CAS 70131-67-8: Polysiloxanes, di-Me, hydroxy-terminated

Description: Polysiloxanes, di-Me, hydroxy-terminated, commonly referred to as hydroxyl-terminated polydimethylsiloxane (PDMS), are a class of silicone polymers characterized by their repeating siloxane (Si-O) units. These compounds typically exhibit a linear structure with methyl groups (Me) attached to the silicon atoms and hydroxyl (–OH) groups at the terminal ends. This structure imparts unique properties, including flexibility, low surface tension, and excellent thermal stability, making them suitable for a variety of applications. They are often used as intermediates in the synthesis of silicone elastomers, sealants, and coatings due to their ability to form strong bonds with other materials. Additionally, their hydrophobic nature and low toxicity make them valuable in cosmetic formulations and medical applications. The presence of hydroxyl groups allows for further chemical modification, enhancing their versatility in various industrial processes. Overall, polysiloxanes with this specific structure are integral to many fields, including materials science, pharmaceuticals, and consumer products.
