APIEZON n L-25G Vacuum grease without silica and halogen

L-25G

Vacuum grease

L-25G Ultra-high Vacuum grease has excellent vapor pressure characteristics and can be used in ultra-high vacuum environments. The vacuum degree of Apiezon L-type vacuum sealing grease is 7.0x10 ^ (-11) Torr

Introduction

Apiezon L-25GUltra-high vacuum greasebeApiezon L series ultra-high vacuum grease with a content of 25g,Also known as grease, it is a silicone-free, halogen-free, ultra-high vacuum grease suitable for scientific and industrial use. Apiezon L grease has very good vapor pressure characteristics in all Apiezon products, making it suitable for use in ultra-high vacuum applications. Grease is often used by credible organizations such as the European Space Agency, NASA and NATO.

Apiezon L vacuum grease is typically used at room temperature (typically 10 to 30°C / 50 to 86°F). Shelf life of 10 years (from the date of manufacture)

Features

Apiezon L Vacuum Grease is a silicone-free, halogen-free, ultra-high vacuum grease with the following features:

• The vapor pressure displayed at 20°C is extremely low at 7x10^-11 torr

• Free from contamination issues associated with silicone-based greases, such as 'creep' or 'hold-up'

• Provides very good lubricating properties

• It is recommended to use at room temperature

• There is built-in radiation protection

• With a strong 'adsorption' ability, it absorbs potentially harmful greases and chemical impurities on metal and glass surfaces

• Easy to clean and remove, easily wiped off with a soft, clean lint-free cloth that dissolves in hydrocarbons and chlorinated solvents

  Note: Since Apiezon hydrocarbon-based greases are insoluble in alcohol (B alcohol, isopropanol) or ketones (acetone, butanone), cause This cannot be cleaned with such substances.

Applications

1. It is often used for scientific and industrial sealing and lubrication

2. Manufacture and maintenance of high-performance Vacuum Pumps

3. For analytical techniques, such as infrared or mass spectrometry, which require avoiding contamination of the sample.

4. High radiation applications

5. It is often used as a stationary phase in gas chromatography analysis.

compatibility

1) Apiezon L-type grease can be used with a variety of O Ring materials are compatible, including:Fluoroelastomer, silicone, nitrile (> 30% nitrile content), nylon,polyurethane, polyethylene, polypropylene;

2) Apiezon L-type grease has a hydrocarbon matrix, so it is not compatible with the following substances: EPDM, ethylene propylene rubber, butyl rubber, PVC sealing ring.

Industry recognized

Apiezon L vacuum grease has beenRecognized by the European Space Agency, NASA, NATO and many other prestigious units.
