3M™ VHB™ Tape 4950 White, 1 in x 36 yd 45.0 mil

        I just ordered some more of these ( one each ) - 3M VHB tapes "Very High Bond" one in white and one in black that has the same specs but is $30 more. Mostly to see what the difference is between the 2 tapes. Stay tuned and I will update you how it turns out. YOU ASK WHAT ARE THESE USED FOR ? Well the answer is simple, its a foam tape that sticks 2 parts together almost like super glue...., example in cargo trailers metal side panels are screwed every 6" - this tape allows the trailer to have a screw-less exterior, much cleaner & stronger looking, allows for metal expansion without creating wrinkles. you can use this to glue solar panels to the metal trailer roof.

Well the mystery was solved by Mary, mostly because the Black tape was not in stock.

               In answer to your question, 3M set's list pricing and we base our discount pricing on this. The black is normally around 10-15% more. In this particular instance, it's the theory of supply and demand. We buy the white (4950) in bulk quantities and are able to pass that savings along because we sell more of this product. The black (4949) is not as popular so we buy smaller quantities and pay an up charge for those so that we are sure to provide our customers with product within the shelf life. 

Below take a look at the data of how strong this tape really is
look at the bottom 2 lines, it will take a force of 25lbs to remove 1" squared of tape
140 lbs per sq inch for Normal Tensile & 80 lbs per sq inch Dynamic Overlay Shear
Now you know why its so damn expensive
