Hardness Rating of Gap Pad(Gap Filler)
Q: Why does the data sheet describe the hardness rating
as a bulk rubber hardness?
A: A reinforcement carrier is generally utilized in Bergquist Gap Pads
for ease of handling. When testing hardness, the reinforcement
carrier can alter the test results and incorrectly depict thinner
materials as being harder. To eliminate this error, a 250 mil rub-
ber puck is molded with no reinforcement carrier. The puck is
then tested for hardness. The Shore hardness is recorded after a
30 second delay
