Plasticizer
A plasticizer ( UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture. Plasticizers are commonly added to polymers such as plastics and rubber, either to facilitate the handling of the
Plasticizers: Types, Uses, Classification, Selection & Regulation
Still the world’s most widely used PVC plasticizer DINP, DIDP: High molecular weight ortho-phthalates Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates. They are made from aliphatic dibasic acids such as adipic acid and alcohols.
Application of Different Vegetable Oils as Processing Aids
Rubber composites based on renewable vegetable oils are being increasingly developed, as these materials significantly reduce the use of petroleum-based carcinogenic oils as plasticizers in rubber products. Apart from renewability, vegetable oils have some major advantages, such as easy availability, biodegradability, and environmentally friendly nature. Until now, vegetable oils, such as palm
Synthesis and properties of castor oil based plasticizers
Synthesis of acetylated castor oil (ACO) Castor oil (93.4 g) and acetic anhydride (27.5 g) were added to a 500 mL four-necked flask, and were stirred at 140 °C for 2 h. Then the reaction mixture was washed to pH = 7 with sodium carbonate solution and distilled water. Then the water was removed by vacuum distillation.
Epoxidized Jatropha Oil as a Sustainable Plasticizer to Poly
It was reported in the literature that an increase in thermal stability of epoxidized oil-plasticized PLA was due to their good interaction and plasticizer dispersion within the PLA matrix [3,9,19]. Furthermore, the homogeneously and well dispersed EJO could act as a protective layer, which deterred the release of volatile degradation products
- Are castor oil based polyol esters a good plasticizer?
- Migration stability and volatility stability of tests showed that with the increasing of the molecular weight of castor oil based polyol esters, the migration stability and volatility stability are enhanced. They could be with potential application used in food packing, children toys and medical devices as the main plasticizer.
- Can vegetable oil based plasticizers be used for plasticized poly (vinyl chloride) materials?
- The use of vegetable oil based plasticizers can create new application for plasticized poly (vinyl chloride) (PVC) materials. In this study, novel environmental castor oil based polyol esters (COPE-1, ECOPE-1, COPE-2 and ECOPE-2) were synthesized and characterized with FT-IR and 1 H NMR.
- Is castor oil based diglycidyl ester plasticizer good for PVC?
- A castor oil-based diglycidyl ester plasticizer (C26-DGE) was prepared by Chen et al.17 with ricinoleic acid as raw material and results showed that the plasticizer endowed the PVC matrix with enhanced compatibility and flexibility.
- 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.
- Can castor oil based polyol esters improve thermal stability of PVC blends?
- PVC materials were prepared via blending the synthesized castor oil based polyol esters as the main plasticizer. Properties of the PVC materials were investigated and compared to those of commercial plasticizers (DOP and ESO). The results showed that castor oil based polyol esters could significantly improve thermal stability of PVC blends.
- 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 , .
