For procurement managers and R&D scientists in the chemical industry, understanding the nuances of specialty silicones is paramount. Hydroxy Terminated Polydimethylsiloxane, identified by CAS number 70131-67-8, stands out as a highly versatile and indispensable material. As a leading manufacturer and supplier, we aim to equip you with the knowledge to make informed purchasing decisions for this crucial OH Polymer.

What is Hydroxy Terminated Polydimethylsiloxane?

Also known as Hydroxyl Silicone Oil or OH Polymer, this compound is a functionalized polydimethylsiloxane. Its defining characteristic is the presence of hydroxyl (-OH) groups at the molecular chain ends. This specific chemical structure imparts unique reactivity and performance properties, making it a sought-after intermediate and base material across numerous sectors. When you're looking to buy this chemical, understanding its composition is the first step to ensuring optimal application performance.

Key Properties and Advantages

The appeal of CAS 70131-67-8 lies in its impressive property profile. It exhibits:

• Excellent Thermal Stability: Capable of withstanding extreme temperatures, typically from -50°C to +250°C, it ensures consistent performance in high-demand applications.
• Superior Electrical Insulation: Its dielectric strength makes it invaluable for electronic components, offering reliable protection and performance.
• Good Hydrophobicity: The silicone backbone provides excellent water-repellent properties, crucial for protective coatings and sealants.
• Chemical Inertness: It resists degradation from many chemicals, ensuring durability and longevity in various formulations.
• Controlled Reactivity: The terminal hydroxyl groups allow for cross-linking and further chemical modification, enabling its use in RTV silicones and other thermosetting systems.
