Plasticizers: Types, Uses, Classification, Selection & Regulation
Phthalate Plasticizers Benefits & Limitations Phthalate Plasticizers Applications Cost: Phthalates which have been used as PVC plasticizers since the earliest days of flexible PVC are both inexpensive and effective. The collapse of oil prices which began in 2015 has further reduced the price of petrochemicals, including phthalate esters.
Long- and short-term stability of plasticized poly(lactic acid
Compounding PLA with higher molecular weight plasticizers gave similar thermal behaviors as compared to PEG-400 and PEG-POSS systems. It was found that the effect of molecular weight of PEG-based plasticizers did not make any significant effect by the time in short term, i.e., 1 day.
Di(2-propylheptyl) phthalate: A new plasticizer
Plasticizers: health aspects. January 1998. About 1 million tons of plasticizers are used annually in Western Europe, mainly in the plasticization of PVC. The vast majority of plasticizers (around
Plasticizer - an overview | ScienceDirect Topics
Good plasticization involves interspersing plasticizer molecules between PVC chains, breaking the small amount of native PVC crystallinity, and internally lubricating the polymer blend. While there is no formal chemical bond between plasticizer and polymer, the polar attraction between them makes plasticized PVC more than a simple physical mixture.
Plasticizer
Sebacate - based plasticizers provide excellent compatibility with a range of plastic materials and synthetic rubbers (specifically nitrile rubber and neoprene), superior properties at low temperatures, and good oil resistivity. Some examples are: Dibutyl sebacate (DBS) Di- (2-ethylhexyl)sebacate, Di-octyl Sebacate [15] (or DOS plasticizer)
- 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.
- What is a good alternative to phthalates in Plasticized PVC?
- The use of natural products, in particular those obtained from vegetable oils and fats, can be considered an adequate and environmentally friendly alternative to phthalates in plasticized PVC . Epoxidized soybean oil (ESBO) is a vegetable oil widely used as plasticizer and/or stabilizer for PVC in food contact materials , , , , .
- 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.
- How to choose a plasticizer?
- 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. This may include low volatility, high permanence, low temperature flexibility, flame retardancy, high thermal stability and saponification resistance.
- Does excess plasticizer affect the initial degradation temperature of plastisol?
- The excess of plasticizer in the plastisol with 50 wt% of ESBO could be confirmed in Fig. 5 since the two characteristic endothermic peaks were clearly distinguished. As indicated, this excess in the plasticizer concentration affected the high initial degradation temperature obtained by TGA for this sample.
- 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.
