Thermoplastics are a class of polymers that become soft and moldable upon heating and harden upon cooling. This process is reversible and can be repeated multiple times. They offer excellent processing capabilities and can be easily shaped using methods like injection molding and extrusion.

Izindlela ezivamile ze-thermoplastics zifaka phakathi i-Polyethylene (PE), i-Polypropylene (PP), i-Polyvinyl Chloride (PVC), i-Polystyrene (PS), kanye ne-Polycarbonate (PC).

Polyethylene i-polymer eyakhiwe kwi-ethylene monomers. Njengoba i-plastiki eyakhiqizwa kakhulu emhlabeni, inezinzuzo ezinhle zokuzinza kwezemvelo, ubukhulu obuphansi, ukujula okuphezulu, nokumelana okuqinile nokugqwala kwezemvelo. Izicelo zayo zifaka imikhakha eminingi kufaka phakathi ukupakisha, ukwakha, ezolimo, kanye nezimoto.

Ibhakede zepulasitiki, ifilimu elibambekayo, amafilimu okupakisha, kanye nezikhwama.

Polypropylene i-polymer eyodwa ebalulekile ye-thermoplastic resin eyenziwe nge-propylene monomers. Le resin engalapheki, engenamoya, emhlophe, futhi enokwakheka okuphezulu, ingenye yezinto ezilula kakhulu ze-plastics ezitholakalayo. Iyaqashelwa ngokwakhiwa kwayo okuqinile, ukumelana nokushisa, kanye nokuzinza kwekemikhali, ithola ukusetshenziswa ekupakisheni, ezimoto, ekwakheni, kwezobuchwepheshe, nasezempilweni.

Izikhwama ezihlanganisiwe, amafilimu, nezitsha zokudla.

Polyvinyl Chloride i-polymer ekhiqizwa kumonoma we-vinyl chloride. Le msebenzi engalapheki, engenamoya inikeza ukumelana okuhle nokugqwala kwemichiza, ukuvikelwa kukagesi, kanye namandla omshini. Isetshenziswa kabanzi ezakhiweni, ukupakisha, ezempilo, nasezimotweni.

PVC films, bags, IV bags, infusion tubes, and medical catheters.

Polystyrene i-colourless, i-transparent thermoplastic eyenziwe nge-free-radical polymerization ye-styrene monomers. Iphawuleka ngokuba ne-high transparency, i-good electrical insulation, i-ease of processing, kanye ne-chemical resistance. Isetshenziswa kakhulu ekupakisheni kokudla, emathoyizi, nasezinkomishini ezisetshenziswayo.

Polycarbonate iyinhlaka eqinile ye-thermoplastic polymer equkethe amaqembu e-carbonate (-O-C(=O)-O-) emgqeni wayo wemolekyuli, ivamise ukuhlanganiswa kusetshenziswa i-bisphenol A ne-phosgene (COCl₂). Iphakanyiswa kakhulu ngokucacile kwayo okuphezulu, amandla akhethekile, nokumelana okuhle kakhulu nokuphazamiseka, okwenza ifanele izinhlelo ezinzima.
