thermoplastic plastics (recyclable)
thermosetting plastics (non-recyclable)
thermoplastic and hypoplastic
In 1957 by two engineers, Alfred Fielding and Marc Chavannes
Step one: Get a large sheet of plastic over a layer of metal with holes in it. Step two: Let the metal with holes suck on the plastic making the holes. step three: Put a hot layer of plastic over it smelting it together. tada!!!
There are two ways; 1) Plastics can be metalized on the surface by the process of vacuum metalizing, in which metal filaments are vaporized on to the plastic surface and the condensed in a vacuum chamber. 2) Sputtering, the metal is ionized in a vacuum chamber by an electrical discharge between two electrodes, a metallic cloud forms inside the chamber and fogs the plastic parts with a thin layer of metal .
Plastic is primarily made from two types of materials: synthetic polymers and natural polymers. Synthetic polymers, such as polyethylene and polypropylene, are derived from petrochemicals through processes like polymerization. Natural polymers, such as cellulose and starch, can also be used to create biodegradable plastics. These materials can be combined or modified to produce a wide range of plastic products with varying properties.
They are thermosetting plastic and thermoplastic!
biodegradable and non-biodegradeable
