MS Foaming Agent Application
Problem Phenomenon
MS expandable copolymer with foaming agent added, autoclave process.
Cause Analysis
MS expandable copolymer beads and foaming agent, emulsifier and other additives are put into the autoclave; heat and pressurize for 6-10 hours; cool for 10-15 hours; sealed low-temperature storage; foaming quality.
Solution
①Foaming agent ratio; ②autoclave process; ③temperature and time; ④storage management; ⑤foaming quality.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Parameters and storage of MS foaming process are the key to quality; control ensures foaming effect; management prevents deterioration.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
