CS 3000

Compression Set Test Fixture

The CS 3000 is the rubber industry’s most durable compression set fixture for silicone, rubber, natural rubber and any elastomeric compound.

The compression set test for rubber or other elastomeric materials is one part of calculating resiliency loss, or memory permanent set, of a cured compound. Made of precision ground stainless steel, the MonTech CS 3000 compression test fixture is available in multiple sizes according to all ASTM, ISO and DIN test methods. It is recommended that rubber aging ovens (AO 3000) and thickness gauges (TGD 3000) are also used for this test.

CS 3000

Compression Set in Oven

As a rubber sample is compressed over time between two flat parallel plates with predefined percentage and kept for a specific time at a certain temperature, it loses its ability to return to its original thickness. This loss of resiliency, also called memory or permanent set, characterizes the capability of an elastomeric product to perform over a long period of time.
