Extruded polystyrene material is also used in crafts and model building, in particular architectural models. Because of the extrusion manufacturing process, XPS does not require facers to maintain its thermal or physical property performance. Thus, it makes a more uniform substitute for corrugated cardboard. Thermal conductivity varies between ...
Unassembled parts of a Hasegawa 1/72 F/A-18E kit. The frame surrounding the various parts is called the injection moulding "runner" or "sprue" The first plastic models were injection molded in cellulose acetate (e.g. Frog Penguin and Varney Trains), but currently most plastic models are injection-molded in polystyrene, and the parts are bonded together, usually with a plastic solvent-based ...
Styrene is an organic compound with the chemical formula C 6 H 5 CH=CH 2. Its structure consists of a vinyl group as substituent on benzene. Styrene is a colorless, oily liquid, although aged samples can appear yellowish. The compound evaporates easily and has a sweet smell, although high concentrations have a less pleasant odor.
Occidental Réplicas (Portugal) - Brand of a plastic plant for home products, that started to build models that were used or in use by the Portuguese armed forces current and past, age of discovery ships naus caravelles etc, spitfire Fiat G-91 fighters and T-6 Texan, and so on, sold several sprues molds to Revell and Italeri for several kits.
The currently most-consumed engineering plastic is acrylonitrile butadiene styrene (ABS), used for e.g. car bumpers, dashboard trim and Lego bricks. Engineering plastics have gradually replaced traditional engineering materials such as metal, glass or ceramics in many applications. Besides equalling or surpassing them in strength, weight, and ...
ASA can be made by either a reaction process of all three monomers (styrene, acrylonitrile, acrylic ester) or a graft process, although the graft process is the typical method. A grafted acrylic ester elastomer is introduced during the copolymerization of styrene and acrylonitrile. The elastomer is introduced as a powder. [11]
Aluminum Model Toys (AMT) is an American brand of scale model vehicles. The former manufacturing company was founded in Troy, Michigan, in 1948 by West Gallogly Sr. AMT became known for producing 1:25 scale plastic automobile dealer promotional model cars and friction motor models, and pioneered the annual 3-in-1 model kit buildable in stock, custom, or hot-rod versions.
A builder working on a model. Model building is a hobby and career [1] [2] that involves the creation of physical models either from kits or from materials and components acquired by the builder. The kits contain several pieces that need to be assembled in order to make a final model.
