Industrial-Grade High Transmittance Light Diffusion Agent KS-200 Provide Even Diffusion – For LED Lighting & LCD Displays
KS-200 is a silicone polymer resin powder composed of three-dimensional polymer microspheres linked by siloxane bonds. When incorporated into resins of various materials, it disperses uniformly throughout the matrix in the form of fine, transparent glass-like microspheres, via compounding with different base materials.
Leveraging the difference in emissivity between components, KS-200 modulates the refraction behavior of incident light, altering its transmission path to achieve high uniformity and transparency of the material system. Simultaneously, it satisfies the requirements for both haze and light transmittance, yielding soft, pleasant luminous effects. KS-200 is primarily applicable to transparent resins such as PC, PVC, PMMA and PET, as well as LED components and color masterbatches.
- Withstands temperatures above 300°C, featuring excellent aging resistance, no yellowing or black spot formation.
- Boasts high light transmittance for energy efficiency, with low dosage requirements to reduce application costs.
- Narrow particle size distribution ensures stable optical performance.
- High haze value diffuses harsh incident light into gentle, eye-friendly soft light.
- Minimal light loss and high light diffusion efficiency fully satisfy the demanding requirements for enhanced brightness and energy conservation in LED lighting, packaging, light diffusion films and other related applications.
- When incorporated at a dosage of just 0.5–1% into transparent substrates including PC, PET, PMMA, PS and PVC, it delivers a light transmittance of over 86% paired with a haze value of more than 90%.
