Tyre and Fatigue Analyser (TFA)

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. Under cyclic loading condition one micro-crack can lead to an ultimate failure of the product 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:

High Temperature (Max 150oC)
Low Temperature (Min -50oC)
Inert (Nitrogen), Oxygen and Ozone atmosphere

Different loading conditions:

Variable Strain
Waveforms (Sine, Pulse etc.)
Variable Frequency
Non-relaxing load (R-Ratio)

Highlights

HASETRI featured in Indian/International Rubber Journal

An enlightening interview with Dr. R. Mukhopadhyay, Director & CE, HASETRI, speaks of the current situation of the Indian tire and rubber industry and how they are coping with the pandemic.

HASETRI successfully enhanced the scope of NABL accreditation

September 2021: HASETRI has successfully enhanced the scope of NABL accreditation in Wet Grip and Coast by Noise testing for Cl & C2 category tyres as per ECE R117 and proposed AIS 142.
