BIOSORB® 3638 is based on benzoxaxinone structure which delivers a short-term heat stability up to 350 °C and a long term heat stability up to 160 °C. By a proprietary process, BIOSORB® 3638 is made to dissolve quickly in PET resin and to give a transparent appearance even with high dosage. Due to these non-staining and transparent properties, BIOSORB® 3638 is ideal for film/sheet/plate applications such as solar cell, window film, etc.
