Plant-Based Protein Films and Coatings | SpringerLink
From a perspective of practical and cost implication, plasticizer/protein on a mass basis is most commonly used when comparing the efficacy of the protein film plasticizers. For plasticizers with similar molecular structures (e.g., PEGs), on a mass basis of plasticizer to protein, plasticizers with lower molecular weight tend to be more efficient in plasticizing the protein films than the
Mesamoll | The universal plasticizer | LANXESS
Some plasticizers develop a high potential regarding scope of use, but they are designed for a specific use. Unimoll AGF, our largely bio based plasticizer, was developed for the use in articles intended to come into contact with foodstuffs. Our Uniplex Benzoates are mainly solid special plasticizers used in hot-melt adhesive & equipment
Progress in bio-based plastics and plasticizing modifications
Some of the most commonly known bio-based plastics in today's marketplace in terms of production and renewability are poly (lactic acid) (PLA), polyhydroxyalkanoates (PHAs), starch plastics, cellulose esters and protein based plastics ( Fig. 1 ).
Extrusion Processing and Properties of Protein‐Based Thermoplastics
A protein-based material could be defined as a three-dimensional macromolecular network, stabilized and strengthened by hydrogen bonds, hydrophobic interactions, and disulfide bonds. 10 Globular proteins are required to unfold and realign before a new three-dimensional network can be formed, and stabilized by new inter- and intra-molecular interactions. 7, 11-13 Protein-based bioplastics are
Plasticizers: POLYSORB ID, plant-based solutions
POLYSORB ID - isosorbide diester. POLYSORB ID can be used to make diesters obtained from esterification of isosorbide with plant-based fatty acids. It offers outstanding compatibility and processability with PVC resins. Due to its great efficiency, it can be considered as an alternative of choice to standard petrochemical-based plasticizers.
- 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 types of plasticizers are used in protein films?
- Common external plasticizers used in protein films are typically polyols, mono-, di-, and oligosaccharides, as well as fatty acids and phenolic acids . The selection of a plasticizer for a particular polymeric system depends on their compatibility with each other and the desired characteristics of the final product .
- How do Plasticizers improve protein-based films?
- They increase the free volume between chains, introduce more mobility to the polymer, and act as internal lubricants by reducing frictional forces between polymer chains. Plasticizers lower the glass transition temperature [13, 65, 66]. The complexity of plasticization seems to be a major bottleneck for the improvement of protein-based films.
- Can biodegradable plasticizers increase the flexibility of protein-based materials?
- To increase the flexibility of protein-based materials, several researchers have reported the application of natural and/or biodegradable plasticizers, which reduce polymer chain-to-chain interactions by binding to the protein, distributing throughout the polymer matrix, and therefore increasing the free internal space.
- 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 is a plasticizer in chemistry?
- The council of the IUPAC (International Union of Pure and Applied Chemistry) defined a plasticizer as “a substance or material incorporated in a material (usually a plastic or elastomer) to increase its flexibility, workability, or distensibility”.
