Applications of 70131-67-8
| Industry | Application | Process |
|---|---|---|
| Organosilicon Materials | Base polymer for silicone rubber | Heated and vulcanized with crosslinkers, fillers, and other additives to produce room-temperature vulcanizing (RTV) or high-temperature vulcanizing (HTV) silicone rubber |
| Organosilicon Materials | Raw material for silicone oil modification | Modified silicone oils are synthesized via end-group reactions (e.g., hydrosilylation with hydride-containing silicone oils) for use in fabric softeners, defoamers, etc. |
| Cosmetics | Additive for personal care products | Added as an emollient and skin-conditioning agent to emulsions and creams to impart a silky feel and film-forming properties |
| Coatings & Inks | Leveling agent and surface-modifying additive | Incorporated into coating systems to improve leveling, anti-cratering performance, and surface slip |
| Medical Devices | Raw material for medical-grade silicone rubber products | Used to manufacture biocompatible silicone rubber components such as catheters and implants, prepared via platinum-catalyzed addition-cure vulcanization |
