Elastomers O-Rings and Seals

Elastomers, such as Nitrile (NBR), Hydrogenated NBR (H-NBR), Fluoroelastomer (FKM), Ethylene Propylene Diene Monomer (EPDM), and AFLAS, are highly flexible and elastic polymers that play a vital role in o-ring and seal applications. They provide reliable sealing performance even in the most challenging conditions.

Several essential factors are considered when assessing elastomer performance: temperature range, specific application, chemical compatibility, speed, and pressure.

These elastomers possess unique characteristics that make them ideal for uses involving o-rings and seals. Their natural elasticity and flexibility allow them to withstand significant pressure while returning to their original shape after compression. This remarkable quality ensures an effective seal that prevents leaks and promotes operational efficiency.

Moreover, elastomers are well-known for their ability to resist compression sets, maintaining their shape over extended periods. When considering elastomers, it is essential to evaluate tensile strength and elongation. A high tensile strength indicates excellent durability and resistance to tearing, while elongation reflects the material's ability to stretch without breaking.

Understanding the various types of elastomers, their key properties, and the factors affecting their performance will better equip you to choose the right material for your specific needs.
