New Product – OMNISTAB® BR40: Empowering High-End Optical Products

In optical films, displays, LED lighting, and protective eyewear, UV and blue light are major causes of yellowing and aging over time. To address these challenges, we are introducing OMNISTAB BR40 – a specialized additive for optical materials that combines high transparency with excellent blue‑light protection.

Omnistab BR40 transmission spectrum

Key Advantages

• Broad‑spectrum light protection – Maximum absorption at 363 nm. When combined with a UVB absorber, it provides full coverage from 280–410 nm, blocking both UV and high‑energy short‑wave blue light to reduce material degradation.

• Low color & high clarity – Pale yellow solid with low color contribution; does not cause yellowing or increased haze. Preserves the original clarity and transparency of displays, optical films, and clear plastic parts – ideal for high‑spec optical applications.

• Good process compatibility – Soluble in various solvents and compatible with PC, PMMA, PET, TPU, and more. Resists migration, blooming, and exudation during processing.

Main Applications

• Electronic and automotive displays (phone/tablet screen covers, vehicle display covers)

• Backlighting and lighting (LED lamps, diffusion films for backlight modules)

• Optical lenses, safety goggles, AR/VR devices

• Optical‑grade plastics (PC, PMMA, PET, TPU, etc.)
