Iphepha le-PP liyimpahla e-semi-crystalline. Liqinile kwaye linendawo yokunyibilika ephezulu kune-PE. Ngenxa yokuba ubushushu be-PP be-homopolymer bubuthathaka kakhulu ngaphezu kwe-0C, izinto ezininzi ze-PP zorhwebo zii-copolymers ezingacwangciswanga ezine-ethylene eyi-1 ukuya kwi-4% okanye ii-clamp copolymers ezinomxholo ophezulu we-ethylene.
Iphepha le-PP elicocekileyo linoxinano oluphantsi, kulula ukulidibanisa nokulicubungula, linokumelana okuphezulu kweekhemikhali, ukumelana nobushushu kunye nokumelana nempembelelo, alinatyhefu kwaye alinancasa, kwaye okwangoku lelinye lawona maplastiki obunjineli anobuhlobo nokusingqongileyo. Imibala ephambili imhlophe, umbala we-microcomputer, kwaye eminye imibala inokwenziwa ngokwezifiso ngokweemfuno zabathengi. Izicelo: izixhobo ezichasene ne-asidi kunye ne-alkali, abavelisi bamaphepha e-pp.
Iphepha elikhutshiweyo lePolypropylene (PP) liphepha leplastiki elenziwe ngokongeza izongezo ezahlukeneyo ezisebenzayo kwi-resin yePP ngokusebenzisa i-extrusion, i-calendar, i-cooling, i-cutting kunye nezinye iinkqubo.
Iphepha lePP eliqinisiweyo lefayibha yeglasi (iphepha le-FRPP): Emva kokuba liqiniswe yifayibha yeglasi engama-20%, ukongeza ekugcineni ukusebenza okugqwesileyo kokuqala, amandla kunye nokuqina kuphindwe kabini xa kuthelekiswa ne-PP, kwaye linokumelana okuhle nobushushu kunye nokumelana okuphantsi kwempembelelo yobushushu, ukumelana ne-arc yokulwa nokugqwala, ukuncitshiswa okuphantsi. Ifanelekile ngokukodwa kwifayibha yamakhemikhali, i-chlor-alkali, ipetroli, idayi, izibulala-zinambuzane, ukutya, amayeza, ishishini lokukhanya, isinyithi, unyango lwamanzi amdaka kunye neminye imimandla.
Iphepha le-PPH lisetyenziswe ngempumelelo ekuvelisweni kwamaphepha, kwaye ubuchwepheshe obuphambili bukwindawo ephambili eTshayina. Ezi mveliso zingasetyenziselwa iipleyiti zokucoca kunye nezikhongozeli ze-spiral wound, amaphepha eplastiki aqinisiweyo eplastiki eqinisiweyo, ukugcinwa kweshishini le-petrochemical, iinkqubo zothutho kunye neenkqubo zokulwa nokugqwala, izikhululo zamandla, unikezelo lwamanzi, iinkqubo zonyango lwamanzi kunye nokukhupha amanzi kwizikhululo zamanzi; kunye nezikhululo zentsimbi, izikhululo zamandla Ukususwa kothuli, iinkqubo zokuhlamba kunye nokungenisa umoya, njl.
