Description

Cyclosiloxanes, Di-Me, Polymers With Me Ph Cyclosiloxanes, Me Vinyl Cyclosiloxanes And Vinyl Group-Terminated Di-Me Siloxanes is a specialized silicone copolymer engineered for high-performance applications requiring tailored reactivity and physical properties. This versatile material is valued for its unique combination of phenyl, vinyl, and methyl functional groups, which allows for precise modification of characteristics like refractive index, thermal stability, and crosslink density. It is essential for formulators and manufacturers in the personal care, electronics, and advanced materials sectors seeking to develop superior, customized silicone-based products.

Application

• Silicone Resin & Rubber Modifier: Acts as a reactive intermediate to enhance the thermal stability, refractive index, and mechanical strength of high-performance silicone resins and rubbers.
• Personal Care & Cosmetic Ingredients: Used in premium hair care and skincare formulations to provide exceptional shine, softness, and conditioning without greasiness.
• Release Coatings & Pressure-Sensitive Adhesives (PSAs): Serves as a key component in formulating controlled-release coatings for labels and tapes, and in modifying the adhesive properties of PSAs.
• LED Encapsulation & Optical Materials: Employed in the production of clear, high-refractive-index encapsulants for LEDs and other optical devices due to its excellent light transmission and thermal properties.
• Crosslinking Agent for Silicone Elastomers: Functions as a reactive crosslinker in addition-cure (platinum-catalyzed) silicone systems, allowing for the creation of elastomers with specific hardness and elongation properties.
• Surface Treatment & Co-additive: Used to modify surface properties of materials, improving water repellency, lubricity, and compatibility in composite systems.

Quality Control

Our Cyclosiloxanes, Di-Me, Polymers With Me Ph Cyclosiloxanes, Me Vinyl Cyclosiloxanes And Vinyl Group-Terminated Di-Me Siloxanes is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assessment of vinyl content, phenyl content, viscosity, and refractive index, to ensure consistent performance and purity for your formulations. Certificates of Analysis (COA) detailing all specifications are available upon request.

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 strong acids and organic solvents. For long-term storage, consider storing under an inert atmosphere (e.g., nitrogen) to maintain optimal reactivity of the vinyl groups.
