Standard thermoplastic polyurethanes suffer from permanent discoloration when exposed to external contaminants. Reducing surface porosity or chemical affinity for dyes prevents irreversible aesthetic degradation.

Standard thermoplastic polyurethane beads and filaments lack the inherent chemical responsiveness required for high-definition marking and identification. Improving surface contrast allows for permanent traceability and aesthetic customization without compromising structural integrity.

Standard thermoplastic polyurethanes exhibit rapid combustion and dripping during fire exposure. Reducing this inherent fire risk is critical for safety compliance in structural and electronic applications.

Standard thermoplastic polyurethanes lose flexibility and impact resistance at sub-zero temperatures. Reducing the glass transition temperature prevents mechanical failure in cold environments.
