APIEZON n N-25G Vacuum grease Temperature range -269~ 30 ℃

N-25G

Vacuum grease

N-25G High Vacuum grease is a low temperature type high Vacuum grease. Operating temperature range is -269~ 30 ℃. Apiezon N has improved thermal conduction and crack-free performance, making it a good choice for some superconductor production applications.

Introduction

Apiezon N low-temperature high-vacuum grease is silicone-free and halogen-free, and is widely recognized and recommended as a low-temperature vacuum grease. This low-temperature grease is specially formulated to exhibit crack-free performance at low temperatures and withstand frequent cycles between -273°C and +30°C. Shelf life of 10 years (from the date of manufacture)

Features

Apiezon N Low Temperature High Vacuum Grease is a silicone-free and halogen-free low temperature vacuum grease with the following features:

• Withstands frequent cycling at low temperatures between -273°C and +30°C

• No cracks at low temperatures

• The ability to fill micropores adjacent to the surface improves thermal contact

• No contamination issues associated with silicone-based greases, such as 'creep' or 'hold-up'

• At 20°C, the vapor pressure is 6 x 10-10 Torr

• There is built-in radiation resistance

• It has a strong 'adsorption' ability to absorb potentially harmful greases and chemical impurities on metal and glass surfaces

• It is easy to clean and remove as it dissolves in hydrocarbons and chlorinated solvents

Apiezon N-type applications

1. Low temperature vacuum sealing: especially suitable for vacuum sealing of cryogenic systems, widely used to generate reliable vacuum and pressure-resistant sealing seals, including vacuum lines, Schlenk lines, cold traps, liquid helium hoses and electron microscopes.

It can guarantee vacuum lines, cold traps, electron microscope fiber optic ports, plug valves, grinding glass joints, faucets, and Slank Vacuum or pressure-resistant seals in wire and liquid helium hoses can also be used to improve the cryogenic annular sealing rubber ring by filling surface or annular defects.

2. Thermal coupling medium: It is very important for the cooling system to couple superconducting magnets, cryostats, temperature sensors or any system that must reach low temperature freezing as soon as possible, and it is an excellent choice for superconductor manufacturing applications.

3. Cryogenic sensor fixative

4. Sample retaining agent: used in low-temperature tests such as semiconductor chips, laser diodes and crystals, and used to improve the thermal contact between the sample ship and the cold head of the thermostat.

5. Application of ambient temperature - increase buffering: N vacuum grease has special additives to form a tough and elastic consistency to absorb equipment vibration, which is very important in connecting fragile glass to glass joints, such as burette faucets.
