What is Zero Yellowing Technology?
Caseco's "Zero-yellowing technology" is designed to prevent or delay the yellowing effect that often occurs in clear cases over time. Yellowing is typically caused by UV light, heat, skin oils, and environmental factors that degrade polymers, especially in cheaper TPU cases. Caseco addresses this with advanced treatments like UV-resistant coatings, high-quality polymers such as polycarbonate, anti-oxidation additives, and nano-coatings. These innovations work together to maintain the case's clarity, ensuring it stays clear and transparent much longer than traditional materials.
