What is the function of the pad on a hold-down pipe clamp?

The pads that are bonded to the inside of the hold-down clamps along the radius may either be 3/32” thick PTFE, 25% glass filled slide plates or ¼” thick belting material. These pads allow for movement of the pipe within the hold-down clamp.
