CORD 7.1MM NBR70
9/32" CORD NBR70
- NBR (Natural Rubber)
- Standard Service Temperature: -40°F - +250°F
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
Polymers vary from 18% to 50% acrylonitrile content. Resistance to petroleum products increases as acrylonitrile increases; conversely, low temperature flexibility decreases.
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.
