simultaneous, effective recovery of PVC and copper (Cu) from thin electric cables. PVC coverings typically contain plasticizers for flexibility. As such, PVC cables become brittle after plasticizer ex
Plasticizers: Types, Uses, Classification, Selection & Regulation
Plasticizers increase the flow and thermoplasticity of a polymer by decreasing the viscosity of the polymer melt, the glass transition temperature (Tg), the melting temperature (Tm) and the elastic modulus of the finished product without altering the fundamental chemical character of the plasticized material.
Borate ester plasticizer for PEO-based solid polymer
In this paper, we report the synthesis and characterization of a star-shaped borate ester plasticizer, which was then incorporated into the poly (ethylene oxide) polymer matrix in different proportions. Significant improvement was observed in conductivity, with the best value of 9.1 × 10 5 S/cm at 30 °C.
Simultaneous recovery of high-purity copper and polyvinyl
As a result, PVC is used in a wide variety of fields including the construction, automobile, electrical, medical, and daily goods industries.1 The global production of PVC reached 41420 kt in 2015,2 making it the third highest in volume among plastic resins.
Application of Carrier and Plasticizer to Improve the
The objective of this study was to develop a suitable formulation for baicalein (a poorly water-soluble drug exhibiting high melting point) to prepare solid dispersions using hot melt extrusion (HME). Proper carriers and plasticizers were selected by calculating the Hansen solubility parameters, evaluating melting processing condition, and measuring the solubility of obtained melts. The
- What is the best plasticizer for HTPB based solid propellants?
- Dioctyl adipate is compatible with many synthetic rubbers and shows good thermal stability. Isodecyl Pelargonate is considered as one of the best plasticizer in HTPB based solid propellants. It exhibits remarkably low viscosity and is suitable for use at low temperatures.
- What is a plasticizer used for?
- They are often applied to soften hard and brittle materials or facilitate processability of the material. Typically a plasticizer is a liquid of low volatility and high boiling point. Plasticizers are important ingredients in solid propellant and plastic explosives, where play a dual role.
- Do Plasticizers improve formulation performance and stability?
- Although these plasticizers are effective as processing aid for HME, the effect of these plasticizers on formulation performance and stability is of utmost interest for the development of stabilized amorphous formulations.

- What is a solid state plasticizer?
- Based on comparable solubility parameters, stearic acid, glyceryl behenate, and polyethylene glycol 8000 were selected as solid-state plasticizers. Binary and ternary physical mixtures were evaluated as a function of plasticizer concentration for thermal and rheological behavior.
- Which solid-state plasticizers are used in a chemistry study?
- Solubility parameters, thermal analysis, and rheological evaluation were used as assessment tools. Based on comparable solubility parameters, stearic acid, glyceryl behenate, and polyethylene glycol 8000 were selected as solid-state plasticizers.
- How to select solid-state plasticizer?
- The selection of solid-state plasticizer should include miscibility of plasticizer in polymer as well as API and its effect on T g and η 0 of the final system. It can be summarized that when components are miscible, different techniques will lead to the consistent plasticization effect prediction.
