Mea masani palasitika:
O le palasitika e masani ona faʻaaogaina e le o se vaega e tasi, e faʻapipiʻiina mai le tele o mea.Faatasi ai ma i latou, o polymers mole maualuga (poʻo resins synthetic) o vaega autu ia o palasitika.E le gata i lea, ina ia faʻaleleia atili le faʻatinoga o palasitika, e tatau ona faʻaopoopoina mea faʻapitoa fesoasoani, e pei o faʻatumu, palasitika, lubricants, ma faʻamautu, e tatau ona faʻaopoopoina i le maualuga o le mole mole., Colorants, antistatic agents, ma isi, e mafai ona avea ma palasitika ma faʻatinoga lelei.
O mea faʻapipiʻi palasitika, e taʻua foi o mea faʻapipiʻi palasitika, o mea faʻapipiʻi e tatau ona faʻaopoopo e faʻaleleia ai le gaioiga o le gaosiga o le polymer (synthetic resin) poʻo le faʻaleleia o le faʻatinoga o le resini lava ia pe a faʻaogaina le polymer (synthetic resin).Mo se faʻataʻitaʻiga, ina ia faʻaitiitia le vevela o le polyvinyl chloride resin, faʻapipiʻi le plasticizer e faʻamalulu ai le oloa;o le isi faʻataʻitaʻiga o le faʻaopoopoina o se mea faʻafefete mo le saunia o le mama mama, faʻafefete, faʻafefe vevela, ma faʻafefe leo;O le vevela o le pala e latalata tele i le vevela o le gaosiga, ma e le mafai ona ausia e aunoa ma le faʻapipiʻiina o le vevela.O le mea lea, o mea faʻapipiʻi palasitika o loʻo i ai se tulaga taua tele i le gaosiga o palasitika.
Palasitika o polymer compounds (macromolecules), e masani ona taʻua o palasitika po o resins, lea e polymerized e monomers e pei o mea mata e ala i le faaopoopo polymerization po polycondensation tali.O le tuufaatasiga ma foliga e mafai ona suia saoloto.O lo'o faia i resini fa'asusu ma fa'atumu.Plasticizer, stabilizer, lubricant, pigmenti ma isi mea faaopoopo.
