EPP ndi yachidule ya Expanded polypropylene, mtundu watsopano wa pulasitiki wa thovu.EPP ndi polypropylene pulasitiki thovu zakuthupi, ndi mtundu wa ntchito bwino kwambiri crystal polima/gasi composite zakuthupi, ndi ntchito yake yapadera ndi apamwamba wakhala fulumizitsa kuteteza chilengedwe cha latsopano compressive bafa kutentha kutchinjiriza zipangizo.

EPP ndi zinthu zoteteza zachilengedwe zomwe zitha kubwezeretsedwanso.Poyerekeza ndi EPS (yokulitsidwa polystyrene), EPP ili ndi mphamvu zamakina apamwamba, kukulitsa kwambiri mawonekedwe ogwiritsira ntchito mapulasitiki a thovu.EPP ili ndi mphamvu yokoka yopepuka, kutsika bwino, kukana zivomezi, kuchuluka kwa mapindikidwe apamwamba, kuyamwa bwino, kukana mafuta, kukana kwa asidi, kukana kwa alkali, zosungunulira zamitundu yosiyanasiyana, mayamwidwe osagwiritsa ntchito madzi, kutchinjiriza, kukana kutentha (-40 ~ 130 ℃) , sanali poizoni ndi zoipa, akhoza 100% zobwezerezedwanso ndi pafupifupi palibe kuchepa ntchito, ndi kwenikweni zachilengedwe wochezeka thovu pulasitiki.Mikanda ya EPP imatha kupangidwa kukhala mawonekedwe osiyanasiyana azinthu za EPP mu nkhungu yamakina omangira.

Welleps Technology Co., Ltd. yakhala ikuyang'ana kwambiri pakupanga ndi kupanga makina a EPS / EPP / ETUP ndi nkhungu kwazaka zopitilira 15.Kampaniyo ili ndi gulu la akatswiri kuti lipatse makasitomala mapangidwe amakina, kupanga ndi kugulitsa pambuyo pogulitsa.EPP Vacuum System Shape Molding Machine imagwiritsidwa ntchito kupanga mitundu yonse ya zinthu zamtengo wapatali zopangira ma EPP (monga makompyuta apakompyuta, zowonetsera zamadzimadzi, zida zolondola), Zoseweretsa za EPP (mitundu ya ndege), zida zamagalimoto apamwamba a EPP (EPP bumper, EPP toolbox, EPP sunshade etc.), katundu wamasewera wa EPP (Surfboard, helmet, etc.).
