Processes such as this may boost PLA’s presence in the plastics market, as improving the mechanical properties will be important to replace current petroleum-derived plastics. It has also been demonstrated that the addition of a PLA-based, cross-linked nucleating agent improved the degree of crystallinity of the final PLA material. [ 7 ]
The plastic nurdles are always white or clear. Pigments or other additives are added to the material before it is melted to create coloured filament or filament with special properties, e.g. increased strength or magnetic properties. Before the filament is extruded the nurdles are heated to 80 °C to dry it and reduce water content.
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 different immune responses that the body could have depending on where the polymer is placed. For example, in drug delivery systems (DDS), PLGA and PLA implants with high surface area and low volume of injection can increase one's chance of immune response as the polymers degrade in the body.
CAMPUS (acronym for Computer Aided Material Preselection by Uniform Standards) is a multilingual database for the properties of plastics. It is considered worldwide as a leader in regard to the level of standardization and therefore, ease of comparison, of plastics properties. It also supports diagrams to a large extent.
Honey Garlic Glazed Salmon. This savory-sweet salmon is quick and easy enough for weeknights (ready in under 30 minutes), but is also fancy enough for special occasions. If you’re a seafood ...

All of the plastic parts for the machine on the right were produced by the machine on the left. Adrian Bowyer (left) and Vik Olliver (right) are members of the RepRap project. RepRap (a contraction of replicating rapid prototyper ) is a project to develop low-cost 3D printers that can print most of their own components.
