advantage and

application

uv-312 is a uv absorber having maximal thermal stability and minimal volatility. it will not decolor when meet with the metal ions, and particularly effective to short wavelength uv light. so it is often been used as brightener and uv light curing stabilizer. uv-3030 is recommended for added in pa, pc, pvc, pu and pet/pbt resin.
