Obvious transparency decrease of modified transparent ABS (methyl methacrylate-acrylonitrile-butadiene-styrene copolymer)
Problem Phenomenon
Transparency of modified transparent ABS (methyl methacrylate-acrylonitrile-butadiene-styrene copolymer) decreases obviously, haze increases, not meeting transparent product requirements
Cause Analysis
Additives do not match the refractive index of transparent ABS (methyl methacrylate-acrylonitrile-butadiene-styrene copolymer)
Uneven additive dispersion produces scattering
Processing temperature too high, additives degrade and discolor
Excessive addition amount affects transparency
Crystallinity changes affect transparency
Solution
Select additives with matching refractive index
Ensure uniform additive dispersion
Control processing temperature to avoid additive degradation
Reduce addition amount
Control crystallization conditions
Key Takeaway
Transparency decrease needs to start from refractive index matching and dispersion
