the maximum absorption spectrum wavelength: 374nm
the maximum fluorescence emission wavelength: 434nm
application:
fluorescent brightener ob-1 fluorescent whitening agent is effective for a polyester fiber, and is widely used in abs, ps, hips, pa (nylon), pc (polycarbonate), pp, eva and hard pvc and other plastics, has excellent whitening effect, excellent thermal stability, minimal amount of features.
Dosage: 100kg per polymer added fluorescent whitening agent ob-1 amount (reference amount)
transparency: dosage 0.0025-0.005% (2.5g-5g)
general dosage is: 0.0025-0.025% (2.5g-25g)
not more than 0.03% (30g)
when you add any ultraviolet absorber in the polymer, should pay attention to adjust the fluorescent brightener ob-1 optimum dosage.
Usage:
due to less amount whiteners, brighteners should be thoroughly dispersed, so brightener is uniformly dispersed throughout the polymer. If brightener masterbatch concentrate is easier to achieve sufficient dispersion effect.
Note:
for pe and pvc soft fluorescent brightener ob-1, should pay special attention to the amount of control, excessive amount of brightener migration phenomenon will occur.
Package:
25kg drum (lined with double plastic bag)
security and management:
it can be used as a general industrial chemicals management, wear gloves and protective glasses, avoid direct contact with skin or eyes should be used. If the stained skin with water and soap and rinse plus.
