Widely used as a base polymer in silicone elastomers and sealants due to its flexibility and thermal stability. Commonly employed in mold making for casting resins, concrete, and wax because it captures fine details and releases easily. Used in personal care products such as skin creams and hair conditioners for its smooth, non-greasy feel and moisture barrier properties. Acts as a defoaming agent in industrial processes including fermentation, wastewater treatment, and food processing. Frequently utilized in microfluidic device fabrication through soft lithography, where it is cured and bonded to form fluid channels. Also serves as a release agent in manufacturing and as a lubricant in medical devices due to its biocompatibility and low surface tension.
