Triangle Touts New OTR Tire Bonding Technology

A new-generation bonding and protection technology has been developed by Triangle Tire for giant OTR tires.

Triangle Tire's new "EnsureX Efficient Technology resolves the long-standing industry challenge of adhesion ... between rubber polymers and steel cords in heavy-duty OTR tires," according to Triangle officials.

"With this technology, which was three years in development by the Triangle R&D team, delamination failures in the new generation of giant OTR tires (from Triangle) are reduced by more than 95%, while tire service life is extended by over 15%. The innovative technology - an ultra-high-performance cobalt-free formulation combined with a coordinated coated steel-cord adhesion system - is built around a high-performance cobalt-free bonding system and gradient adhesion-layer distribution technology." Features and benefits include:

"Outstanding fatigue resistance. By developing an advanced bonding formulation and a flexible multi-alloy coating that generates stronger adhesion, the system accommodates the high-frequency deformation demands of giant OTR tires under heavy loads;"

Enhanced aging resistance. "Improved 'dynamic toughness' and anti-aging performance at the interface ensure a 'uniform and dense' bonding structure, increasing adhesion strength by more than 40% and safeguarding structural integrity throughout the tire’s entire lifecycle;"

Long-lasting corrosion protection ... "making it well-suited for harsh tropical and coastal environments and significantly improving tire service life, safety and retreadability," according to Triangle officials.
