Ubwino
1. Kulemera kochepa kumawapangitsa kukhala opepuka.
2. Zipangizo zabwino kwambiri zotetezera kutentha ndi phokoso.
3. Kukana bwino kukhudzana ndi mankhwala.
4. Sizimawononga kapena kuwononga ndipo sizimalowa madzi.
5. Chifukwa cha kuuma kwake kwamkati kochepa, kutayika kwa katundu kumakhala kochepa.
6. Sizimawonjezera ma oxide achitsulo m'madzi.
7. Kukana mwamphamvu kugwedezeka komanso kukana kuthamanga kwambiri, chifukwa zimatha kuwonjezera kutalika zisanasweke.
Chiyambi cha Zamalonda
PPSU ndi pulasitiki yotentha yopanda mawonekedwe komanso yowonekera bwino komanso yokhazikika kwambiri ya hydrolytic. Chogulitsachi chikhoza kuphikidwa mobwerezabwereza ndi nthunzi. Ndipo monga chinthu chomwe chimapirira kutentha kwambiri, kutentha kwake kumakhala kokwera mpaka madigiri 207. Chifukwa cha kutentha kwambiri mobwerezabwereza, kuphikidwa ndi nthunzi. Chimalimbana bwino ndi mankhwala komanso asidi ndi alkali, chimatha kupirira mankhwala amadzimadzi ndi sopo, sichingasinthe mankhwala. Chopepuka, cholimba kugwa, ndiye chabwino kwambiri pankhani ya chitetezo, kukana kutentha, kukana hydrolysis ndi kukana kukhudza.
Mapaipi olumikizirana opangidwa ndi zinthu za PPSU amatha kupirira kugwedezeka mwamphamvu komanso mankhwala popanda kuwonongeka. Mapaipi olumikizirana a PPSU ndi ofulumira kuyika, osavuta kuyika, otseka bwino, amaonetsetsa kuti kulumikizana kuli kotetezeka kwa nthawi yayitali, ndipo amapeza phindu lalikulu, motero amachepetsa ndalama zogwirira ntchito. Mapaipi awa ndi opanda fungo komanso osakoma, oyenera kumwa madzi akumwa.
