Paintable PC

Background of Paintable PC Development

As phones moved from feature phones to smartphones and from plastic to metal housings, and metal housings entered the ultra-thin era, demand for ultra-thin phone cases surged. Strong market demand drove product diversity, and ultra-thin phone cases became a focus for manufacturers and users alike. Users want thinner, lighter cases, and ultra-thin protective cases, with their slim, attractive look and protective performance, are naturally popular with consumers.

　　

Thanks to its excellent transparency and feel, PC is widely used to make ultra-thin phone cases. In production, however, many manufacturers face the same problem: ultra-thin PC cases tend to crack after painting, and the material becomes brittle. Various fixes, such as adjusting paint thinner concentration or baking time, solve some minor issues, but none fully eliminate cracking, and yields remain very low. In response to this market need, we developed a paintable PC for ultra-thin phone cases that fully solves post-painting cracking and improves production yield
