Iseti yeSampula yePlastiki

Iplastiki yikhompawundi yepolymer (macromolecules) efakwe ipolymerization ngokudibanisa okanye ukuphendula kwe-polycondensation nge-monomers njengezinto ezisetyenzisiweyo. Isakhono sayo sokuchasana noku deformation siphakathi. Iphakathi kwefayibha kunye nerabha. Iqulethwe nge-resin yokwenziwa kunye nokuzaliswa, iiplasticizers, kunye ne-stabilizers. Iqukethe izongezo ezinje ngeearhente, izinto zokuthambisa kunye nee-pigment.
Icandelo eliphambili leplastiki yintlaka. I-Resin ibhekisa kwikhompawundi engaxutywanga nezongezo ezahlukeneyo. I-term resin yayibizwa ngokuba yi-lipids egcinwe yizityalo kunye nezilwanyana, ezifana ne-rosin kunye ne-shellac. I-resin i-akhawunti malunga ne-40% ukuya kwi-100% yobunzima bebonke beplastiki. Iipropathi ezisisiseko zeeplastiki ikakhulu zimiselwe bubume bentlaka, kodwa izongezo zikwadlala indima ebalulekileyo. Ezinye iiplastiki zenziwe ngokukodwa ngee-resin zokwenziwa, kungekho okanye zongezwa kancinci, njengeplexiglass, polystyrene, njl.
