Usage

General Description

POLY(METHYLSILSESQUIOXANE), also known as PMSQ, is a type of silicone-based polymer that is commonly used in a variety of applications due to its unique properties. This chemical is a highly cross-linked, three-dimensional network of siloxane units, which gives it excellent thermal and oxidative stability, as well as good mechanical strength and flexibility. PMSQ is often used as a coating or film-forming agent in electronic devices, optical coatings, and as a protective barrier in aerospace and automotive industries. It is also frequently incorporated into cosmetic and skincare products for its ability to impart a smooth and silky feel to the skin. The versatility and performance of POLY(METHYLSILSESQUIOXANE) make it a valuable component in a wide range of industrial and consumer applications.
