Plasticizers. Plasticizers ensure elasticity and flexibility of polymer materials. But this is not their only benefit. Plasticizers also optimize, for example, the processing properties of polymer materials, which leads to improved product quality or even new properties. The choice of plasticizers depends on the demand placed on the finished
Plasticiser loss from plastic or rubber products through
Polymers experience degradation during storage and service. One of the main degradation mechanisms of plasticised-polymer products is the loss of plasticiser, which leads to poorer mechanical
Polymers | Special Issue : Green Plasticizers for Polymers - MDPI
Reactive energetic plasticizers (REPs) coupled with hydroxy-telechelic poly (glycidyl azide- co -tetrahydrofuran) (PGT)-based energetic polyurethane (PU) binders for use in solid propellants and plastic-bonded explosives (PBXs) were investigated. The generation of gem -dinitro REPs along with a terminal alkyne stemmed from a series of [...]
Antiplasticization of Polymer Materials: Structural
A breakthrough for the use of plasticizers in polymers came with the advent of polyvinyl chloride ... solutions in methyl ethyl ketone, increases the modulus from 3 to 5 GPa at only 5 w% addition
Title: A Review on Plasticizers and Eco-Friendly
Plasticizers are chemical additives added into polymers to influence desirable mechanical properties such as processability and ductility. These properties are a result of the association of...
- Which polymers are plasticized?
- The plasticizers produced have been applied in 60 polymers and more than 30 groups of products. Industrially, the most common plasticized polymers are PVC, poly (vinyl butyral) (PVB), poly (vinyl acetate) (PVAc), acrylics, cellulose molding compounds, nylon, polyamides and certain copolyamides.
- How can plasticizers be used to make polymers soft and flexible?
- By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature. Plasticizers are classified according to their molecular structure into monomeric or polymeric types.
- Are biopolymers a good substitute for conventional plasticizers?
- The use of natural and/or biodegradable plasticizers, with low toxicity and good compatibility with several plastics, resins, rubber and elastomers in substitution of conventional plasticizers, such as phthalates and other synthetic conventional plasticizers attracted the market along with the increasing worldwide trend towards use of biopolymers.
- What materials use plasticizers?
- Many different materials use plasticizers — PVC, rubber, plastics and so on. In fact, the discovery of plasticizers pretty much made the polymer industry possible. Without a plasticizer, most polymers would just be too brittle and rigid to be useful.
- How do plasticizers affect polymers?
- Plasticizers are substances which, by virtue of their polar or polarizable structure, weaken the secondary valence forces of polymers. By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature.
- What types of plasticizers are used in hydrophilic polymers?
- In addition to water, the most commonly used plasticizers are polyols, mono-, di- and oligosaccharides. Polyols have been found to be particularly effective for use in plasticized hydrophilic polymers .
