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.
Selection of Plasticizers for Coating Formulations
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)
Long- and short-term stability of plasticized poly(lactic acid
The aim of this study is to investigate the property stability of plasticized PLA for a time period of 2 years starting from the production. We have used three grades of PEG with different molecular weights such as 400, 8000, and 35,000 g/mol, namely PEG-400, PEG-8000, and PEG-35,000 in various concentrations such as 0, 5, 10, 15, and 20 wt%.
Selection of Light Stabilizers for Polymers
Aromatic TPU based on isocyanates like MDI are workhorse products and can be used in applications that require flexibility, strength and toughness. There are also applications which require good light stability such as shoe soles for example. The poor light stability of aromatic TPU requires the use of robust light stabilizers packages.
Plasticisers - Information Center
Ortho-phthalates, due to their high degree of compatibility with PVC, are the most widely consumed plasticisers. As can be seen from these figures, major plasticisers are high volume commodity chemicals, which take decades and billions of Euros to achieve full commercial development.
- What plasticizer combination yields the highest seal strength?
- The highest seal strength was obtained with a combination of sorbitol and glycerol. The same authors showed that sorbitol-plasticized films exhibited significantly better heat sealability than did the glycerol type.
- Can Esbo be used as a primary plasticizer for PVC plastisols?
- ESBO is usually mixed with co-plasticizers, which could be a reasonable practice used by industry in order to fulfil the specific migration limits of each plasticizer. However, since ESBO was seen to play a role in thermal stability of PVC it could be a good alternative as a primary plasticizer and/or stabilizer for PVC plastisols.
- What plasticizer type improves sago starch film heat sealability?
- Abdorreza et al.117 showed that the type and concentration of plasticizers govern the heat sealability as well as the seal strength of sago starch based films. The same authors showed that sorbitol-plasticized films exhibited significantly better heat sealability than did the glycerol type.
- Do plasticizers affect the stability of shellac?
- From our previous study, different types and concentrations ofplasticizers had some influenceson the stability of shellac. A significant increase in insoluble solids was obtained for plasticized shellacs with DEP and TA but the addition of PEG 400 gave the highest stability.
- 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 are the new plasticizers?
- These new forms of plasticizers offer new dimensions of plasticizer selection that provide additional functionality, such as electric conductivity by ionic liquids, to bio-based plastics. Some of these new plasticizers also provide high safety for use even in edible food packaging applications.
