Bronco 2000 -- Type SEO. When compared to
Neoprene and rubber, Bronco 2000™
insulation provides better: |
 |
| · Oil Resistance |
| · Low Temperature Resistance |
| · Heat Aging |
| · Ozone Resistance |
|
| · Chemical Resistance |
| · Abrasion Resistance |
| · Mechanical Strength |
| · Lighter Weight |

LOWER TEMPERATURE FLEXIBILITY
Bronco 2000™ rubber flexible cord jackets resist cracking to
lower temperature than either Neoprene or rubber. The following are results of bend tests: |
GREATER OZONE RESISTANCE
Ozone as generated around most electrical equipment can cause cracking
in most conventional ruibbers. Bronco 2000™ rubber has excellent resistance to cracking caused by ozone. Below are results of
bent loop ozone aging tests of flexible cord jackets. |

SUPERIOR HEAT AGING
Bronco 2000™ rubber
resists cracking and brittleness caused by heat far better than Neoprene or rubber.
Comparative heat aging at 250°F is shown.OVEN AGED 7 DAYS @250 F |
TOUGHER ABRASION RESISTANCE
Shown below are comparative grinding wheel type abrasion test resutls on flexible cord
jackets. Again, Bronco 2000™ rubber outperforms neoprene and
rubber flexible cord jackets.CYCLES TO FAILURE |

SUPERIOR MECHANICAL STRENGTH
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. |
LIGHTER WEIGHT
Another important consideration in "portable" power
supply cordage is weight. Bronco 2000™ can offer
a lighter, more portable cable than either rubber or Neoprene. Typical weight savings on
12/3 cords are shown as follow: |
