Description

Cyclosiloxanes, Di-Me, Polymers With 1,3-Diethenyl-1,3-Dimethyl-1,3-Diphenyldisiloxane is a specialized organosilicon copolymer designed to impart unique properties to advanced material formulations. This compound matters for its ability to act as a reactive intermediate or modifier, enhancing thermal stability, flexibility, and compatibility in high-performance systems. It is primarily needed by manufacturers in the silicone elastomer, specialty resin, and advanced adhesive industries seeking to fine-tune material characteristics.

Application

• As a reactive modifier in the synthesis of high-temperature resistant silicone elastomers and rubbers.
• As a cross-linking agent or chain extender in the production of specialty silicone resins for coatings and encapsulants.
• As a key intermediate for manufacturing pressure-sensitive adhesives (PSAs) with tailored tack and peel strength.
• In the formulation of release coatings for labels and industrial tapes.
• As an additive to improve the flexibility and impact resistance of thermoset plastics and composites.
• For research and development of novel silicone-based materials with specific optical or dielectric properties.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Production follows strict protocols to guarantee batch-to-batch consistency in composition, viscosity, and reactivity. Certificates of Analysis (COA) detailing key parameters are available upon request to support your quality assurance and regulatory needs.

Storage

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