Product Overview

Dimethyl polysiloxane (20 cSt) LR is a high-purity, low-viscosity silicone fluid designed for precision laboratory applications. This laboratory-grade polysiloxane offers excellent thermal stability, water repellency, and chemical inertness, making it a versatile choice for analytical procedures, lubrication, and antifoaming requirements. With a kinematic viscosity of 20 centistokes (cSt), it ensures smooth flow and consistent performance in sensitive instruments and processes. The LR (Laboratory Reagent) grade guarantees minimal impurities, ensuring reliable results in critical experiments. Its non-reactive nature makes it compatible with a wide range of materials, including glass, metals, and most plastics. Whether used as a calibration fluid, release agent, or protective coating, this dimethyl polysiloxane maintains stability across a broad temperature range, from -40°C to 200°C. The liquid form allows for easy dispensing and precise volume control, reducing waste and improving efficiency in lab workflows.

FAQs

1. What is the viscosity range of Dimethyl Polysiloxane 20 cSt LR?

This product has a kinematic viscosity of 20 centistokes (cSt) at 25°C, which is ideal for applications requiring moderate flow characteristics.

2. Is this polysiloxane compatible with rubber or silicone-based materials?

While generally inert, prolonged contact with certain rubbers or silicones may cause swelling or degradation. Always test compatibility before extended use.

3. Can this be used as a substitute for higher-viscosity silicone oils?

For applications requiring thicker lubrication, higher-viscosity grades (e.g., 50 cSt or 100 cSt) are recommended, as 20 cSt may not provide sufficient film strength.
