Light Yellow Crystalline Powder Benzophenone UV Absorber for
polyolefin / PVC / polystyrene
Quick Detail :
BP - 1 protects plastics from being trans - natured by light, and
is also the intermediate for other benzophenone UV absorbers .
- Name : BP - 1
- Chemical name : 2 , 4 - Dihydroxybenzophenone
- CAS No. : 131 - 56 - 6
The main application of BP1 is as light stabilizer in plastics ,
which can effectively protect PMMA and clothing materials for being
transnatured by light . It is also the intermediate for compounding
other UV absorbers .
BP - 1 BP1 is also applicable to polyolefin , PVC and polystyrene .
BP1 is used as UV absorber , by which the Benzophenone like UV - 9
, UV - 531 and the monophydroxy , dihydroxy , trihydroxy and
tetrahydroxy compounds can be derived , which are the most widely
used absorbing light stabilizers , which can absorb UV light from
290 to 400nm and be widely applied to polymer materials with its
good compatibility with synthetic resin . 2 , 4
Dihydroxybenzophenone is applicable to PVC , polystyrene , epoxy
resin , cellulosic resin , coating and synthetic rubber , with its
greatest absorption wavelength from 280 to 340nm and its general
amount from 0.1% to 1% . But this product is not prominent in
keeping light stability . The LD50 is 8600mg/kg for white rat
orally and 2336 mg / kg for white mouse orally .
