H-25G

Vacuum grease

H-25G high temperature Vacuum grease is silicone-free vacuum grease, can be called vacuum sealing grease, Operating temperature range is -10~240 ℃, Apiezon H high temperature Vacuum grease vapor pressure is 1.7x10 ^ (-9) Torr.

Introduction

Apiezon H High Temperature Vacuum Grease is a silicone-free high vacuum grease with an applicable working temperature of -10~240°C, which is particularly suitable for scientific and industrial use at high temperatures. H grease has a special "adhesion" and heat conductive properties that are highly recognized by various international organizations, including BAE Systems, the European Space Agency and NASA.

Features

1) It performs well in the temperature range of -10°C~+240°C and maintains good consistency between +10 and +110°C

2) It does not melt, but becomes stiffer as the temperature increases, so it is not recommended for high-stress bearings

3) It has excellent thermal conductivity

4) Heat conduction leaves the operating place to reduce the risk of overheating and damage to heat-sensitive components

5) Exhibits good "adhesion" or sticking power

6) It has a strong 'adsorption' ability, it absorbs potentially harmful greases and chemical impurities on metal and glass surfaces.

7) Easy to clean and remove, soluble in hydrocarbons and chlorinated solvents

8) The vapor pressure displayed at 20°C is 1.7 x 10-9 Torr

Applications

1. It is often used in scientific and industrial high-temperature sealing applications, as well as heat transfer applications.

2. It is a satisfactory choice for laboratory glass products, and because of its high thermal conductivity, it makes it a good vacuum grease when the radiator medium needs adhesion, and is also favored by the electronics and aerospace industries.

3. It is suitable for use as a lubricating material for the gold-plated wire of small variable capacitors under the condition of temperature from -65°C to +125°C under high vacuum to avoid wear.

Note: Apiezon HHigh temperature vacuum greaseRelatively thick, does not melt, but It will thicken as the temperature rises, and it will not be pushed in high temperatures It is recommended for use as a lubricant.

Industry recognized

◆ Apiezon H has a wide range of uses in many industries, and has been recognized by British Airways, the European Space Agency, Matera Marconi Space and NASA.

◆ Approved by NASA, Apiezon H grease is the suitable material for small transformer gold plated wires operating between -65°C and +125°C under high vacuum to avoid chafing.

compatibility

1. Apiezon H is compatible with a variety of O-ring materials, including: fluoroelastomer, silicon, nitrile (> 30% nitrile content), nylon, polyurethane, polyethylene, polypropylene;

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

Shelf life

Apiezon H grease has a shelf life of 10 years from the date of manufacture when stored unopened in its original packaging and stored at ambient temperature.
