CHIMEI CORPORATION's Polycarbonate WONDERLITE®

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®

Features

Environmentally friendly
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.
Easy to mold
Mold corrosion and mold deposit, which are problems of the conventional method (phosgene method), are drastically diminished.

Less mold corrosion by chlorine, which is a problem of the conventional method.
Less oligomers and less mold deposit, which occurs during manufacturing, result in a decrease in maintenance frequency with a productivity enhancement.
Excellent liquidity enables molding of thin-wall structures or complex shapes and can lower the molding temperature.
