Plasticizers: Types, Uses, Classification, Selection & Regulation
Most commonly used phthalate plasticizers include: DEHP: Low molecular weight ortho-phthalate. Still the world’s most widely used PVC plasticizer DINP, DIDP: High molecular weight ortho-phthalates Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates.
Combining Renewable Eleostearic Acid and Eugenol
The recent studies on sustainable plasticizer mainly focus on raw material source, synthesis method and plasticization, but the effect of chemical functional groups (epoxy group and ester group) of sustainable plasticizer on compatibility and thermal stability of plasticized polyvinyl chlorid (PVC) materials has been ignored. In this study, two kinds of sustainable plasticizers (eleostearic
Research progress of novel bio-based plasticizers and their
Abstract Plasticized polyvinyl chloride (PVC) has been widely used in the world. Petroleum-based plasticizers especially phthalates have been the most common plasticizers used in PVC. However, the global petroleum resources are becoming scarce gradually, and the hygienic requirements for plasticizers are increasing. Owing to the negative impact of petroleum-based plasticizers on human health
Plasticizers in Paint & Coatings: Uses, Types and Selection
Good stability to heat and ultraviolet light Broad range of compatibility, and Excellent resistance to hydrolysis Di-iso-octyl phthalate (DIOP) DIOP is like DOP, an all-purpose plasticizer for polyvinyl chloride, polyvinyl acetate, rubbers, cellulose plastics, and polyurethane. Di-iso-nonyl phthalate (DINP) & Di-iso-decyl phthalate (DIDP)
Plasticizer
Some common phthalate plasticizers are: Low Molecular Weight Ortho Phthalates Dimethyl phthalate (DMP), used in fragrances, as an insect repellent, and in several industrial processes as a solvent/carrier Diethyl phthalate (DEP), used in fragrances as a carrier and extender/fixative Diisobutyl phthalate (DIBP)
- Which plasticizers are used in flexible PVC products?
- More than 80% of plasticizers have been applied to flexible PVC products with the rest being polyvinyl acetate, vinyl chloride - vinyl acetate copolymer, cellulose acetate, and cellulose nitrate. Although the study history of plasticizing mechanism has been over 40 years, but so far there is still no systematic theory.
- What are plasticizers for polymers?
- 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.
- How are plasticizers classified?
- Plasticizers are classified according to their molecular structure into monomeric or polymeric types. The choice of the plasticizer is dependent on the requirements that have to be met for the final product and the conditions around that product’s use.
- What are plasticizers used for?
- Plasticizers are also often added to concrete formulations to make them more workable and fluid for pouring, thus allowing the water contents to be reduced. Similarly, they are often added to clays, stucco, solid rocket fuel, and other pastes prior to molding and forming. For these applications, plasticizers largely overlap with dispersants.
- 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 is a bio-based plasticizer?
- Bio-based plasticizers have been investigated, such as glycerol triacetate (Triacetin) and acetyltributylcitrate. They are used in niche applications. Epoxidized soybean oil is used broadly as a secondary plasticizer in many vinyl applications. Note: Bisphenol A, or BPA, is not a plasticizer, although it is often wrongly described as one.
