Description

Pss-Glycidyl-Heptacyclopentyl Substitut& CAS NO 230316-12-8 is a specialized organosilicon compound featuring a reactive glycidyl ether group and a complex heptacyclopentyl-substituted silsesquioxane (PSS) cage structure. This unique architecture provides exceptional thermal stability, low dielectric constant, and excellent mechanical reinforcement properties, making it a high-performance additive and precursor for advanced materials. It is primarily utilized by R&D and production teams in the electronics, aerospace, and high-performance polymer composites industries seeking to enhance material properties under demanding conditions.

Application

• Advanced Polymer Composites: Acts as a nanoscale reinforcing filler and crosslinking agent in epoxy, silicone, and polyimide resins to improve thermal stability, mechanical strength, and reduce dielectric constant.
• Electronic Encapsulants & Underfills: Used in formulations for semiconductor packaging to provide stress relief, enhance moisture resistance, and maintain electrical insulation at high temperatures.
• Low-k Dielectric Materials: Serves as a key precursor in the synthesis of porous, ultra-low dielectric constant films for next-generation microprocessors and integrated circuits.
• High-Temperature Coatings & Adhesives: Incorporated into protective coatings and adhesives for aerospace and automotive applications where resistance to thermal degradation is critical.
• Hybrid Organic-Inorganic Materials (ORMOSIL): Functions as a building block for creating tailored hybrid materials with combined organic flexibility and inorganic hardness for optical and sensor applications.
• Surface Modification Agent: The reactive glycidyl group allows for covalent bonding to various substrates (e.g., glass, metals, fibers) to modify surface properties like hydrophobicity, adhesion, and compatibility.
