In one of our recent Bench Notes we talked about the different kinds of materials used on a saxophone and when to apply them. We now have another material to add to the list.
Sorbothane is our new synthetic polymer which we have mainly used as a silencing material on bell key bumpers. It also works well on key feet, especially on MKVI's, to eliminate the "bounce" that can happen when the key foot hits the body of the saxophone. Sorbothane is highly durable, non-porous, elastic, and absorbs vibration well. It is easy to cut and can be applied with contact cement or super glue.
This material was invented in 1982 and combines characteristics of rubber, silicone, and, according to a shoe manufacturer, human flesh. Sorbothane changes shape at the moment of impact, dispersing shock waves sideways. You will find this material very quiet and a great alternative to felt. Give it a try and let us know what you think!
