Nanoparticle-Anchored Plasticizers - US EPA
TDA’s nanoparticles are designed to be inexpensive and attractive to the commodity polymer materials market. TDA scaled up production of nanoparticles from the gram to Pictured above is the device used to synthesize TDA’s nanoparticle-anchored plasticizers, which soften polyvinyl chloride (PVC), keep plastics soft longer, and do not escape.
Nanocomposite Anchored Plasticizers | Research Project
TDA's nanoparticles showed excellent compatibility with both the host resin as well as the processing methods. Plasticizers are designed to make the host material softer, decrease the tensile strength and modulus, and increase the elongation; TDA was able to affect these changes in rigid and flexible PVC.
Flexible and strong ternary blends of poly(vinyl chloride
These nanoparticles suppressed migration of plasticizers when the amount of nano-particles was less than 20 phr, the migration of the DINP and TOTM decreased 20 % . Show abstract Poly (vinyl chloride)(PVC), as the second general plastic just following the product of polyethylene (PE), has been widely applied in building, electrical parts
Final Report | Nanocomposite Anchored Plasticizers | Research
If properly designed, the plasticizing nanoparticles would show good dispersion without the loss in physical properties observed with larger particle fillers. TDA Research, Inc. (TDA) has shown that plasticizers anchored on nanoparticles can soften PVC, but cannot escape from the polymer.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Bio-based Plasticizers – They are based on epoxidized soybean oil (ESBO), epoxidized linseed oil (ELO), castor oil, palm oil, other vegetable oils, starches, sugars etc. Others – Includes Phosphates, Chlorinated Paraffins, Alkyl Sulfonic Acid Esters and more When added to polymer, these plasticizers provide several benefits as listed below.
- Can nanoparticles improve the mechanical properties of bioplastics?
- As explained, if starch-based bioplastics still have weak mechanical properties, it is necessary to provide fiber as reinforcement and several studies have shown that with the presence of nanoparticles, the resulting bioplastic mechanical properties are much better.
- What are natural based plasticizers?
- Nowadays, there is increasing interest in the use of natural-based plasticizers that are characterized by low toxicity and low migration. This group includes epoxidized triglyceride vegetable oils from soybean oil, linseed oil, castor-oil, sunflower oil, and fatty acid esters (FAEs) .
- What are biodegradable plasticizers?
- Biodegradable plasticizers such as soybean oil (SO), epoxidized soybean oil (ESO), dibutyl phthalate (DBP) and triethyl citrate (TEC) were added to poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) films, enhancing their thermal and mechanical properties. TEC or DBP presented better plasticizing effects than SO and ESO for PHBV .
- What types of plasticizers are used in hydrophilic polymers?
- In addition to water, the most commonly used plasticizers are polyols, mono-, di- and oligosaccharides. Polyols have been found to be particularly effective for use in plasticized hydrophilic polymers .
- What are plasticizers & how do they work?
- Plasticizers are low-molecular-weight compounds that are added to the polymer matrix to improve the film flexibility and workability. There is a wide range of plasticizers, (4,5,16,18−31) but their effectiveness will depend on the type of polymer network, which in our case will be nanocellulose.
- Which plasticizer is best for gelatin films?
- In terms of functional properties, GLY presented higher plasticizing effect and efficiency. Other plasticizers such as sucrose, oleic acid, citric acid, tartaric acid, malic acid, PEG, sorbitol, mannitol, EG, DEG, TEG, EA, diethanolamine (DEA) and TEA were also applied for gelatin films, modifying their mechanical and barrier properties.
