How to Select the Right Plasticizer for Polymers?
Plasticizers are the major functional additivestransforming the physical properties of polymers such as PVC, PU, acrylic, nitrile and rubbers to create a whole world of flexible and durable finished articles for high demanding applications. The world plasticizer consumption was around 7.82 million MT in 2017, up nearly 25% over 6 years[2].
Deep Dive into Plastic Monomers, Additives, and Processing
We systematically investigate plastic monomers, additives, and processing aids on the global market based on a review of 63 industrial, scientific, and regulatory data sources. In total, we identify more than 10'000 relevant substances and categorize them based on substance types, use patterns, and hazard classifications wherever possible.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Plasticizers increase the flow and thermoplasticity of a polymer by decreasing the viscosity of the polymer melt. Most common plasticiser chemistries include citrates, benzoates, ortho-phthalates, terephthalates, adipates, azelates, sebacates, and trimellitates. Plasticizers are the most common additives used in the plastics industry.
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 [...]
- Are secondary plasticizers compatible with polymers?
- Since the primary plasticizers can quickly gel the polymer and have solubilities close to those for the polymer, they rarely leach out of the plasticized material. The secondary plasticizers group’s compatibility with polymers is generally quite limited.
- What is a plasticizer chemistry?
- Plasticizers are the most used additives in the plastics industry. They are generally available as non-volatile, colorless liquids. They improve the properties of the polymer. With several plasticizer chemistries available in the market choosing the right one can be daunting. In this guide, you will read more about:
- What are the characteristics of polymer additives?
- This review presents some of the main characteristics of common polymer additives, such as antioxidants, antistatic agents and plasticizers, and recent research in developing bio-alternatives.
- 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.
- How do you plasticize a polymer?
- A polymer can be internally plasticized by chemically modifying the polymer or monomer. This increases flexibility. It involves copolymerization of the monomers of the desired polymer (having high Tg) and that of the plasticizer (having low Tg) so that the plasticizer is an integral part of the polymer chain.
- 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.
