Specialty Polyether-Low Molecular Weight PET Polyether
Katundu ndi Ntchito
Ndi madzi ozizira kutentha, omwe ndi abwino kugwiritsa ntchito ndi kukonza. Galasi kusintha kutentha kwa -80 ℃, ndi ntchito kwambiri otsika kutentha, katundu makina elastomer mankhwala ake ndi PTMG pafupi PTMG, akhoza m'malo PTMG mu nkhanza otsika kutentha chilengedwe.
Ndi zabwino maselo kusinthasintha, akhoza m'malo PTMG mu kusintha yokumba chikopa ndi inki yosindikiza; itha kugwiritsidwa ntchito muzomatira zosagwirizana ndi kutentha, zokutira, polyurethane elastomers ndi zina zotero.
