Long- and short-term stability of plasticized poly(lactic acid
There are many plasticizers investigated by the researchers in the literature, such as glyceryl lactate , hexadecyl lactate glucose esters , isosorbide dioctoate , epoxidized soybean oil [7, 8], epoxidized palm oil N-octyl lactate , citrate esters [11,12,13,14,15], epoxidized fatty acid esters , glycerol , oligomeric lactic acid [8, 12] for the plasticization of PLA.

Glycol Ethers Properties & Examples, Organic Solvents - Sigma-Aldrich
Glycol ethers are characterized by their excellent solvency, chemical stability and compatibility with water and a number of organic solvents. The dual functionality present in the CELLOSOLVE and CARBITOL solvents and the alkoxytriglycol glycol ethers accounts for their unique solvency properties.
Effect of glycerol plasticizer loading on the physical
This research was set out to explore the development of arrowroot starch (AS) films using glycerol (G) as plasticizer at the ratio of 15, 30, and 45% (w/w, starch basis) using solution casting
- 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.
- Are polyethylene glycols a good plasticizer?
- Polyethylene glycols (PEGs) with low molecular weight, such as PEG200 and PEG400, are considered environmentally friendly, safe, inexpensive, recyclable, and water-soluble plasticizers . They are widely employed due to their biodegradability, biocompatibility, and non-toxicity properties.
- How to improve internal plasticization of cellulose esters?
- High reaction temperatures, long reaction times, basic catalysts, or special acylation reagents are often employed to increase the efficiency of internal plasticization. Moreover, the thermo-mechanical properties of cellulose esters obtained in this way are seldom satisfactory and do not pay back the costs and efforts of their synthesis.
- Which polar plasticizer is suitable for cellulose acetate?
- A polar plasticizer with a proton-acceptor character, such as an ester, is useful in polymers with average polarities , e.g., cellulose acetate. Apart from the chemistry of the selected plasticizer, other factors influence compatibility.
- How to choose an ester plasticizer?
- The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties. The study of these properties by the rubber compounder will help in selecting an ester plasticizer. ASTM D883, "Plastics Nomenclature," American Society for Testing and Materials, Philadelphia, PA.
- Do fluorocarbon elastomers accept ester plasticizers?
- Fluorocarbon elastomers will accept a relatively wide range of ester plasticizers, but here, with both the high temperature post cure and application temperatures ranging to 232°C, they find use only at very low levels for processing. The selection of an ester plasticizer can often be confusing because of the large choice available.
