Wear-Indicating Elastomeric Sheet via Sublimation Ink Embedding

The patent applies color change technology by incorporating ink affinitive materials and ink repulsive materials in different ratios within the elastomeric composition. This creates regions that selectively absorb sublimation ink to different degrees, producing visible color differences that indicate wear patterns. The color-changing capability allows the product to maintain its protective properties while simultaneously providing visual feedback on wear conditions.

The patent changes the compositional parameters of the elastomeric material by varying the ratio of ink affinitive material to ink repulsive material in different regions. This parameter variation creates distinct ink absorption characteristics across the product surface, enabling differential color indication of wear. The compositional parameter changes are integrated into the manufacturing process itself, allowing the indicator function to be built into the product structure.

The patent applies local quality by creating regions with different ink affinitive material to ink repulsive material ratios in specific areas of the elastomeric product. This local compositional variation enables wear indication in high-wear zones while maintaining the overall simplicity of the elastomeric manufacturing process. The local quality changes are achieved through controlled material distribution during molding or mixing, integrating the indication function without fundamentally complicating the manufacturing approach.

The patent creates a composite elastomeric material system combining three components: base elastomeric material, ink affinitive material, and ink repulsive material. This composite approach allows the wear indication function to be integrated into the material itself rather than requiring separate indicator components. The composite material can be processed using standard elastomeric manufacturing techniques, maintaining ease of manufacture while adding the wear indication capability through material composition rather than structural complexity.
