Nbr O Ring Chemical Resistance

O ring compatibility chart offers guidance on chemical resistance and swell for viton o rings ffkm o rings silicone o rings teflon o rings and more.

Nbr o ring chemical resistance. Use this rubber chemical resistance chart to make sure that the elastomer or o ring seal you choose will be compatible with the particular environment. The chemical compatibility of rubber is extremely important as the rubber can degrade rapidly if the rubber material is not compatible with the environment or media that it comes into contact with. All chemical resistance data for ethylene propylene epdm and fluorocarbon fkm contained within this manual has been provided with written consent by parker hannifin corporation. Buna n o rings also referred to as nbr o rings and nitrile o rings are the most widely used o ring material in the word because of low cost good mechanical performance with resistance to water most basic oils lubricants and some fuels many pneumatic hydraulic systems and the default choice for basic applications.

Resistance data was taken from parker s 2008 edition of the parker o ring handbook. Also called nbr or buna n nitrile o rings are probably the most economical and widely used elastomer out there. Choose compound from list to view o ring compatability rating. O ring compatibility plays a critical role in o ring performance â find the right material for your application and avoid o ring failures.

This material has a desirable set of properties including low compression set high resistance to abrasion and good tensile strength. The eriks o ring chemical resistance guide allows you to check some 20 different rubber families and some plastics against over 2000 chemicals. As the nbr content increases resistance to petroleum base oils and hydrocarbon fuels increases but low temperature flexibility decreases. About nbr due to its excellent resistance to petroleum products and its ability to be compounded for service over a temperature range of 35 c to 120 c 30 f to 250 f nitrile nbr is the most.

Fair good 40 o f good excellent 55 o f good 20 o f fair 110 o f steam resistance. Effective from 40 c to 120 c. Basic o ring chemical resistance compatibility information is based on isolated generic o ring material testing in optimal conditions at room temperature and pressure. The chemical compatibility of rubber is extremely important as the rubber can degrade rapidly if the rubber material is not compatible with the environment or media that it comes into contact with.

Buna n o rings buna n o rings. C severe effects except for some static.
