Applications of 68083-19-2
| Industry | Application | Process |
|---|---|---|
| Rubber & Plastics | Base polymer for silicone rubber and silicone resins | Serves as the base polymer in addition-cure liquid silicone rubber (LSR) or high-temperature vulcanizing (HTV) silicone rubber, undergoing addition curing with hydrogen-containing siloxanes under catalytic conditions. |
| Rubber & Plastics | Raw polymer for compounded rubber | Acts as the primary elastomer in compounded rubber formulations; compounded with reinforcing fillers (e.g., fumed silica) and additives, then processed via mixing, preheating, and compression molding to produce solid silicone rubber products. |
| Electronics & Electrical Appliances | Electronic encapsulants and conformal coatings | Applied via addition-cure mechanism to encapsulate or coat electronic components, providing moisture resistance, dust protection, and electrical insulation. |
| Mold Manufacturing | Precision mold rubbers and pad printing silicones | Processed via addition-cure vulcanization to produce high-precision, low-shrinkage soft molds for replicating resin crafts, candles, food items, and precision mechanical parts. |
| Medical & Food-Contact Applications | Medical tubing and food-grade articles | Processed via platinum-catalyzed addition-cure vulcanization to yield non-toxic, odorless, physiologically inert materials suitable for medical devices and food-contact applications. |
| Coatings & Inks | Silicone-based coatings and release coatings | Functions as the film-forming component; crosslinked and cured to form heat-resistant, weather-resistant, and release coatings. |
| Textiles & Leather | Fabric finishing agents and softeners | Applied to fabric surfaces after emulsification or dissolution, imparting smoothness, softness, and elasticity. |
| Chemical Raw Materials | Intermediate for silicone-modified materials | Utilizes the reactive vinyl double bond in graft copolymerization or block copolymerization reactions to modify polyolefins or acrylic resins. |
