Standard Test Methods for Rubber Properites in Compression



Rubber is a type of elastomer that exists above its glass transition temperature while at normal room conditions. Rubbers are therefore relatively easy to deform which makes them perfect for applications where the material must be flexible. Rubbers are seen most often in the automotive industry for hoses, seals, and tires. The 2015 global market for elastomers is estimated at between $40-50B. 


The compressive properties of rubber are tested using compression platens. Sandpaper may be used in between the platens and the sample in order to reduce the occurance of slippage. For this test, the rubber sample is compressed to a pre-specified deflection percentage.


The platens must be larger than the sample and also must be rigidily fixed. The standard clevis pin and jam nut mechanism is sufficient to lock the platens. A deflectomer may be attached directly to the platens for high precision testing.
