Description

Cyclosiloxanes, Di-Me, Polymers With Me Ph Cyclosiloxanes And Vinyl Group-Terminated Di-Me Siloxanes is a specialized organosilicon copolymer designed for high-performance applications. This product matters because it combines the thermal stability and low-temperature flexibility of polydimethylsiloxanes with the enhanced compatibility and reactivity provided by phenyl and vinyl functional groups. It is essential for manufacturers in the silicone rubber, advanced adhesives, and release coating industries who require tailored rheological properties and crosslinking efficiency. The CAS number for this compound is provided in the table below.

Application

• High-Performance Silicone Elastomers: Acts as a key reactive intermediate or additive to enhance the mechanical strength, thermal stability, and crosslink density of molded and extruded silicone rubber parts.
• Pressure-Sensitive Adhesives (PSAs) & Sealants: Imparts improved adhesion, flexibility, and environmental resistance to formulations for tapes, labels, and construction sealants.
• Release Coatings: Used in the formulation of durable, non-stick release liners for labels, graphic arts, and industrial processes.
• Silicone Resins & Encapsulants: Serves as a modifying agent in resins for electrical insulation, potting compounds, and protective coatings, offering enhanced compatibility with organic matrices.
• Personal Care & Cosmetic Ingredients: Functions as a conditioning agent, emollient, or film-former in hair care and skincare products, providing a silky, non-greasy feel.
• Fabric & Fiber Treatments: Applied as a softener, water repellent, or finishing agent for textiles and non-wovens.

Quality Control

Our Cyclosiloxanes, Di-Me, Polymers With Me Ph Cyclosiloxanes And Vinyl Group-Terminated Di-Me Siloxanes undergoes rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Key parameters such as vinyl content, phenyl content, viscosity, and refractive index are strictly monitored. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. This material is moisture-sensitive; ensure containers are sealed when not in use to prevent absorption of atmospheric moisture.
