A Strategy for Nonmigrating Highly Plasticized PVC
Abstract. Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di (2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52
Effects of molecular design parameters on plasticizer performance
Abstract. Using all-atom molecular simulation, a wide range of plasticizers for poly (vinyl chlorid) (PVC), including ortho- and tere-phthalates, trimellitates, citrates, and various aliphatic dicarboxylates, are systematically studied. We focus on the effects of plasticizer molecular structure on its performance, as measured by performance
Energetic Polymers: Binders and Plasticizers for Enhancing Performance
This up-to-date overview provides the latest information on the performance, sensitivity, strength and processability aspects of propellants and explosive formulations, with the nature of polymer binder/plasticizer as the variable factor. Apart from applications, this monograph explores the principles behind energetic polymers, while discussing
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.
Plasticizer
Plasticizers for polymers are either liquids with low volatility or solids. According to 2017 data, the total global market for plasticizers was 7.5 million metric tonnes.
- Can plasticizers reduce material degradation over time?
- The design of new plasticizers compatible with the polymer at high concentrations, tailored to be effective in lowering the glass transition temperature, and with a low tendency to migration could considerably reduce material degradation over time.
- What makes a polymer a good plasticizer?
- It is nowadays established that good plasticization implies secondary bonds, also known as intermolecular forces, with the polymer. The attraction between plasticizer molecules and the polymer must be as strong as the interactions between molecules in the single components to generate an efficient polymer-plasticizer interaction.
- 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 .
- 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 semiconductor fluid molecular Plasticizers improve stretchable -conjugated polymer film?
- The realization of intrinsically stretchable fully π-conjugated polymer film is challenging due to their inherent brittle nature. Here, authors apply semiconductor fluid molecular plasticizers to improve stretchable deformability, achieving high performance flexible polymer light-emitting diodes.
- What are plasticizers used for?
- Plasticizers are an important class of low molecular weight non-volatile compounds that are widely used in polymer industries as additives . The primary role of such substances is to improve the flexibility and processability of polymers by lowering the second order transition temperature, the glass transition temperature (Tg).
