Poly Ethylene Glycol (PEG) Derivatives <SUNBRIGHT Series>

NOF has developed the following excellent quality of polymers (SUNBRIGHT Series)
which are well suitable for preparing pharmaceuticals and bio-medical products.
SUNBRIGHT Series consists of the extraordinary purified various functional polyethylene
glycols. SUNBRIGHT Series are the most appropriate DDS materials for PEG modified
drugs.
