Unique molecular structure endows excellent low-temperature flexibility, maintaining good fluidity at -60℃. It acts as high-performance lubricant for aerospace precision moving components. The product delivers stable friction reduction performance within wide temperature range, resisting oxidation and aging, widely used for aviation, aerospace and cryogenic mechanical equipment lubrication.

Product Detail

Product Overview

125cst Methyl Phenyl Silicone Oil (CAS 63148-58-3) is synthetic methyl phenyl polysiloxane. Compared with ordinary dimethyl silicone oil, it achieves better low-temperature fluidity while retaining silicone’s intrinsic heat resistance. Formulated for extreme cold working conditions, this silicone lubricant solves the problems of lubricant solidification, viscosity surge and ineffective lubrication under low temperature. It is an ideal special lubricating medium for aerospace and cryogenic industrial facilities.

Key Features

Excellent low-temperature resistance, maintains fluidity at -60℃
Small viscosity variation with temperature, stable lubricating capacity
Low pour point, avoids solidification in ultra-low temperature environment
Good anti-oxidation property, long service cycle
Chemical inertness, non-corrosive to metal alloy precision parts

Main Applications

Lubricant for aerospace precision mechanical components
Aviation equipment operating in high-altitude low-temperature environment
Cryogenic test chamber and low-temperature experimental apparatus
Outdoor machinery and instruments used in frigid regions
Bearings, sliding parts under wide temperature fluctuation conditions

Usage Guidance

Suitable for bearing, gear, guide rail and precision transmission component lubrication. Can be used via oil dripping, brushing or circulating oil supply. Do not mix with mineral oil, hydrocarbon lubricants, acid and alkaline substances. Keep the system sealed to prevent moisture and particle contamination.

Storage & Package

Seal drums tightly. Store in cool, dry and ventilated warehouse. Keep away from strong oxidants and direct sunlight. Standard package: 25kg plastic drum, 200kg iron drum. Shelf life: 12 months under proper storage conditions.

Service Support

Test samples are available for low-temperature performance testing. Stable bulk supply and professional technical support. Welcome to inquire TDS, COA and factory direct quotation.
