PP saka jaka coating kayan ne polypropylene resin.
Polypropylene resin, shi ne wani tsari daidaitacce crystalline polymer, a light madara farin granules, dandani, ba guba, haske thermoplastic resin. A dangantaka yawa ne 0.90 ~ 0.91, shi ne mafi haske daga cikin general resin. Kayan aiki ne mai kyau, zafi juriya ne mai kyau, da melting point ne kusan 170 ℃, a karkashin babu waje tasiri, 150 ℃ ba deformation, chemical kwanciyar hankali ne mai kyau, juriya acid, alkali da kuma organic solvents, da mafi sinadarai magunguna (kamar smoking nitric acid, chromic acid bayani, halogen, benzene, carbon tetrachloride, chloroform, da dai sauransu) ba aiki, kuma kusan ba su sha ruwa. Rashin amfani da polypropylene shine sauƙin tsofafawa, ya zama mai laushi a lokacin da zafin jiki yake da ƙarancin zafin jiki, amma ana iya inganta shi ta hanyoyin ƙara ƙari, haɗuwa ko haɗuwa.
