Methyl phenyl polysiloxane

Description:
Methyl phenyl polysiloxane, with the CAS number 9005-12-3, is a type of silicone polymer characterized by its unique structure, which includes alternating silicon and oxygen atoms, along with methyl and phenyl groups attached to the silicon. This compound exhibits excellent thermal stability, chemical resistance, and low surface tension, making it suitable for various applications. It is often used as a lubricant, surfactant, or in formulations requiring enhanced wetting properties. The presence of phenyl groups imparts improved thermal and oxidative stability compared to standard methyl siloxanes, while the methyl groups contribute to flexibility and lower viscosity. Methyl phenyl polysiloxane is also known for its hydrophobic characteristics, which can be beneficial in coatings and sealants. Additionally, it is utilized in the cosmetics industry for its smooth application and skin feel. Overall, this silicone polymer is valued for its versatility and performance in diverse industrial and consumer applications.
