Product ID : T25
T25 Apiezon T, Size=25 g. tube


Medium Temperature Vacuum Grease, Silicone Free

A rubbery nature, Grease T is designed for lubricating glass taps and for general purposes where operating temperatures necessitate the use of a relatively high melting point grease.

Grease T melts at 125 °C and has an estimated vapor pressure at 20 °C of 5 x 10-9 torr. Although Grease T is particularly useful at higher temperatures it can also be used at ambient temperatures and may be applied and used at temperatures between 0 and 120 °C.

(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.
