Ndi kapu ya pulasitiki yamtundu wanji yomwe ingakhale ndi madzi otentha

PP polypropylene zakuthupi, Tritan, polycarbonate (PC), polyphenylsulfoxide (PPSU) makapu apulasitiki akhoza kudzazidwa ndi madzi otentha.PP polypropylene chuma ndi chikhalidwe kwambiri polima zinthu, mtengo wake ndi wotchipa, ndipo linanena bungwe lalikulu, akhoza bwino kukwaniritsa zofunika ogula.Kutentha kwa kusintha kwa galasi kumakhala pafupifupi -10 ° C, koma kukana kutentha kumatha kupitilizidwa ndi crystallization, ndipo madzi otentha amatha kuikidwa.

Chiyambi cha Tritan
Ichi ndi chimodzi mwazinthu zabwino kwambiri zopangira PC pakali pano, zotetezeka kuposa PC, palibe bisphenol A vuto lotulutsa, ndi Mtundu watsopano wa copolyester wosamva kutentha kwambiri, kutentha kwa kutentha kwa 109 ° C, kumatha kudzazidwa ndi madzi otentha. , ndipo imatha kupirira kupha tizilombo toyambitsa matenda.
