High Temperature Greases Types And Their Details
Right here are many requirements to take into consideration when picking a high-temperature oil for warm, grease-lubricated tools.
The selection must include consideration of oil type and viscosity, oil thickness index, thickener kind, stability of the structure developed by the oil as well as the thickener), additive composition as well as homes, ambient temperature level, operating temperature level, climatic contamination, loading, rate, relubrication intervals, etc
. With the selection of information to resolve, the selection of greases that must suit extreme temperature problems presents several of the extra tough lubrication design choices.
Given the range of alternatives, the possibility for incompatibility problems as well as high costs for a given high-temperature item, the lubrication designer need to be careful and also differentiating when sourcing items to satisfy high-temperature requirements.

Rocol HT70 Grease
Extremely high temperature bearing grease for slow speeds
ROCOL HT70 is a high molecular weight hydrocarbon polymer, containing molybdenum disulphide that evaporates slowly at high temperatures leaving minimal deposits. ROCOL HT70 is designed for the lubrication of slow speed plain and anti-friction bearings (less than 300 rpm) operating at high temperatures (over 180ºC) where normal greases leave heavy deposits causing blockages and jamming that can eventually lead to bearing failure.
Features and Benefits:
Excellent high temperature resistance – operating from +180°C to +300°C. ROCOL HT70 is designed for high temperature
· applications running under 300 rpm only. ROCOL HT70 gives negligible deposit formation
· thereby increasing component life. ROCOL HT70 evaporates slowly at high
· temperatures leaving a film of molybdenum disulphide which provides emergency protection if the HT70 is allowed to evaporate away completely before relubrication. ROCOL HT70 is a tenacious, pourable, fluid
· lubricant simplifying its application in the bottom bearings or rotary rack ovens.
Specifications:
HT70 does not contain: mineral hydrocarbons, animal derived materials, nut oils or genetically modified ingredients.

– Long-standing effective use at leading manufacturers of stenter frames
Your requirements – our solution
Due to increasing cost pressure, the textile industry is demanding chain lubricants offering ever higher thermal stability and longer relubrication intervals. We developed Klubertemp HCB 83-402 to reduce your operating costs. Klubertemp HCB 83-402 is a synthetic high-temperature lubricant for roller chains based on perfluorinated polyether oils and a new combination of PTFE solid lubricants. Klubertemp HCB 83-402 does not harden in continuous operation, extending machine availability. Relubrication of friction points is also made easier. Selected base oils provide the optimum combination of evaporation stability and the right viscosity for operation. The lubricant remains in the friction point for longer and increases the life expectancy of your roller chain. Klubertemp HCB 83-402 offers long relubrication intervals, reduced maintenance requirements and good wear protection to reduce your operating costs.
Application:
Klubertemp HCB 83-402 was specially developed for the longterm lubrication of rolling bearings in roller chains of highperformance stenter frames. The lifetime of the anti-spreader chain determines the performance and efficiency of your entire plant. Drying, conditioning and heat-setting may involve temperatures above 200 °C. Additionally, chain and lubricant are in contact with aggressive media from softening and finishing agents.
Under these conditions, Klubertemp HCB 83-402 has proven to be a durable and reliable lubricant. Klubertemp HCB 83-402 is generally regarded as neutral towards elastomers and plastics (with the possible exception of perfluorinated rubber). No negative effects are known when used with chain lubricants like Kluber PRIMIUM FLUID SPECIAL.

Mobiltemp SHC Series
Mobil temp SHC Series products are supreme performance antiwear greases primarily intended for high temperature applications. They combine the unique features of polyalphaolefin (PAO) synthetic base fluids with those of an organo-clay, non-soap thickener. The excellent resistance to thermal/oxidative degradation provided by the PAO base, coupled with the excellent high temperature structural stability and high dropping point of the clay thickener result in outstanding high temperature greases. The wax-free nature of the synthetic base fluid and its high viscosity index also provide superior low temperature lubrication as well as excellent film protection at high temperatures.
Because the PAO base oil has low traction properties (compared to mineral oil), Mobiltemp SHC Series also offer the potential for energy savings through reduced friction and lower torque, and reduced temperatures in the load zone of rolling element bearings. The Mobiltemp SHC Series is available as three products: Mobiltemp SHC 32 is an NLGI 1 1/2 grade with ISO VG 32 base oil; Mobiltemp SHC 100 is an NLGI 2 grade with ISO VG 100 base oil; Mobiltemp SHC 460 Special is an NLGI 1 grade with ISO VG 460 base oil, plus molybdenum disulphide for extra wear protection.
The Mobiltemp SHC Series of greases is used in numerous high temperature applications, as well as applications where low temperature start-up or running torque is important. They provide excellent grease life at high temperatures and offer extended relubrication periods and energy savings potential.
Mobiltemp SHC Series greases have become the products of choice for many users, in many industries worldwide. Their reputation is based on very wide application temperature range, and their excellent overall performance.
Features and Benefits:
The Mobil SHC brand of oils and greases are recognised and appreciated around the world for their innovation and outstanding performance. These molecular design PAO synthetic products, pioneered by ExxonMobil research scientists, symbolise the continuing commitment to using advanced technology to provide outstanding products. A key factor in the development of Mobiltemp SHC Series was the close contact between our scientists and application specialists with key Original Equipment Manufacturers (OEMs) to ensure that our product offerings would provide exceptional performance in the continually evolving industrial equipment designs.
Our work with equipment builders has helped confirm the results from our own laboratory tests showing the exceptional performance of the Mobiltemp SHC Series lubricants. These benefits include superb high temperature performance including thickener integrity and oxidation life with enhanced bearing protection and bearing life.
To combat high thermal exposure of the oil our product formulation scientists chose PAO synthetic base oils for Mobiltemp SHC Series oils because of their exceptional thermal/oxidative resistance potential. Our formulators used a special clay thickener to provide excellent structural stability and high dropping point. Mobiltemp SHC Series greases offer the following benefits:

ELRING Dirko Grey Silicone SEALANT
Dirko gray is a high-temperature sealing compound on a silicone base.
Dirko gray cures by reacting with the humidity in the air. The cured
sealing compound is permanently resilient. The product is characterized
by a very large range of applications.
Heat resistance:
The heat resistance of Dirko can be determined by simulating the extreme elongation behavior
of the sealing compound. Several key results of such tests are shown below. The elongation
simulated here does not occur in practice when used as a surface sealant.
Elastic modulus:
To determine the elastic modulus, the cured sealing compound is fixed in a clamping device
and is stretched 100%. The force required for this elongation is measured. The following
diagram shows the development of the elastic modulus (DIN 53504) as a function of the
pertinent temperature and time. The elastic modulus is shown as a percentage by comparison
to the value without temperature stress.

Victot REINZOSIL Gasket Maker
Material:
Anthracite coloured, solvent-free sealing, adhesive & coating compound
based on silicone. Once completely bonded, REINZOSIL is virtually
odorless
Properties:
This highly elastic universal sealing compound is resistant to mineral oils
and numerous synthetic oils, lubricants, petrol, diesel oil, greases, hot
and cold water, detergents, sunlight, ozone, and sea water.
REINZOSIL is suitable for continuous operation in the temperature
range between -50 °C and +250 °C (briefly up to 300 °C).
Hardness (softness) lies in the range of 30 to 35 Shore A.
Application:
Due to its special properties, REINZOSIL is used in the most varied
applications, e.g. as FIPG (formed-in-place gasket) for wet assembly, i.e.
for sealing small gaps under pressure as well as for cylinder liners in
piston machines, and also to compensate for extensive component
warping. Moreover, the compound is also used to seal constructional
fissures or cracks, and for seals that are subjected to considerable
relative movement.
Contrary to REINZOPLAST, the sealing layer is destroyed during
disassembly, and a new coating is required after the surfaces have been
cleaned.
The compound can also be applied to assembled components. In these
cases, after the sealing joint has been cleaned and degreased,
REINZOSIL is applied directly to the sealing gap, similar to the
procedures used in the building industry.
Storage period:
Unopened cartridges can be stored for about 12 months in a dry
environment (+5 °C up to 25 °C).
