What is high vacuum silicone grease?
Dow Corning® High Vacuum Grease is a silicone-based, odorless, translucent white-grey grease suitable for use in sealing and lubricating. A stiff, non-melting silicone material, Dow Corning High Vacuum Grease seals and lubricates valves, bearings, gaskets, O-rings, and vacuum and pressure systems.
What is apiezon grease?
Apiezon L Grease is a silicone and halogen-free ultra-high vacuum grease suitable for use scientific and industrial applications. Apiezon L Grease has the best vapour pressure properties of all the Apiezon products and is therefore suitable for use in ultra-high vacuum applications.
When should I use vacuum grease?
As well as a lubricant, vacuum grease is also used as a sealant for joints in vacuum systems. This is usually limited to soft vacuums, as ultra high vacuum or high temperatures may give problems with the grease outgassing. Grease is most commonly used with glass vacuum systems.
Is vacuum grease the same as silicone grease?
No, the difference in the components makes greases differ from one another. There are hydrocarbon greases as well as silicone greases.
What is silicone grease made of?
Silicone grease is a type of viscous lubricant that is made with a combination of silicone oil and an inert filler, such as silica powder and thickeners such as lithium soap. The grease is generally a thick, white paste.
What is high temp grease?
WD-40 Specialist® High-Temp Grease is a lithium-based grease built to perform in high temperatures and high-friction mechanical loads. It was engineered to meet the demands of protecting high-speed bearings in applications involving high temperatures and heavy mechanical loads.
Who makes krytox?
The Chemours Company
Krytox is a registered trademark of The Chemours Company. It refers to a group of colourless synthetic lubricants (oils and greases) with a variety of applications.
Which of the following lubricant can be used in a high vacuum?
Tungsten Disulfide
It has a coefficient of friction of 0.03 and offers excellent dry lubricity under conditions of load, vacuum and temperature. It can also be used in high temperature and high-pressure applications.
Is Dow Corning high vacuum grease food grade?
Vacuum Grease is not “Food Grade” for THC/CBD Distillates.
When should you not use silicone grease?
Silicone oils are dielectric and so is silicone grease, silicone is generally low cost and widely available. However we do not recommend using any silicone based lubricant for use on electrical connectors or contacts.
What’s the difference between silicone and silicone grease?
Silicone greases are often considered to be the same as silicone pastes. Whereas silicone greases are thickened with a lithium soap, silicone pastes are made by dispersing silica in PDMS (Polydimethylsiloxane) oils with the use of thickening agents.
Is white lithium grease high temp?
White Lithium Grease is also water-resistant, highly tolerant to extreme pressures, and boasts a working temperature range that extends from –25Cº right up to 130Cº.
Where do you use high temp grease?
High temperature greases are particularly suitable for lubrication of elements such as:
- roller bearings operating under severe conditions.
- rolling mill bearings.
- oven fan bearings.
- glueing machine roller bearings.
- hot-mix asphalt stations.
- crushing and screening equipment.
- oven racks and furnace hearth rollers.
- …
Why is Krytox expensive?
Krytox has a giant MOQ, so it can get up there in price for people who stock it (plus distribution rights).
What is similar to Krytox?
Other great alternatives!
Super Lube’s synthetic oil is a nice alternative to Krytox GPL 105. Super Lube’s Grease is also an alternative to Krytox 205g0, although a bit thinner than the 205. Both of these alternatives can often be found for cheap, if available.
Can you use Super Lube as dielectric grease?
Can Super Lube® be used as a dielectric grease? Yes, Super Lube® Greases and Oils have good electrical insulating properties and will protect electrical and electronic equipment.
Is vacuum grease flammable?
Suitable extinguishing media the product is not flammable. Extinguish with alcohol-resistant foam, carbon dioxide, dry powder or water fog. Use fire-extinguishing media suitable for the surrounding fire. Special hazards arising from the substance or mixture Specific hazards None known.
Which is better silicone or lithium grease?
As mentioned above, and unlike lithium grease, silicone lubricant is the perfect lubricant for rubber surfaces, but it is also extremely versatile, so it can be used on most other materials, including metal, plastic, wood, and even painted materials.
Should O-rings be lubricated?
Lubrication of O-rings is essential for the proper function and full-service life of the seal, but also to ensure the machine, motor, engine, or device in which it is placed does not malfunction from a blown seal. A grease or oil application at assembly helps to protect the O-ring from damage during use.
What should you not use silicone grease on?
Because it is so slippery and persistent, avoid using silicone spray under the following conditions:
- DO NOT USE SILICONE SPRAY ON ELECTRICAL CONNECTIONS, SWITCHES, RELAYS, ETC.
- On any surface upon which you walk, sit, or lay.
Where should you not use lithium grease?
A trait of grease is that it has a high level of gooeyness when used on surfaces. Lithium-based lubricants are used in cars and machinery in general. It’s not advisable to use them on plastic parts. As lithium is based on petroleum, it tends to speed up rubber and plastic components decay.
What is considered high temp grease?
For the sake of reference, generally an oil that is able to work at temperatures higher than 210-250 degrees F (100-120 degrees C) for a normal or extended drain interval may be assumed to be a high-temperature lubricant.
Is High Temp grease good for bearings?
At these extreme temperatures, the oil can run out of the bearing leaving only the thickener behind. This leaves the bearing with inadequate lubrication. A high temperature grease does a better job of preventing oil separation at higher temperatures. This type of grease is a better choice for bearings that run hot.
Can Krytox dry out?
“Krytox™ products solve this problem because it doesn’t dry out, it doesn’t degrade, and it stays put for the life of the vehicle,” French explains. “Apply it once, and it’s good.”
