AGE CONTROL OF AGE SENSITIVE ELASTOMERIC MATERIALS

1975-05-01
HISTORICAL
AIR1364
This report summarizes data and background relative to age control of specific classes of those nitrile type synthetic elastomers used in sealing devices which are resistant to petroleum base hydraulic fluids, lubricating oils and aircraft fuels. This includes, but is not limited to, those nitrile (NBR or BUNA-N) elastomers specifically covered by Section I of MIL-STD-1523.

Butadiene - Acrylonitrile (Nbr) Rubber for Fuel-Resistant Seals, 60 to 70

2018-04-15
WIP
AMSP5315C
This specification covers a butadiene - acrylonitrile (NBR) rubber in the manufacturer of molded seals.

These products have been used typically at temperatures from -65 degrees F (-54 degrees C) to +180 degrees F (+182 degrees C) where resistance to fuel is required, but usage is not limited to such applications. Each application should be considered individually.

Ethylene Propylene (EPM) Rubber, Phosphate Ester Resistant, 55-65

2019-05-07
WIP
AMS3248D
This specification covers an ethylene propylene (EPM) rubber in the form of sheet, strip, tubing, molded shapes, and extrusions. Primarily for parts, such as gaskets, grommets, and seals requiring resistance to phosphate esters and/or to ozone. Not suitable for use in contact with petroleum base fluids due to excessive swell.
