About This Product
Rubber parts such as seals and gaskets must spring back after being squeezed for a long time. A compression set test squeezes rubber specimens between plates for a set period, then measures how much thickness has been lost. A smaller loss means the rubber has kept more of its elasticity. The apparatus is used in rubber and polymer testing labs and in materials testing teaching.
Frequently Asked Questions
Q1. What does the Compression Set Apparatus measure?
It measures the ability of rubber compounds to retain elastic properties after prolonged action of a known compressive stress under static loading.
Q2. How is the test carried out?
A set of three circular test buttons is placed between rigid metallic plates and pressed under a force of 140 kg for 24 hours. The percentage reduction in thickness is then determined and compared against specified values.
