Rubbers are a class of materials that serves a great deal of engineering
needs in fields
dealing with shock, noise and vibration control, sealing, corrosion
protection, friction production,
waterproofing, thermal insulation, etc.
ASTM D 1418 - Rubber and rubber Lattices describes all available rubbers
in terms of their chemical
compositions. Additional data is available per ASTM D 2000/SAE J200
Below please find some data with regards to the Physical and Mechanical
properties for natural rubber and
Density (gm/cucm) = .93
Hardness range (Shore A) = 30-100
Tensile Strength (max. psi) = 4,500
Density(gm/cucm) = 1.24
Hardness range(Shore A) = 40-95
Tensile Strength(max. psi) = 4,000
Please note that Neoprenes do not have the low-temperature flexibility of
natural rubber, which detracts from
their use in shock or impact applications.
Hope this helps.
