Polyester POLYOL YA CPU
Mndandanda wa polyester polyols amagwiritsidwa ntchito kwambiri mu elastomers, ndipo malinga ndi zomwe makasitomala amafuna kuti asinthe kulemera kwa maselo.Zogulitsa zam'munsi zomwe zimapangidwa ndi ma polyols awa ali ndi mawonekedwe a kukana kuvala, kukana kupindika, kukana kung'ambika komanso mphamvu zamakina apamwamba.
Mndandanda wa polyester polyols chimagwiritsidwa ntchito m'munda wa kuponya polyurethane elastomers, makamaka ntchito mkulu kuuma polyurethane sieve mbale, casters, machira, mbale ndi mipiringidzo, kuumbidwa potting mankhwala.
