Description

Succinic Anhydride Terminated Polydimethylsiloxane, 75-100 Cst is a specialized organosilicon compound featuring reactive anhydride end groups on a polydimethylsiloxane (PDMS) backbone. This unique structure provides a versatile platform for chemical modification, enabling covalent bonding with amine or hydroxyl groups to create silicone-based polymers with tailored properties. It is essential for formulators and polymer chemists in industries requiring advanced surface modification, compatibilization, or the creation of hybrid organic-inorganic materials. The 75-100 centistoke viscosity indicates a low to medium molecular weight fluid, ideal for processing and blending.

Application

• Reactive Intermediate for Silicone-Modified Polymers: Used to synthesize block copolymers, graft copolymers, and silicone polyimides or polyamides.
• Surface Modifier and Coupling Agent: Improves adhesion and compatibility between organic polymers and inorganic fillers or substrates.
• Additive for Epoxy and Thermoset Resins: Acts as a flexibilizer and impact modifier, enhancing toughness while maintaining thermal stability.
• Lubricant and Release Agent Precursor: Serves as a base for creating high-performance, chemically bonded lubricants and mold release agents.
• Biomaterial and Medical Device Fabrication: Employed in creating biocompatible coatings and controlled-release drug delivery systems due to its reactive functionality.
• Textile and Fiber Treatment: Imparts durable water repellency, softness, and lubricity to synthetic and natural fibers.

Quality Control

Our Succinic Anhydride Terminated Polydimethylsiloxane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent functionality, viscosity, and anhydride content. Certificates of Analysis (COA) detailing key specifications such as assay, viscosity, and acid value are available upon request. We support our global partners with documentation to meet their quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). To prevent hydrolysis of the reactive anhydride groups, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) after opening.
