Boleng:
1. Ponahalo: mokelikeli o se nang 'mala o nang le monko o khethehileng.
2. Boima: 1.071 g/cm³
5. Solubility: DMDBS e na le solubility e ntle 'me e ka qhibiliha ka mefuta e sa tšoaneng ea metsoako ea tlhaho.

Sebelisa:
1. DMDBS e sebelisoa haholo ho li-polymers tsa maiketsetso e le li-plasticizers, softeners le lubricant.
2. Ka lebaka la botsitso ba eona bo botle ba 'mele le lik'hemik'hale, DMDBS e ka boela ea sebelisoa e le plasticizer le softener bakeng sa li-resin tsa maiketsetso, lipente le liphahlo.
3. DMDBS e boetse e sebelisoa ka tloaelo ha ho etsoa lihlahisoa tse itseng tsa rabara, tse kang letlalo la maiketsetso, lieta tsa rabara le liphaephe tsa metsi.
