Thermal degradation of esters/ethers derived from tartaric
The popularity of phthalates is due to their low price, excellent efficiency as plasticizers and compatibility with PVC, which consumes 80 % of global plasticizer production alone. The ideal plasticizer should be low in cost, display good compatibility with the polymeric substrate and exhibit resistance to temperature change or chemical
Current Status of Plasticizer Research | SpringerLink
Currently, the production of environmentally friendly, non-toxic plasticizers is facing two major technical barriers: (1) diverse side products and low yield; and (2) low production volume and high cost [135, 136]. Products such as citrates are a new type of non-toxic, odorless green phthalate plasticizer substitute and have been widely used in
US6310235B1 - Method for producing ester plasticizers
Method for producing ester plasticizers Abstract The invention relates to an improved method for producing ester plasticizers by reacting di- or polycarboxylic acids or their...
A potentially general approach to aliphatic ester-derived PVC
The safety of flexible polyvinyl chloride (PVC) materials is now being questioned, partially due to allegations that di-(2-ethylhexyl) phthalate (DEHP), the dominant PVC plasticizer, is an endocrine disruptor and a probable carcinogen. As sustainable alternatives, aliphatic ester-derived plasticizers feature
Method for producing ester plasticizers - Justia
1. A process for preparing ester plasticizers by reacting dicarboxylic or polycarboxylic acids or their anhydrides with alcohols in the presence of a titanium-, zirconium- or tin-containing catalyst, which comprises allowing a mixture of acid or acid anhydride and alcohol to react first at from 100 to 160° C. while removing any water formed, completing the reaction by addition of the catalyst
- What are common ester plasticizers for ECO?
- Ester plasticizers are compatible with ECO where the plasticizer has a similar polarity to that of the polymer. DOP, DIDP, and TOTM are common choices. Most ester plasticizers cannot withstand the post-cure cycles and temperatures typically sued with FKM.
- How do I Choose an ester plasticizer?
- A610), can be found on pages 7-8.When selecting an ester plasticizer, it is important to consider which elastomer is being used and the properties of that elastomer. Plasticizers and elastomers need to be compatible with each other b
- Which ester plasticizers were tested?
- Six Hallstar ester plasticizers were mixed into a neoprene WK compound and evaluated to assess the plasticizer effects on the crystallization rate. The results show Paraplex® G-62 interferes with the cure system used in our standard neoprene WK recipe.
- Can a benzoate plasticizer be produced based on a fraction isolated from EDR?
- The purpose of the work was to study the possibility of producing a benzoate plasticizer based on a fraction isolated from EDR and enriched with 2,4-diethyl-1,3-octanediol.
- How is benzoate plasticizer prepared?
- Method of benzoate plasticizer preparation. A three-necked round-bottom flask equipped with a thermometer and a reflux condenser with a Dean–Stark attachment was charged with 310.10 g of the alcohol fraction and 97.70 g (0.8 mol) of benzoic acid.
- Which plasticizers are used in polyvinyl chloride compositions?
- In the industry, based on glycols, predominantly dibenzoate plasticizers (for example, the trade mark Benzoflex) are produced, which are utilized as secondary solvating plasticizers in polyvinyl chloride compositions.
