General Description

Methoxy terminated polydimethylsiloxane is a type of silicone polymer that is terminated with methoxy groups at both ends. It is commonly used as a lubricant, surfactant, and release agent due to its low surface tension and excellent thermal stability. This chemical is often incorporated into various industrial and consumer products such as personal care products, lubricants, and coatings. Methoxy terminated polydimethylsiloxane exhibits good moisture resistance, UV stability, and non-toxicity, making it a versatile and widely used material in various applications.
