I-Polypropylene (PP) iyithemoplastic ehlukahlukene eyaziwa ngokumelana kwayo kahle namakhemikhali, ukuminyana okuphansi, ukumelana nokukhathala okuhle, nokubiza kwayo. Ibonisa ukuqina okuphezulu, amandla okushaya kahle (ikakhulukazi kumafomu e-copolymer), nokucubungula okuhle kakhulu. Ama-compound e-PP asetshenziswa kabanzi ezimotweni, ezimbonini, ezintweni zabathengi, nasezintweni zokupakisha ngenxa yokulinganisela kwawo okuhle kokusebenza nenani.

Ukuguqulwa kwe-PP ngokuhlanganiswa ne-glass fiber, izinto zokugcwalisa amaminerali, izivimbeli zomlilo, izithuthukisi zokushaya, nama-antioxidants kukhiqiza ukuthuthukiswa okukhulu ezicini zempahla eyisisekelo.

Inkcazelo Yomkhiqizo: 10%-30% Umgexo Womkhuhlane; i-talc, i-barium sulfate, noma i-calcium carbonate njengomgexo. Ukuqina okuphezulu, akukho phunga, futhi konga imali.

Inkcazelo yomkhiqizo: I-PP egcwalisiwe eqinisiwe futhi engamelana namazinga okushisa aphansi. Yakhiwe nge-10%-30% yezinto ezigcwalisa amaminerali nama-elastomeric toughening agents ukuze kuthuthukiswe amandla okushaya ngisho namazinga okushisa aphansi. Ilungele izimoto, izimboni, kanye nezimpahla zabathengi ezidinga ukuqina nokusebenza kahle kwezindleko. Ayinuki futhi kulula ukuyicubungula.

Inkcazelo yomkhiqizo: 20%-50% i-glass fiber. Amandla aphezulu, ukuhamba kahle komkhiqizo, futhi akulula ukugoba nokuhlanekezela.

Incazelo yomkhiqizo: Ukuhamba kahle, ukuqina okuphezulu, ukuminyana okuphansi, intuthu encane, nokugqwala okuncane ezikhunjeni.
