Lithium-based greases are the most commonly used; sodium and lithium-based greases have higher melting point (dropping point) than calcium-based greases but are not resistant to the action of water. Lithium-based grease has a dropping point at 190 to 220 °C (
350 to 400 °F
).
What is the boiling point of grease?
Lubricating oils are complex mixtures containing linear and branched paraffins, cyclic alkanes, and aromatic hydrocarbons (> C
15
with boiling points
between 300 and 600 °C
) (Vazquez-Duhalt, 1989).
What is high melting point grease?
Extremely high melting point,
lithium complex grease
, designed for use in anti-friction bearings operating in high temperature conditions. … High Temp Grease offers good resistance to water and corrosion, along with very good load carrying performance.
What temperature does grease breakdown?
The mineral oil in grease can flash, burn, or evaporate at temperatures above 177 EC (350F). High temperatures,
above 73-79C (165-175F)
, can dehydrate certain greases such as calcium soap grease and cause structural breakdown.
What is the highest temp grease?
DSF-5000
®
is a “Technically Advanced” synthetic grease designed for use on equipment where constant operating temperatures can reach 1500° F / 815° C, and even higher intermittently.
Can Vaseline be used as grease?
Vaseline: you
can use vaseline for all sorts of applications
. It is a great lubricant for metal parts such as the air installation, but it is also regularly used for installing PVC parts. Note: contrary to ball bearer grease, vaseline does become liquid at higher temperatures (40 – 60°C), causing it to drip.
Is grease toxic to humans?
Eye: May cause mild irritation. Skin: Prolonged contact may cause irritation and drying of the skin. Inhalation:
No adverse effects expected at ambient temperatures
. Inhalation of vapors and fumes from thermal decomposition may cause respiratory irritation and metal fume fever with symptoms of fever and chills.
Where do you use high temp grease?
Very high temperature greases are particularly suitable for lubrication of elements such as:
Oven fan bearings
.
Bearings for pre-heater rollers
.
Conveyors, industrial painting lines
.
Is lithium grease high temperature grease?
HEAT RESISTANCE: Lithium grease demonstrates excellent heat resistance. It is capable of
withstanding very high temperatures
and has a drip temperature of approximately 200° Celsius. This is another favourable characteristic when it comes to the auto industry.
What type of grease thickener is more resistant to high temperature?
Lithium complex-thickened grease
has maximum temperature limits superior to that of simple lithium grease, because the thickener offers higher thermal degradation limits. Collectively, metal soap thickeners have thermal degradation limits that range between 250oF to 430oF (120oC and 220oC).
How do you liquify grease?
Another method of dissolving stubborn kitchen grease is to use
isopropyl alcohol
. Isopropyl alcohol works in a similar manner to water-displacing lubricants. It breaks up the grease into smaller particles and surrounds it with alcohol molecules, in effect dissolving the grease.
Is WD 40 heat resistant?
WD-40® SPECIALIST® HEAVY-DUTY HIGH TEMPERATURE GREASE was engineered to meet the demands of protecting high-speed bearings in applications involving high temperatures and heavy mechanical loads. Able
to resist melting up to 625° F
, it’s also excellent in cold weather.
What happens to grease when it gets too hot?
Hot oil
shortens the life of filters and seals and accelerates corrosion
. Both oil and grease are more prone to leakage. Grease separates fasters (oil from thickener) at elevated temperatures. High surface temperatures can form carbonaceous gum and resins.
What kind of grease is used for brake pads?
Super Lube® Silicone Lubricating Brake Grease
can also be used to dampen vibrations between disc brake pads and caliper pistons. It should NOT be applied between the pads and any noise suppression shims. Use it sparingly on the back of a bare pad or between the pad shim and caliper.
Can I use high temp grease on brakes?
Use new high-temperature grease to improve long-term brake performance and wear. Improve brake performance and extend wear by using new high temperature grease to lubricate the moving parts. It dissipates heat better and won’t degrade as rapidly.
Is white lithium grease high temp?
Permatex White Lithium Grease
Stainless and long-lasting formula. Contains no ODCs.
Withstands moisture and high temperature
.
