Ndi madzi ozizira kutentha, omwe ndi abwino kugwiritsa ntchito ndi kukonza. Galasi kusintha kutentha kwa -80 ℃, ndi ntchito kwambiri otsika kutentha, mawotchi zimatha elastomer ali pafupi ndi PTMG.

Amagwiritsidwa ntchito kwambiri popanga ma propellant olimba, okhala ndi zida zamakina otsika kwambiri komanso kutentha kosiyanasiyana.

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.
