CAS 63148-57-2
:Polymethylhydrosiloxane
Description:
Polymethylhydrosiloxane (PMHS), with the CAS number 63148-57-2, is a silicone-based polymer characterized by its unique structure, which includes methyl and hydride groups attached to silicon atoms. This compound is known for its versatility and is commonly used as a silicone fluid or resin. PMHS exhibits excellent thermal stability, chemical resistance, and low surface tension, making it suitable for various applications, including sealants, adhesives, and coatings. Its hydrosilylation reaction capability allows it to participate in cross-linking processes, enhancing the mechanical properties of silicone elastomers. Additionally, PMHS is often utilized in the formulation of personal care products due to its skin-conditioning properties. The polymer is generally considered safe for use in consumer products, but appropriate handling and safety measures should be observed, as with any chemical substance. Overall, PMHS is valued for its functional properties and adaptability across multiple industries, including automotive, electronics, and cosmetics.
