INDUSTRY COMPONENT

Damping Fluid

Specialized silicone-based fluid engineered for controlled motion resistance in soft-close dampers.

Component Specifications

Definition

A high-viscosity, temperature-stable silicone fluid formulated specifically for hydraulic damping applications in soft-close mechanisms. It provides consistent resistance to motion through internal shear forces, ensuring smooth deceleration without impact or noise.

Working Principle

Operates on the principle of viscous shear damping: as the damper piston moves through the fluid, internal friction converts kinetic energy into heat, creating controlled resistance that slows motion proportionally to velocity.

Materials

Polydimethylsiloxane (PDMS) silicone base with viscosity modifiers and anti-wear additives; typically ISO VG 1000-5000 grade; operating temperature range: -40°C to 150°C.

Technical Parameters

Color Clear
Density 0.97 g/cm³
Viscosity 3000 cSt at 25°C
Pour Point -50°C
Flash Point >300°C

Standards

ISO 3448, DIN 51519
