K-Extreme predicts polymer survivability under extreme HPHT conditions, while K-Load models long-term seal life under combined HPHT, fatigue, and fluid exposure—replacing months of physical testing with simulation.

What Is HPHT Polymer & Elastomer Survivability?
Composite aging begins at the microstructural scale. The polymer matrix degrades, the fiber-matrix interface weakens, and damage accumulates across the laminate through micro-cracks and delamination.
Traditional fatigue tests provide design allowables, but not how those values change over years of moisture, thermal cycling, and real-world loading. ElastoSure models that degradation over the structure’s service life.
Moisture is a major driver. Water plasticizes the resin, lowers glass transition temperature (Tg), and weakens the fiber-matrix interface. Combined with thermal cycling and fatigue, these effects become synergistic—not simply additive.
