Is it good to use methoxy silicone oil as a structure control agent in the rubber compound?

Silicone rubber has excellent high and low temperature resistance, radiation resistance, hydrophobicity, electrical insulation, and physiological inertness and other special properties, it has become an indispensable new material in various fields and daily life. But to make good silicone rubber, not only the raw rubber and appropriate fillers must be selected, but also the structure control agent is an important partner.

1. Performance and use:

Methoxy-terminated structure control agent, its molecular weight is several times that of dimethyldimethoxy silane, but its active group content is equivalent to hydroxyl silicone oil. It has good safety performance, good rubber stiffness and is not prone to yellowing. No water molecules are produced during the anti-structuring process.

2. Main technical indicators:

1. Appearance: colorless transparent liquid

2. Viscosity (25℃, mm2/s): ≤20

3. Active group content: equivalent to 8.0% of hydroxyl content
