To understand the durability of rubber compound, HASETRI offers prediction of Crack nucleation and crack growth rate at different operating condition.
Fatigue crack growth (FCG) behaviour of elastomer compounds is an essential criterion to understand the cause of failure. As most of elastomer product undergoes millions of fatigue cycles during their service life, one micro-crack can leads to an ultimate failure if FCG characteristic of that compound is not sufficient enough to restrict the propagation. There are various factors which influence the FCG characteristics of rubber vulcanizates viz. temperature, strain rate, type of elastomer and filler etc.
It is possible to measure FCG at different environmental conditions:
To understand the topography and morphological characteristics of the compound, HASETRI offers Optical and Scanning Electron Microscopic (SEM) analysis for different Samples including sectioning of the thin specimen (100 nm) by Ultramicrotomy.
Microscopic analysis of any substance is important to understand the several phenomenons such as: dispersion behaviour of fillers, topography of fracture surface, root cause analysis of failure etc. To understand the chemical composition of any material, we characterise them through Energy Dispersive Spectra (EDS) also where mapping of individual element (Such as Zn, Sulphur and Silica etc.) can be done via point or line scan mode.
IHASETRI can offer to analyse materials with different modes:
