79-25 Bending Resistance Tester

TMI Bending Resistance Tester & Optional GraphMaster™ Software

INTRODUCTION

Model 79-25 is a user-friendly microprocessor controlled instrument to determine the bending resistance of paper, paperboard, plastic film, medical tubing, and wire. Bending stiffness is a characteristic associated with the rigidity of a material. This property is related to the modulus of elasticity of the material's stiffness. Our Bending Tester was originally developed to produce a more concise, consistent measurement for the paper industry. This property is now used in a variety of industries including personal products, paper, flexible films, packaging and non-wovens.

Our two-point method secures the specimen into a pneumatic clamp and bends the sample up to 90° against a force transducer.

What makes our Bending Resistance instrument so unique is its versatility and accuracy. Bending forces are measured at selectable bending angles from 5.0 to 90°. The instrument is available with a 100 or 1000 gram precision load cell. The advanced data acquisition system senses forces down to 0.5g. Materials can range from 5 to 50mm in length, up to 2.5mm thick.
