De Mattia Flex Tester For Testing Lab Description and Specifications for Lab Tenders
De Mattia Flex Tester For Testing Lab Workshop.
De Mattia Flex Tester -
The ability of rubber products to withstand repeated flexing without
developing cracks is of prime importance where such products are used in
conditions undergoing repeated flexing.
Flexing endurance of
rubber products is determined by simulating in laboratory the action of
flexing repeatedly under standard conditions of speed, mode, and degree
of flexing.
One of the accepted procedures for determination of flexing resistance makes use of a De Mattia Flex Test.
This test provides useful information about the resistance of compounds
of vulcanized rubber to flex cracking when subjected to flexing. Cracks
develop in that part of the surface where stresses are set up during
flexing, or if that part of the surface initially contains a crack,
cause this crack to extend in a direction perpendicular to the stress.
