Plasticizers: Types, Uses, Classification, Selection & Regulation
Phthalate plasticizers are widely used in vinyl based building materials like floorings and wall coverings to provide them with flexibility and durability. Phthalate Plasticizer Regulations 2001-2006 - DINP and DIDP Are Safe for Use in Current Applications – ECPI Report
WO2017204913A3 - Purified plasticizers, production and use
The purified aromatic esters can be produced by esterifying carboxylic acid with methyl or ethyl alcohol, separating the resulting methyl or ethyl esters from the carboxylic acid and any byproduct impurities, and then transesterifying the methyl or ethyl esters with C 4 to C 14 alcohol to produce the purified aromatic esters.
Plasticizers production | Polynt Group
Around 90% of all Plasticizers are used in the production of flexible PVC. Minor applications include rubber, adhesives, sealants, paints, lacquers and lubricants. In order to obtain a soft PVC the Plasticizers must have the following essential performance properties: Resistance to extraction by oils, fats, hydrocarbons, aqueous solutions.
Plasticizer - an overview | ScienceDirect Topics
Plasticizers are used to convert PVC, a rigid plastic, into a soft, flexible, and elastic material. A plasticizer that is compatible with PVC and exhibits low volatility, good permanence, and high efficiency is referred to as a primary plasticizer. A secondary plasticizer has the opposite characteristics of a primary plasticizer.
US Patent for Purified plasticizers, production and use
Purified plasticizers, production and use Apr 11, 2017 - ExxonMobil Chemical Patents Inc. This disclosure relates to methods for producing purified aromatic esters useful as plasticizers, to the purified aromatic esters, and to polymer compositions containing the purified esters.
- Which plasticizer has the best mechanical properties?
- Of the plasticizers we synthesized, the best film mechanical properties were provided by OC plasticizer, containing primarily propylene glycol monoacetate, but also propylene glycol diacetate, acetic acid and propylene glycol in its mixture.
- Which plasticizer is most stable after 10 d?
- After 10 d, the migration trend of all samples had been stabled, it showed that the traditional plasticizer like DOP, DOTP and DOA had basically move out from the PVC matrix in non-polar environment due to their own single structure, while the PVC plasticized with A-ODL showed the best stability in all the environment.
- Why are plasticizers important in biopolymer-based films & coatings production?
- In biopolymer-based films and coatings production, plasticizers are also essential additives since they can improve flexibility and handling of films, maintain integrity and avoid pores and cracks in the polymeric matrix .
- Which plasticizer is used to make polyvinyl chloride (PVC) films?
- Subsequently, ricinoleate plasticizer, commercially available dioctyl phthalate (DOP), and bis (2-ethylhexyl) adipate (DOA) were added to prepare polyvinyl chloride (PVC) films for performance comparison.
- Are plasticizers a good choice for PVC?
- According to the statistics, the total output of PVC in the world was over 49.0 million tons in 2019 . However, as a rigid polymer, pure PVC have certain drawbacks without any additives . Therefore, plasticizers are generally blended to improve the mechanical properties and thermal stability of PVC materials , .
- Which plasticizer is best for chitosan?
- Glycerol and polyethylene glycol were found to be more suitable as plasticizers of chitosan than ethylene and propylene glycol. In addition, chitosan films containing 20 wt% glycerol or polyethylene glycol showed good stability for 5 months.
