AP101 Apiezon Grease AP101, Size=50 g. tube


Anti-Sieze Vacuum Grease, Silicone Free

Apiezon Grease AP 101 is a general purpose stop-cock grease suitable for moderate vacuum use with a very wide range of temperature from -40 degrees C to 180 °C. Vapor pressure is estimated to be 5 x 10-6 at 20 °C. The only grease in the range not manufactured by molecular distillation, AP 101 has nevertheless good vacuum properties. It is based on a heavy duty lubricating grease gelled with lithium stearate (a silicious earth) and PTFE.

(a)  Greases AP101 and H do not melt at high temperatures and consequently many of the above physical properties cannot readily be measured
(b)  Specific heats of Greases L, M, N and T cannot be measured as their fusion peaks are too close to room temperature.


PRECAUTIONS: Apiezon Products - Health and Safety

Apiezon products have been widely and safely used in vacuum distillation apparatus in both industry and laboratories for a number of years. As a result they should not present a health hazard assuming normal standards of industrial hygiene and safety are followed in their handling.

All Apiezon products are bases on petroleum products of a low order of acute toxicity. However, certain individual develop a rash after repeated contact. Therefore, it is recommended that gloves be worn to handle Apiezon. If Apiezon material is inadvertently in contact with the skin, wipe the area carefully, then cleanse thoroughly using a mild soap. Should any Apiezon products be heated for application, vent the fumes and avoid breathing the warm vapors.

In terms of explosion and fire, Apiezon products are considered non-hazardous.
