Product Feature:
In the polymerization process the comonomer is added, which is an improvement made on the basis of BG802. The comonomer can absorb the ultraviolet wavelength thus nutrients are effectively kept in the drinks and their shelf time are extended.
Compared with traditional anti-UV processing method, the bottles look colorless and transparent after injection molding. Moreover, the processing flow is simplified and the processing cost is also reduced.
Product Application:
Bottles with anti-UV properties for edible oil and medicines, transparent thin sheet materials.
