Shore A Description:

The hardness of rubber compounds is measured by the Shore A durometer; the higher the durometer, the harder the compound. Softer compounds stretch easier and seal better on rough surfaces. Harder compounds offer greater abrasion resistance and resistance to extrusion.

60 Shore A is softer than 70

70 Shore A is the standard

90 Short A is very stiff


Specs:

Polymers vary from 18% to 50% acrylonitrile content. Resistance to petroleum products increases as acrylonitrile increases; conversely, low temperature flexibility decreases.


Material:

NBR (Natural Rubber)

Standard Service Temperature: -40°F - +250°F


Application:

Petroleum Fluids, Water (to 212°F), Silicon fluids, Ethylene Glycol, General Purpose

Nitrile compounds can exhibit excellent compression set, tear and abrasion resistance.


Not Compatible With: Phosphate esters, Ketones, Brake Fluids Strong acids, Ozone or weathering.
