UV Absorber Selection Guide for Engineering Polymers

The attached UV Absorbed selection guide outlines polymer systems and applications.   

 

SperseStab 3290 (tinuvin 329) is ideally suited for polycarbonate and PC/ABS systems as well as PET and PMMA polymers.  It is ideal for injection moulding and sheet applications.

 

SperseStab 3234 (tinuvin 324) is ideally suited for PC, PET as well as poly-amide (nylon) and POM (polyacetal).   used for film and sheet applications and offers low volatility and extraction resistance.   

​

SperseStab 3360 (tinuvin 360) is excellent for coextrusion sheet, films and fiber applications as well as complex moldings of PC, PC/ABS, PET, PA, PMMA and POM.   The extremely low volatility allows for high concentrations in coextrusion layers without the need for a neutral top layer.

​

SperseStab 3030 (Uvunul 3030) is a cyanoacrylate UV absorber ideal for PC and PET applications.   It offers excellent initial and long term stability.  Is Highly extraction resistant and thermally stable in PC and PET.   SperseSTab 3030 does not interact with residual catalysts eliminating potental for chomophores.  

​

SperseStab 3577 (tinuvin 1577) is a hydroxyphenol triazine UV absorber with very high molar absrobtivity which allows for use at lower concentrations.   Works in both PC and PC/ABS applications as well as PET fib
