Dual Durometer Urethane Bars – Dual Duro Bars

Dual durometer urethane bars are produced at Plan Tech in two steps. Normally dual durometer urethane bars are cast of a hard base material with a softer outside coating. Dual durometer urethane bars are extremely popular in the paper cutting industry as cutter bars. These dual hardness urethane bars are essential in having a long service life in between sharpening the blades.

Urethane will absorb an impact and return to its original size even after years of repeat abuse. While most urethane bars are cast to a metal back dual durometer urethane bars is just another specialized part where urethane cannot be replaced by metal. There are many reasons why but we have found the biggest choice for dual durometer urethane is when there are chemicals that the material will be exposed to. Urethane does very well with most chemicals and does not break down easily. Cast from a hard durometer the base of dual durometer urethane bars may be tapped for bolt-on applications and is recommended for the use of threaded inserts. Plan Tech can rapidly replace worn out bars with no startup cost required. Each of the dual durometer urethane bars will be roughed up before a generous coat of bonding adhesive will be applied directly to each bar to ensure a bond to the material strength that is greater than the tear strength of the softer material.
