Phofo ea putty e entsoe haholo-holo ka lintho tse etsang filimi (lisebelisoa tse kopanyang), li-filler, lintho tse bolokang metsi, li-thickeners, li-defoamers, jj. Lisebelisoa tse tloaelehileng tsa lik'hemik'hale tse tala tse fumanehang phofong ea putty li kenyelletsa haholo-holo: cellulose, starch e entsoeng esale pele, starch ether, polyvinyl alcohol, phofo ea latex e qhalakanngoang, jj. Ka tlase, Polycat e tla sekaseka ts'ebetso le ts'ebeliso ea lisebelisoa tse fapaneng tsa lik'hemik'hale bakeng sa hau ka bonngoe.
Faeba:
Faeba (US: Faeba; Senyesemane: Faeba) e bolela ntho e entsoeng ka likhoele tse sa khaotseng kapa tse sa khaotseng. Tse kang faeba ea limela, moriri oa liphoofolo, faeba ea silika, faeba ea maiketsetso, jj.
Selulose:
Cellulose ke polysaccharide e kholo e entsoeng ka glucose 'me ke karolo e ka sehloohong ea sebopeho sa mabota a sele ea limela. Mochesong oa kamore, cellulose ha e qhibilihe ka metsing kapa li-solvents tse tloaelehileng tsa organic. Sekhahla sa cellulose sa k'hothone se batla se le 100%, e leng se etsang hore e be mohloli o hloekileng ka ho fetisisa oa tlhaho oa cellulose. Ka kakaretso lehong, cellulose e etsa 40-50%, 'me ho na le 10-30% hemicellulose le 20-30% lignin.
Phapang pakeng tsa cellulose (ka ho le letona) le starch (ka ho le letšehali):
Ka kakaretso, starch le cellulose ke li-polysaccharide tse kholo, 'me foromo ea limolek'hule e ka hlalosoa e le (C6H10O5) n. Boima ba limolek'hule tsa cellulose bo boholo ho feta ba starch, 'me cellulose e ka bola ho hlahisa starch. Cellulose ke D-glucose le β-1,4 glycoside Li-polysaccharide tse kholo tse entsoeng ka litlamo, ha starch e etsoa ka litlamo tsa α-1,4 glycosidic. Cellulose hangata ha e na makala, empa starch e na le makala ka litlamo tsa glycosidic tse 1,6. Cellulose ha e qhibilihe hantle metsing, ha starch e qhibiliha ka metsing a chesang. Cellulose ha e na kutlo ho amylase 'me ha e fetohe e putsoa ha e pepesehetse iodine.
Ether ea selulose:
Lebitso la Senyesemane laether ea seluloseke cellulose ether, e leng motsoako oa polymer o nang le sebopeho sa ether se entsoeng ka cellulose. Ke sehlahisoa sa karabelo ea lik'hemik'hale ea cellulose (semela) e nang le moemeli oa etherification. Ho ea ka sehlopha sa sebopeho sa lik'hemik'hale sa sebaka se nkeloang sebaka ka mor'a etherification, e ka aroloa ka li-ether tsa anionic, cationic le nonionic. Ho latela moemeli oa etherification o sebelisitsoeng, ho na le methyl cellulose, hydroxyethyl methyl cellulose, carboxymethyl cellulose, ethyl cellulose, benzyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, cyanoethyl cellulose, benzyl cyanoethyl cellulose, carboxymethyl hydroxyethyl cellulose le phenyl cellulose, jj. Indastering ea kaho, cellulose ether e boetse e bitsoa cellulose, e leng lebitso le sa tloaelehang, 'me e bitsoa cellulose (kapa ether) ka nepo.
Mokhoa oa ho Tetefatsa oa Selulose Ether Thickener:
Li-thickeners tsa ether tsa cellulose ke li-thickeners tse seng tsa ionic tse teteanang haholo-holo ka ho nosetsa le ho kopana ha limolek'hule.
Ketane ea polymer ea ether ea cellulose e bonolo ho e etsa tlamo ea haedrojene le metsi ka metsing, 'me tlamo ea haedrojene e etsa hore e be le metsi a mangata le ho kopana ha limolek'hule.

Ka nako e ts'oanang, liketane tsa limolek'hule tsa ether ea cellulose li hokahane ho theha sebopeho sa marang-rang a mahlakore a mararo, 'me li-pigment, li-filler le likaroloana tsa latex li pota-potiloe bohareng ba letlooeng 'me li ke ke tsa phalla ka bolokolohi.
