Tear Resistance Tester
Tear Resistance
The equipment is designed to directly read gF (TearForce) per one piece. The Tear Force thus obtained can be converted into Tear Energy, Tear Index or Tear Factor by applying appropriate formula.
Overview
In simpler terms tear resistance (or tear strength) is a measure of how well a material can withstand the effects of tearing. More specifically it is how well a material (normally rubber) resists the growth of any cuts when subjected to tension, it is usually measured in kN/m. Materials with low tear resistance tend to have poor resistance to abrasion and when subjected to force will quickly fail (this includes hard materials, since hardness is not related to tear resistance). The equipment is designed to directly read gF (TearForce) per one piece. The Tear Force thus obtained can be converted into Tear Energy, Tear Index or Tear Factor by applying appropriate formulae.
