Silico® PF8260 Polymethylphenylsiloxane
Silico®-PF8260 (CAS 63148-58-3) is a high-performance polymethylphenylsiloxane fluid with excellent thermal stability, oxidation resistance, and electrical insulation. Its phenyl groups improve low-temperature flexibility and high-temperature resistance compared to PDMS. This colorless, transparent liquid is chemically inert and ideal for electronics, coatings, lubricants, and cosmetics.
Product Introduction:
Silico®-PF8260 (CAS 63148-58-3 PMPS) is a high-performance polymethylphenylsiloxane fluid designed to deliver outstanding thermal stability, oxidation resistance, and electrical insulation.
By incorporating phenyl groups into the siloxane backbone, PF8260 offers significantly improved low-temperature flexibility and high-temperature resistance compared to standard polydimethylsiloxane (PDMS).
It is a colorless, transparent liquid with excellent chemical inertness and compatibility with organic materials, making it ideal for a wide range of demanding applications across electronics, coatings, lubricants, and cosmetics.
