Description
Other Names: Methoxy terminated polydimethylsiloxane
CAS No: 68951-97-3
Chemical Structure:
Methoxy Silicone Oil TPD-206 is a kind of structure control agent terminated by methoxy, its molecular weight is several times higher than that of dimethyldimethoxysilane, but its active group content is equivalent to hydroxy silicone oil. It has a good safety performance and it is not prone to yellowing. No water molecules are produced during the anti-structural process.
Technical Index
Item Typical Value Appearance Colorless transparent liquid, no impurities Viscosity(at 25°C, mm2/s) 5~7 (D4+D5), % 0~6 Methoxy Value, % 7.9 Refractive Index, 25°C 1.3950~1.4000
Application
It can be used as a structure control agent alone or in combination with hydroxy silicone oil when mixing high temperature rubbers. The heat treatment is not required when using, and the temperature should be raised after the feeding is mixed evenly. It shall not be exposed during storage to prevent hydrolysis reaction of methoxy with the water vapor in the air.
Packing
N.W 200KG hard plastic barrel or 1000KG IBC Tote.
