Thensalu yopanda ulusi yopangidwa ndi singanoimatha kupirira kutentha kotsatira kwa 200℃ motsatira muyezo wouma wa kuthamanga.
Ngati pali madzi ndi mankhwala, zinthu zimapanga hydrolysis reaction. Nsalu yopanda nsalu yopangidwa ndi singano ndi polyester yofanana ndi polymer yomwe imasungunuka ndi kutentha kwambiri.
Nsalu yopanda ulusi yokhala ndi singano ndiyo njira yabwino kwambiri yosefera chifukwa cha kutentha kwambiri komwe polyester idzakhala yofooka komanso yosagwira ntchito. Kukana kwake kusinthasintha komanso kukana kutopa ndikwabwino kuposa ulusi wambiri wopangidwa.
Ulusi wa mankhwala wa nsalu zopanda ulusi wopangidwa ndi singano sungapakidwe sera mu pulasitiki yosatenthetsa kutentha, koma ukhoza kuphwanyidwa kapena njira zina zochizira pambuyo pogwiritsa ntchito njira zapadera.
Jin haocheng ndiopanga nsalu zopanda nsalukuchokera ku China.~
