High haze of transparent blends
Fenómeno do problema
The light transmittance and haze of the product do not meet transparent part standards
Análise das causas
The refractive indices of the two components of the blend do not match, causing light scattering; the dispersed phase size is 0.4-0.7μm (visible light wavelength range)
Solução
Match the refractive indices of the two components so that the difference is <0.01; control the dispersed phase size to be much smaller than the light wavelength (<0.1μm) or much larger (>5μm); reduce defects at the phase interface
Conclusão principal
The core of transparent blending lies in refractive index matching and phase size control
