Polymer materials contribute greatly to a wide range of fields such as fibers, rubbers, resins, paints, and adhesives.
We deal in azo polymerization initiators and reactive UV absorbers, which are necessary for polymer production, as related materials.
Azoic polymerization initiators
Polymer chemistry technology contributes greatly to the fields of fibers, rubber, resins, paints, or adhesives.
Otsuka Chemical sells azo polymerization initiators and has a lineup of products to meet various needs.
UV absorber RUVAｰ93
What are UV absorbers?
The ultraviolet rays found in sunlight and lighting cause photochemical reactions when they make contact with plastic. This has a dramatic effect on such essential physical properties of plastic as color and strength, causing degradation.
Ultraviolet absorbers are one of the additives used to prevent plastic characteristics from deteriorating in environments where ultraviolet light is present.
UV absorber mechanisms
Ultraviolet absorbers protect materials by converting absorbed ultraviolet rays into low-impact heat and energy through chemical reactions. Ultraviolet absorbers are mainly used to curtail photodegradation in plastics by playing a key role in suppressing the generation of radicals that cause plastic to degrade.
UV absorber RUVAｰ93
The reactive UV absorber RUVA-93 easily polymerizes with styrene, methacrylate, acrylonitrile, and other compounds to incorporate UV absorbing functional groups into the polymer chain.
