Asahi Kasei Chemicals is the first company in the world to develop a polycarbonate manufacturing process using carbon dioxide as a raw material.
Using the above-mentioned technology, Chimei Corporation (Taiwan) manufactures WONDERLITE®
The manufacturing process of WONDERLITE® does not require phosgene and methylene chloride, both of which are used in the conventional method (phosgene method) and are highly toxic.
Mold corrosion and mold deposit, which are problems of the conventional method (phosgene method), are drastically diminished.
