EPDM Rubber: Properties, Uses and Grades Explained
EPDM Rubber: Properties, Uses and Grades Explained EPDM rubber is a synthetic elastomer made from ethylene, propylene, and a diene monomer — most commonly ethylidene norbornene (ENB). The saturated polymer backbone produced by the ethylene-propylene chemistry gives EPDM its defining characteristic: outstanding resistance to ozone, UV radiation, weathering, steam, and hot water. It is the […]
Nitrile vs Viton Rubber: Which Seal Material Should You Specify?
Nitrile vs Viton Rubber: Which Seal Material Should You Specify? Nitrile (NBR) and Viton (FKM) are the two most widely specified elastomers for oil and chemical sealing applications — but they are not interchangeable, and choosing the wrong one is an expensive mistake. Nitrile is the standard choice for petroleum oil, hydraulic fluid, and fuel resistance up […]
Shore Hardness Explained: Which Rubber Hardness Do You Need?
Shore Hardness Explained: Which Rubber Hardness Do You Need? Shore hardness is a standardised measure of a rubber’s resistance to permanent indentation — expressed as a number from 0 to 100 on either the Shore A or Shore D scale. The higher the number, the harder the material. For rubber and elastomers, Shore A is […]
