SUPERIOR MECHANICAL STRENGTH

LIGHTER WEIGHT
One measure of the
mechanical strength of a flexible cord is
resistance to failure under a crushing load. Below are results of
crushing strength tests for flexible cords.
Another important
consideration in "portable" power supply
cordage is weight. PHILAFIN can offer a lighter, more portable
cable than either rubber or Neoprene. Typical weight savings on
12/3 cords are shown as follows:
