Extruded cast

NatureWorks PLA can be extruded, cast or biaxially oriented, and thermoformed using conventional processing equipment. The company claims that NatureWorks PLA performs like traditional petroleum-based plastics, and in some cases offers better performance characteristics, including gloss, clarity, strength, and flavour and aroma barrier.

The simplest and most effective way to improve the properties is to combine soy protein with a biodegradable polymer to form soy based biopol mers. The other method is to use functional monomers or oligomers to modify the soy protein during the processing of soy protein with an extruder. Casting methods or pretreatment methods with soy protein to form articles for applications can be used. 

Silicone-polycarbonate co-polymer n. Introduced in 1969 by the General Electric Co., these thermoplastic co-polymers vary from strong elastomers to rigid engineering plastics, depending on composition. They can be extruded, cast, or molded into optically clear films.

Ethyl Cellulose n (1936) (EC) An ethyl ether of ceUulose formed by reacting ceUulose steeped in alkali with ethyl chloride it is a white granular thermoplastic resin. Since the repeating units are etheric, it is chemicaUy different from other ceUulosics, which are esters, and is therefore not compatible with them. EC resin can be injection molded, extruded, cast into film, or used as a coating material. It has the lowest density of aU ceUulosic plastics, good toughness and impact resistance, and is dimension-aUy stable over a wide temperature range. Syn Carbitol. 

When extruding cast billets, of which only the faces are machined, a shell forms in the container, the thickness of which is about 2 to 3 mm depending on the billet diameter. It containes oxides, dross and other casting impurities and eliminates the need for machining the billets. If this shell were to be pulled out of the container after the extrusion by means of the ram, a very high pullback power would be required. Therefore a loose dummy block, whose diameter is slightly larger than that... 

Applications include multilayer barrier films with PA6 (polyamide 6)/ethylene-vinyl alcohol (EVOH)/ PA6 for the highest barrier applications especially for medical products, co-extruded cast films based on PP or PE with fillers such as calcium carbonate monoaxially stretched to achieve breathability to provide a water barrier but enabling water vapour to permeate the film, used in domestic wrapping, roof underlay applications, hygiene products, for example, nappies and feminine care. 

Conductor accessories can be rolled, extruded, cast, or forged. Common forms of aluminum conductors are single wire and multiple wire (stranded, bunched, or rope layed). Each is used in overhead or other tensioned applications, as well as in nontensioned insulated applications.
