Thermosoftening and thermosetting plastics. Plastics can be put into one of two categories, depending on how they respond when heated. Thermosoftening Plastics are polymers. A polymer is a substance made of many repeating units. The word polymer comes from two Greek words: poly, meaning many, and meros In practice, those problems are often reduced by steel surface coatings, which prevent any contact between steel and polymer melt [2], [3].

2 While it is hard to define plastic film, it is even more difficult to quantify how much of it is used in packag-ing and nonpackaging applications. That is primarily because of the way that data are reported. For exam-ple, trade organizations and major publications rarely

There are 3 principal classes of polymers – thermoplastics, thermosets, and elastomers. In thermosetting plastics the long chain molecules exist in an amorphous network with cross-linked bonding.

On the other hand, we can define plastic as a semi-organic material derived from oil or petroleum. Minimization of Wear of Polymers by Plasma Treatment • Crystalline polymers: HDPE, POM • Amorphous polymers: PMMA, PC • CASING (Cross-linking by activated species of inert gases) • Helium plasma (1 torr, 13.56 MHz, 100 Watts, Room temp.) for 500 and 1000 seconds • Pin-on-disk, Normal load = 4.4 N, speed = 3.3 cm/s 2019-06-27 · Among the earliest were semi-synthetic polymers, which are natural polymers modified in some way. By 1820, natural rubber was modified by making it more fluid; and cellulose nitrate prepared in 1846 was used first as an explosive and then as a hard moldable material used in collars, Thomas Edison's film for movies and Hilaire de Chardonnet's artificial silk (called nitrocellulose).
