Polylactic acid can be processed like most thermoplastics into fiber (for example, using conventional melt spinning processes) and film. PLA has similar mechanical properties to PETE polymer, but has a significantly lower maximum continuous use temperature.
The glass-transition temperature T g of a material characterizes the range of temperatures over which this ... Polylactic acid (PLA) 60–65 140–149 Polyethylene ...
PLGA undergoes hydrolysis in the body to produce the original monomers: lactic acid and glycolic acid. These two monomers under normal physiological conditions, are by-products of various metabolic pathways in the body. Lactic acid is metabolized in the tricarboxylic acid cycle and eliminated via carbon dioxide and water.
Besides epoxy resins based on diglycidyl ether of bisphenol A, other polymer networks have been used to produce vitrimers, such as aromatic polyesters, [4] [5] polylactic acid (polylactide), [2] polyhydroxyurethanes, [3] epoxidized soybean oil with citric acid, [6] and polybutadiene. [7]
Polycondensation of glycolic acid is the simplest process available to prepare PGA, but it is not the most efficient because it yields a low molecular weight product. Briefly, the procedure is as follows: glycolic acid is heated at atmospheric pressure and a temperature of about 175 to 185 °C is maintained until water ceases to distill ...
Polylactic acid (polylactide) is a compostable thermoplastic aliphatic polyester derived from renewable resources, such as corn starch (in the United States), sugar beet pulp (in Europe), tapioca roots, chips or starch (mostly in Asia), or sugarcane. It is the most common material used for 3D printing with fused deposition modeling (FDM ...
Ingeo is a range of polylactic acid (PLA) biopolymers owned by NatureWorks. [1] Resinex Group distributes Ingeo in Europe. [2] Ingeo is created using carbon stored in plants via photosynthesis and takes the form of dextrose sugar. These sugars are then converted into a biopolymer through the processes of fermentation and separation.
There are also weaker dependencies on temperature, pressure/stress, etc., ... Polylactic acid: 1.46 [26] Pyrex (a borosilicate glass) 1.470 [27] Vegetable oil: 1.47 [28]
