Ipayipi lensimbi eliboshweikhiqizwa ngepulasitiki yokunameka esekelwe epayipini elishiselwe elinobubanzi obuvunguzayo kanye nepayipi elishiselwe imvamisa ephezulu. Ubukhulu bepayipi ububanzi bungu-1200mm. I-Polyvinyl chloride (PVC), i-polyethylene (PE), i-epoxy ingafakwa kuye ngezidingo ezahlukene. I-resin (EPOZY) nezinye izimbobo zepulasitiki ezinezakhiwo ezihlukene, ukunamathela okuhle, ukumelana nokugqwala okuqinile, ukumelana nama-acids aqinile, ama-alkali aqinile nokunye ukugqwala kwamakhemikhali, okungewona ubuthi, okungagqwali, ukumelana nokuguga, ukumelana nomthelela, futhi kuqinile. ukumelana nokungena, Ingaphezulu lepayipi libushelelezi futhi alinamatheli kunoma iyiphi into, enganciphisa ukumelana ngesikhathi sokuthutha, ikhulise izinga lokugeleza nokusebenza kahle kokuhamba, futhi inciphise ukulahlekelwa kwengcindezi yokuhamba. Ayikho i-solvent kanye ne-exudate into enamathela, ngakho-ke ngeke ingcolise i-medium edluliswayo, ukuqinisekisa ukuhlanzeka nokuhlanzeka koketshezi. Ingasetshenziswa ngokushintshana ngemijikelezo ebandayo neshisayo ebangeni -40 ℃ kuya ku-+80 ℃, ngaphandle kokuguga, Ayiqhekeki, ngakho ingasetshenziswa ezindaweni ezinokhahlo njengezifunda ezibandayo.
