应城UV absorber OPS

Common name: UV absorber OPS

Chemical name: n-octylphenyl salicylate

English name: 4-n-octylphenylsalicylate

Molecular formula: C21H26O3

Relative molecular weight: 326.43

Appearance: White crystal

Melting point: 72~74 ℃

Boiling point: 435.1 ℃ (760mmHg)

Relative density: 1.076

Solubility: The solubility (g/100g solvent) in the following solvents at 27 ℃ is 127.2 for acetone, 144.0 for benzene, 37.0 for ethane, 4.5 for ethanol, and<0.1 for water, respectively

Absorption range: 290~330nm

Application performance: This product is a UV absorber for polyolefins, with poor ability to absorb UV rays. After exposure to light, it undergoes ortho rearrangement, significantly absorbing visible light, resulting in yellowing of the product. However, these compounds are inexpensive and have good compatibility with resins, making them still widely used.

Dosage: 0.1-1.0 parts

Safety: The product has low oral toxicity. Mice did not die after oral administration of 3.2g/kg. Non flammable and non corrosive
