Temperature range 

Apiezon T grease can be used over a wide range of temperatures from 10°C to 

120°C, while its optimum consistency is retained at temperatures of 25°C to 50°C. 

 

Silicone free 

As a hydrocarbon based grease, T grease is highly resistant to "creep" or “carry over”, a phenomenon associated with silicone-based products. Silicone has a tendency to travel away from the area of application and contaminate adjacent surfaces. 

 

Added cushioning 

A high molecular weight polymeric additive gives Apiezon T grease a tenacious consistency and provides extra cushioning between mated surfaces. 

 By absorbing vibrations in equipment Apiezon T grease is invaluable in fragile glass to glass joints which continually risk fracture. 

 

Sticking power 

Apiezon T grease is a very tenacious grease conferring excellent cohesive strength. Mated joints when joined together stay together, ensuring an efficient gas tight seal. 

 

Under vacuum 

At its higher operating temperature range, Apiezon T grease exhibits good vacuum properties in the lower to medium vacuum range, while at lower temperatures it can be used in the high vacuum range. Full information on the vapour pressure of Apiezon T grease is shown in the graph below. 

 

Easily removed 

Apiezon T grease is easily removed by wiping with a soft clean lint free cloth. Any residues of grease can be washed away with warm soapy water, by using any aromatic hydrocarbon solvent (toluene, xylene) or chlorinated hydrocarbons (trichloroethylene). 

 

Compatibility 

Apiezon T grease is compatible with a wide range of o-ring materials including:- 

- Viton 

- Silicone 

- Nitrile (>30% nitrile content) 

- Nylon 

- Polyurethane 

- Polyethylene 

- Polypropylene
