Non-bleed UV blocking masterbatches

masterbatches with excellent light blocking properties, bleed resistance, and heat resistance. It achieves high hygiene, transparency, and non-coloring properties in fields such as medical, optical, food, and building materials that require protection of contents and base materials from external light, especially ultraviolet rays.

Product features

Feature 1: Achieves high transparency, non-coloring property, and heat resistance

Transmittance spectra of conventional product and developed product
The conventional product has absorption in the visible range (from 400 nm) and is colored yellow, whereas the developed product has light-shielding properties (from wavelength to 365 nm), achieving high transparency and non-coloring properties, improving visibility. Does not interfere.
It also has excellent heat resistance. (Thermal decomposition start temperature: 290℃)
