| PHILAFIN™ rubber flexible cord jackets resist cracking to lower temperatures than either thermoset Neoprene or thermoset rubber. The following are results of bend tests: |
Ozone as generated around most electrical equipment can cause cracking in most conventional rubbers. PHILAFIN™ rubber has excellent resistance to cracking caused by ozone. Below are results of bent loop ozone aging tests of flexible cord jackets. |

| PHILAFIN™ rubber resists cracking and brittleness caused by heat far better than Neoprene or rubber. Comparative heat aging at 250°F. is shown. |
Shown below are comparative grinding wheel type abrasion test results on flexible cord jackets. Again, PHILAFIN™ rubber outperforms Neoprene and rubber flexible cord jackets. |

| 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: |
