TRP ke eng?
TRP (Thermoplanestic raber) Ka tloaelo e na le lebitso la 23% PS le 77% Buadiene. E hlophisitsoe ke emulsion ka mokhoa o khabisitsoeng ke polyers e kopaneng. Ts'ebetso ena e etsa lingoliloeng tse tloaelehileng tse nang le lekhulo la ntlo, le matrix ea khale, e thata ea lintho tsa thermoplast. Liphetho li hlahisoa ke thepa ho tsoa linthong ka bobeli empa e khona ho sebetsoa ka mokhoa o hlakileng haholo oa lisebelisoa tsa enjene. Ho fumana lintlha tse eketsehileng, sheba tataiso ea rona raber ea Thermoplastics.

Li-li-ruri tse tloaelehileng li tsamaisoa kapa li hloekisoa ka foromo e halikiloeng ka mokhoa o itseng, 'me mocheso o sebelisoa ho phethela ts'ebetso ea lits'itiso. Tabeng ea TRP, karolo ea Buadiene e etsoa e hokahaneng ka botlalo e bile e hlahisoa e le phofo e ntle. Motsoako oa PS ka nako eo o tsamaisana le ho hokela sefapano ka ho phunya rabara bakeng sa mochini o matla oa polymer matrix. Ho feto-fetoha ha maemo ho fella ka ho hlaka ha karolo ea bo-butadiene, moo ho qaqileng ea rabara ha e le hantle.

TPU ke eng?
Polymers ea TPU e entsoe ka meaho e sa feleng, [e bonolo "likarolo tsa khararization e phahameng haholo. Li-covalents tse kopaneng lipakeng tsa mefuta e 'meli ea karolo e kopantsoeng le liketane tse koahelang thepa e tsoang linthong tsena ka bobeli. Ka ho fetola boima ba limolek'hule le bolelele ba likarolo tsa mmiti, thepa e ngata e ka nkuoa ho lisebelisoa tsa lik'hemik'hale (hoo e batlang e le). Boemo ba khase ea khalase ba likarolo tse peli ba ka tšoana kapa ba sepala, 'me ba ka fetoloa ho ba phahameng kapa ba tlase. Litaba tsena tsa ts'ebetso li lumella tlhahiso ea thepa e mengata ea malapa a mangata.
