SAE AMS-R-6130

Description / Abstract: Type I (open cell): Chemically blown cellular rubber is intended for use in shock absorbing cushions for mounting radio apparatus, in crash pads, and other miscellaneous uses requiring a material capable of absorbing shock and damping vibrations. It is not recommended for applications involving tensile loading, or where the cellular chemically blown rubber will come in continuous contact with the human skin.

Type II (closed cell): Type II material is intended for flotation gear (skin or rind form only) expansion joint fillers, gaskets, and shock pads where water repellent qualities are desired. It is not recommended for applications where extreme high temperatures are encountered, or where the expansion of the material at high altitudes will be a disadvantage.

Grade: The intended use for grades of Type I (open cell) and for Type II (closed cell) are as follows:

a. Grade A: Grade A cellular rubber is intended for use where resistance to oil and flame is required.

b. Grade B: Grade B cellular rubber is intended for use where resistance to oil is not required.

c. Grade C: Grade C cellular rubber is intended for use where lower-temperature resistance, but not oil resistance, is required.
