Notes:
1
Two important laws of friction applicable to Bumpon products are: (1) Friction is independent of the area of contact between solids and (2) friction is
proportional to the load between solid surfaces. Thus, if the load (weight) is doubled the force required to cause sliding is also double. This is expressed
mathematically as follows: Sliding Force = Mk x weight.

These properties were run on sheet material from the same materials as the individual Bumpon products

Reference test for 24 hours. Results may vary for different product application conditions.
