WHITE PAPER
Engineering Insight into Material Performance
Technical studies from Karax exploring material aging, degradation mechanisms, and physics-anchored approaches to service-life prediction.
How accurately can accelerated aging reveal the long-term performance of PU waterproofing?
ElastoSure evaluates three independent aging mechanisms—thermo-oxidative, hygrothermal, and acid exposure—to predict long-term service life from accelerated-aging data.

Predicting Thermal & Hygrothermal Aging in Polyurethane Adhesives
How can an adhesive become stronger while losing critical performance?
ElastoSure evaluates thermal and hygrothermal aging in a 1K-PU structural adhesive, showing how strength can remain stable or increase while fracture strain and post-yield energy dissipation decline.

HNBR After Extreme High-Temperature
High-Pressure Oil-Mud Aging
What happens to HNBR seals when exposed to 175°C and 70 MPa?
After just 72 hours, HNBR lost 81.5% of its fatigue life and 70.3% of its elongation, while tensile strength dropped only 6.4%.
This study reconstructs material behavior and explores future-aging scenarios to assess degradation and guide further testing.

FR3-Immersed Polymers: Measured Aging and Illustrative Forecasts
What happens when seven engineering polymers are aged in natural ester transformer fluid at 170°C?
Cargill's TR-610 report shows 30% glass-filled PBT losing nearly 40% of its tensile strength after 2,000 hours in FR3 ester fluid, while PPA retained slightly more than its original strength under the same exposure.
This benchmark fits a transparent two-point analytic curve to the measured endpoints across 13 property series and illustrates sample aging-time values beyond the tested range to guide where independent validation testing should focus next.
