Plastic compounding scheme. Compounding consists of preparing plastic formulations by mixing and/or blending polymers and additives in a molten state to achieve the desired characteristics. [1] These blends are automatically dosed with fixed setpoints usually through feeders/hoppers.
Polymer chemistry is a sub-discipline of chemistry that focuses on the structures, chemical synthesis, and chemical and physical properties of polymers and macromolecules. The principles and methods used within polymer chemistry are also applicable through a wide range of other chemistry sub-disciplines like organic chemistry , analytical ...
Polymer engineering is generally an engineering field that designs, analyses, and modifies polymer materials. Polymer engineering covers aspects of the petrochemical industry, polymerization, structure and characterization of polymers, properties of polymers, compounding and processing of polymers and description of major polymers, structure property relations and applications.
The additives in a masterbatch are chosen to impart desired physical property changes to a final plastic product. They can increase volumetric output due to thermal conductivity and volumetric expansion at a given temperature as well as potentially increasing the toughness, flexural stiffness, adhesion, and printability of a final product.

ASA is compatible with some other plastics, namely polyvinyl chloride and polycarbonate. ASA-PVC compounds are in use. [4] ASA can be processed by extrusion and coextrusion, thermoforming, injection molding, extrusion blow molding, and structural foam molding. [4] ASA is mildly hygroscopic; drying may be necessary before processing. [4]
In materials science, a polymer blend, or polymer mixture, is a member of a class of materials analogous to metal alloys, in which at least two polymers are blended together to create a new material with different physical properties. [1]
Solvent bonding differs from other plastic welding processes in that heating energy is generated by the chemical reaction between the solvent and thermoplastic, and cooling occurs during evaporation of the solvent. [5] Solvent bonding can be performed using a liquid or gaseous solvent.
