MS Impact Resistance Improvement
Problem Phenomenon
MS copolymerized with styrene improves PMMA brittleness, impact resistance improvement.
Cause Analysis
MS copolymerized with styrene improves the defect of PMMA being brittle and not impact-resistant; good transparency and gloss; relatively high impact strength; not high melt viscosity; relatively good flowability.
Solution
①Utilize copolymerization advantages; ②impact resistance verification; ③transparency management; ④flowability utilization; ⑤performance balance.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
MS copolymerization modification is the PMMA upgrade path; performance balance is the value; verification ensures application.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
