Plasticizers: Types, Uses, Classification, Selection & Regulation
Plasticizers are most widely used additives in plastics. They are generally available as non-volatile, colorless liquids. Plasticizers increase the flow and thermoplasticity of a polymer by decreasing the viscosity of the polymer melt.
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.
Plasticizer - an overview | ScienceDirect Topics
Plasticizers are general colorless liquids which are relatively nonvolatile. Most of the plasticizers used for carpets are esters of phthalic acids (phthalates) with a wide variety of long chain alcohols. Plasticizers are classified according to function or structure. The functional classifications are either primary or secondary.
Selecting Plasticizers for Adhesives and Sealants
Plasticizers are organic liquids or solids that are incorporated by melt processing or diffusion into a compatible polymer to reduce interaction between molecules and improve molecular mobility.
Plasticizers in Paint & Coatings: Uses, Types and Selection
DOP or DnOP is light-colored, low volatility & odorless liquid. It was the most commonly used all-purpose plasticizer, although mainly used for polyvinyl chloride (PVC) resins. It is insoluble in water & has a low viscosity of 56 mPa.s at 25°C. DOP features: Good stability to heat and ultraviolet light; Broad range of compatibility, and
- Are ionic liquids a good plasticizer for poly (methyl methacrylate)?
- Room temperature ionic liquids (ILs) based on imidazolium salts, were found to be excellent plasticizers for poly (methyl methacrylate), with improved thermal stability, and the ability to reduce glass transition temperatures to near 0 °C.
- 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.
- 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).
- Can plasticizers maintain lubricity under subzero conditions?
- Developing new plasticizers that maintain lubricity at temperatures under subzero conditions would provide new materials with reduced low temperature failure, and can be used in such areas as space exploration, and storage of liquefied gases.
- How to reduce leaching and migration of plasticizers from polymer surface?
- Leaching and migration of plasticizers from polymer surface can be reduced by coating the polymer surface with some non-migrating material. But these coatings are usually thick and may often cause a reduction in flexibility of the polymeric materials.
- Are ils better than traditional plasticizers?
- The experiments described above show the potential technical advantages of using ILs over traditional plasticizers: ability to control Tg over wide temperature ranges, ability to reduce volatility for high temperature applications, and elastic moduli that match those of DOP.
