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:
Exhibit high tensile strength, making them the toughest of the elastomers. Compression set and heat resistance are inferior to other elastomers such as nitrile.
Material:
AU (Polyurethane)
Standard Service Temperature: -65°F - +212°F
Application:
Petroleum Fluids, Ozone, Abrasion Resistant, Drive Belts, Poor Compression Set
May be suitable for hydraulic applications which exhibit abrasive contaminants or shock loads.
*Polyurethane unlike other elastomers tend to revert or soften when exposed to over temperature situations).*
Not Compatible With: Hot Water, High Temperature, Brake Fluids, Acids
