Problem: Breakdown in fridged temperatures
Extreme cold temperatures may cause flatproofing to freeze and disable vehicle.
Solution: Extensively test Arnco’s flatproofing for cold weather applications
The University of Alaska tested both SuperFlex and RePneu in temperatures of -40F / -40C. ASTM D2136 and ASTM D2137 brittleness tests were performed after allowing test product to sit for 16 hours with no signs of fracture or cracking.
 Test product could easily be bent, twisted,
and otherwise distorted, and showed no signs of degradation.
Durometers tended to increase substantially, but reverted back
to their original and designed parameters after they were allowed
to warm, or were put into service.
