Alfa Aesar™ Octamethylcyclotetrasiloxane, 98%
Manufacturer: Alfa Aesar™ A1524022
Description
ApplicationsOctamethylcyclotetrasiloxane is used to prepare silicone oil, silicone rubber and silicone resin having different degrees of polymerization through ring opening and polymerizing. It is also widely used in various fields viz. construction, electronics, textile, automobile, personal care, food, and machining. It is an organometallic reagent utilized for the preparation of siloxane polymers having high surface-hydrophobicity restoration.
Solubility
Immiscible with water.
Notes
Incompatible with strong oxidizing agents, acids and bases.
