Description

Poly(Borodiphenylsiloxane) is a specialized organosilicon polymer incorporating boron into its siloxane backbone, offering unique thermal and chemical properties. This compound is valued for its ability to act as a high-temperature stabilizer, flame retardant, and a key intermediate in advanced material synthesis. It is essential for manufacturers in the plastics, high-performance resins, and specialty coatings industries seeking to enhance the thermal-oxidative stability and fire resistance of their products.

Application

• As a thermal stabilizer and antioxidant in high-temperature engineering plastics and silicones.
• As a flame retardant synergist in polymer composites, wire & cable insulation, and electronic encapsulants.
• As a precursor or cross-linking agent for synthesizing boron-modified siloxane resins and ceramics.
• In the formulation of high-temperature resistant coatings and adhesives for aerospace and automotive applications.
• As an additive for lubricants and greases to improve performance under extreme conditions.
• For research and development of novel hybrid inorganic-organic materials (HIOMs) with tailored properties.
