An example is polylactic acid based on glucose form starch.
Polylactic acid is a bioplastic but not a biopolymer.
The magic ingredient in this plastic is polylactic acid, a corn-based polymer.
It is sometimes used as a polymerization initiator, such as for the production of polylactic acid.
A prominent example is poly-3-hydroxybutyrate, the renewably derived polylactic acid, and the synthetic polycaprolactone.
Ecovio consists of Ecoflex and a high content of polylactic acid.
Cargill has figured out how to make polylactic acid for as little as $3 a pound in Savage.
A commonly used synthetic material is PLA - polylactic acid.
Polylactic acid can be recycled to monomer by thermal depolymerization or hydrolysis.
Examples of biopolyesters includes polyhydroxybutyrate and polylactic acid.
The team was the first in the world to successfully apply this particular blending strategy to polylactic acid and thermoplastic starch.
Case in point: A group of Hewlett's scientists developed a prototype printer with a polylactic acid shell.
Polylactic acid can be processed like most thermoplastics into fiber (for example, using conventional melt spinning processes) and film.
Polylactic acid (used in making decomposable plastic cups)
Abbott laboratories has used a dissolvable material, polylactic acid, that will completely absorb within 2 years of being implanted.
Non-permanent products include Polylactic acid and hyaluronic acid.
There are reports of using polyglycolic acid and polylactic acid to engineer vascular tissue for heart repair.
The research will help in identifying unsafe performance characteristics and failure modes of medical devices̓ materials, such as polyurethane and polylactic acids.
They are UV stable, in contrast to other bioplastics from polymers such as polylactic acid, partial ca.
The bags, made of a renewable vegetable-based material and corn-based polymer polylactic acid, take only 14 weeks to decompose.
One of the most commonly used polymers for packaging purposes is polylactic acid, PLA.
Polylactic acid (PLA) is a transparent plastic produced from corn or dextrose.
Jeff tells the story of his experiences of being treated with polylactic acid (New-Fill)
The company's D(-) lactic acid started production at commercial scale in June 2008 for use in polylactic acid.
The material used to make these kinds of disposable foodservice products is primarily PLA or polylactic acid.
Cargill-Dow polymers are already in production with a polylactide derived from corn.
Ingeo is a polylactide fibre blended with other fibres such as cotton and used in clothing.
This material is produced from plastic that consists of polylactide, a corn-based versatile polymer.
Previously, thermoplastic starch and polylactide were known to be like oil and water – an immiscible blend.
For example, lactic acid can be used to make polylactide, a versatile cost-effective and green substitute for petrochemical-based plastics.
The new Absorb device is made from a natural material known as a polylactide, which is commonly used in medical implants such as dissolvable stitches.
The company's plant, in Blair, Neb., uses corn sugar to produce polylactide plastic packaging materials and its Ingeo-brand fibers.
In particular it is especially interesting for the preparation of long term implantable devices, owing to its degradation which is even slower than that of polylactide.
In the presence of catalysts lactide polymerize to either atactic or syndiotactic polylactide (PLA), which are biodegradable polyesters.
Lactide can be polymerized to polylactic acid (polylactide) using suitable catalysts, with either syndiotactic or a heterotactic stereocontrol, to give materials with many useful properties:
A variety of catalysts can polymerise lactide to either heterotactic or syndiotactic polylactide, which as biodegradable polyesters with valuable (inter alia) medical properties are currently attracting much attention.
Some coatings which accomplish this include chlorhexidine incorporated hydroxyapatite coatings, chlorhexidine-containing polylactide coatings on an anodized surface, and polymer and calcium phosphate coatings with chlorhexidine.
In a related study, a more than 700-fold decrease in oxygen permeability of a polylactide (PLA) film when a nanocellulose layer was added to the PLA surface was reported.
Polymer networks other than epoxy resins based on diglycidyl ether of bisphenol A have been utilized in vitrimer technology, such as polylactide, polyhydroxyurethanes, epoxidized soybean oil with citric acid, and polybutadiene.
Due to the chiral nature of lactic acid, several distinct forms of polylactide exist: poly--lactide (PLLA) is the product resulting from polymerization of ,-lactide (also known as -lactide).
Organic threads (such as polylactide filament for example) are stitched through laminate layers of fiber reinforced polymer, which are then boiled and vacuumed out of the material after curing of the polymer, leaving behind empty channels than can be filled with healing agents.
