Plasticizers – Benefits, Trends, Health, and Environmental
Around 90 % of all plasticizers are used in the production of flexible polyvinyl chloride (PVC), also known as vinyl. The main applications for flexible PVC include flooring and wall coverings, roofing membranes, electrical cable and wire insulation, automotive applications, medical devices, synthetic leather goods, and so forth.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Plasticization Methods & Processing with Plasticizers There are two main principal methods exist for plasticization - Internal Plasticization and External Plasticization. Internal Plasticization A polymer can be internally plasticized by chemically modifying the polymer or monomer so that the flexibility is increased.
Plasticizer
For example, plasticizers are commonly added to polyvinyl chloride (PVC), which otherwise is hard and brittle, to make it soft and pliable; which makes it suitable for products such as shower curtains, vinyl flooring, clothing, bags, flexible plastic tubing, and electric wire insulation/coating.
Eastman Plasticizers for Adhesives
Admex 6995 is a medium molecular weight, light colored, polymeric adipate with a mild ester odor. Benzoflex 9-88 is a high solvating benzoate ester plasticizer that can be used in a wide variety of polymer systems and applications. Its diverse uses include resilient flooring, adhesives, caulks, and sealants.
Plasticizers Derived from Biomass Resources: A Short Review
These bio-based plasticizers mainly include epoxidized plasticizer, polyester plasticizer, macromolecular plasticizer, flame retardant plasticizer, citric acid ester plasticizer, glyceryl ester plasticizer and internal plasticizer.
- Are plasticizers effective as processing aids for HME process?
- The physical and mechanical properties of plasticizers, in selected binary (polymer:plasticizer) and ternary (active pharmaceutical ingredient:polymer:plasticizer) systems, were evaluated to assess their effectiveness as processing aids for HME process.
- How do you calculate plasticization efficiency?
- Primarily, plasticization efficiency is a first-order process and can be expressed as A = A 0 e − K [c] plasticizer where A = measured parameter, A 0 = A when plasticizer concentration is 0, K = rate constant, and [c] plasticizer = plasticizer concentration.
- Do Plasticizers improve formulation performance and stability?
- Although these plasticizers are effective as processing aid for HME, the effect of these plasticizers on formulation performance and stability is of utmost interest for the development of stabilized amorphous formulations.

- Which plasticizers are used in continuous manufacturing of RTV SD formulations?
- Finally, Span 20 and HSPC were shown to be the most efficacious plasticizers, and the SD formulations with PVPVA 64 and Span 20 or HSPC (1:4.5:0.5 (w/w)) were used in manufacturing of RTV SD formulations via HME at different extrusion temperatures according to the T g value of the mixtures (Table S2). 3.3. Continuous manufacturing by HME
- How to select solid-state plasticizer?
- The selection of solid-state plasticizer should include miscibility of plasticizer in polymer as well as API and its effect on T g and η 0 of the final system. It can be summarized that when components are miscible, different techniques will lead to the consistent plasticization effect prediction.
- Do plasticizers affect HME process and product performance?
- Although various studies have demonstrated the effect of plasticizers on HME process and product performance, 21, 22, 23, 24, 25 no single study has investigated the systematic approach for selecting a suitable plasticizer.
