BioThane's strength is determined by the material's width and not its thickness profile (2mm vs 4mm). Here is a list of BioThane-tested break strengths for the widths we stock:

  • 1/2 inch (500lbs)
  • 5/8 inch (625lbs)
  • 3/4 inch (750lbs)
  • 1 inch (1000lbs)
  • 1.5 inch (1500lbs)
  • 2 inch (2000lbs)
These numbers are impressive, but it is important to remember that your leash or collar will only be as strong as its weakest point. This is most commonly the hardware/snap or the connection points where two different pieces of material are joined together. For this reason, we stock the highest quality hardware we can find.
