4. Physical properties
1) molecular weight: 480.7
2) appearance: white crystalline powder
3) melting point: 81-85°C
4) content: 99%min( hplc)
5). Transmittance: 425nm ≥97%, 500nm ≥98%
 
5. Property:
1) odorless, don’t bring smell to polymers.
2) very stable to heat and can be used in plastic which require high processing temperature.
3) high compatibility with a wide range of polymers and provide superior light protection             for a broad range of polymers against the harmful effect of UV radiation.
4) produce no effect on initial color of substrates.
5) provide high synergistic effect with other UV absorber.
 
6. Application:
1) polystyrene: 0.3-0.5 wt% for ABS; 0.2-0.3 wt% for PS; 0.2-0.3 wt% for HIPS
