Arctic/Tropic cords are made of oil resistant TPE-Rubber (SJEOW) which provides maximum flexibility year-round. Cords retain strength in temperatures as high as 212°F and flexibility in temperatures as low as -58°F. Superior resistance to sunlight, ozone, cracking, and chemicals, makes it great for use in garages and industrial applications where extra protection is needed. Yellow jacket color is a highly visible safety color for work sites.
