TR90 - Swiss EMS Gasoline-Resistant Nylon material exhibits high toughness with a deformation resistance index of 620 kg/cm², and impact resistance more than twice that of ordinary nylon. It complies with ISO 180/IC safety standards, reducing the risk of eye injuries during sports activities. The material withstands high temperatures up to 350°C, is not easily combustible or meltable in short periods, and releases no chemical residues, meeting European food-grade standards. The finished product features a smooth surface and diverse colors, though complex manufacturing processes result in higher costs. Market-derived materials such as TR100 and TR120 are based on TR90, with minor differences in performance and price, commonly used in sports glasses and blue light-blocking frames;
