Difficulty of MABS products achieving high transparency and impact toughness simultaneously
Problem Phenomenon
It is difficult for MABS products to achieve high levels of transparency and impact toughness simultaneously; transparency decreases when toughness is improved
Cause Analysis
MABS rubber component increases toughness but scatters light and reduces transparency
Contradiction between rubber particle size and transparency: large particles have good toughness but strong scattering
Improper processing temperature, rubber particle deformation affects transparency
When adjusting the ratio, transparency and toughness change in opposite directions
Refractive index matching difficulty increases with rubber content
Solution
Select MABS models with refractive index-matched rubber particles
Optimize rubber particle size (0.1-0.3μm) to balance toughness and transparency
Control processing temperature at 210-250°C
Weigh transparency and toughness targets to select appropriate grades
Use core-shell structure rubber particles to reduce scattering
Key Takeaway
MABS transparency-toughness balance needs particle size and refractive index optimization
