The Making of
BEHN™ Proprietary

Rod Rubber

Click through the slide show to see the process.

Natural rubber is mixed with sulfur and other ingredients to produce a doughy like compound. This material is rolled into rod shaped links and then placed into our mold. The mold is placed into a press where heat and pressure are applied for a long cure cycle. The resulting rods are then CNC-machined into mouthpieces.

​

Behn™ Proprietary Rod Rubber is used in all EPIC™ clarinet mouthpieces. To learn about the inspiration behind this unique rubber formulation, please read "The 'EPIC' Story: Bringing 1920s 'Golden Era' Henri Chedeville Mouthpieces Back!"
