Key Benefits & Features
Broad Viscosity Range: Precise molecular control delivers tailored viscosity grades from thin lubricating films to heavy-damping polymer matrix buffers.
Thermal & Oxidation Resistance: Functions consistently across extreme temperature windows from -50°C to over 200°C without significant structural degradation.
Low Surface Tension: Excellent spreading and wetting characteristics, crucial for surface coating consistency and mold-release applications.
High Shear Stability: Retains its viscosity index and internal damping integrity under massive continuous physical shear forces.
High purity:low acid value,low volatile content,C3H9N free,K+/Na+ free.
Applications
Industrial Lubricants & Damping: Critical component in mechanical shock absorbers, hydraulic systems, and extreme-pressure gear assemblies.
Release Agents: Acts as a clean, non-carbonizing release medium for plastics, rubber molding, and die-casting processes.
Personal Care & Cosmetics: Utilized under the cosmetic name Dimethicone to provide smooth skin-feel, barrier protection, and conditioning benefits in lotions, skin creams, and hair care formulations.
Process Defoaming: Highly effective non-aqueous antifoaming agent for petroleum refining, chemical synthesis, and blending processes.
