50 Durometer vs 70 Durometer > Which do I choose?
Durometer is the measurement of HARDESS of neoprene.
50 Durometer pads handle loads up to 150 pounds per square inch (Most all home uses of the LP-13 Shake Absorber® pad will fall under this category. Washing Machines, Air Compressors, HVAC, and Lab Equipment)
70 Durometer pads are much denser and handle up to 400 pounds per square inch (Most industrial applications such as weaving looms and rock crushers will fall under this pads use. Typically, if your equipment weighs more than a ton this pad is used.)
