PCL plasticizer application
Problem Phenomenon
PCL as a plasticizer for other plastics, compatibility and migration problems.
Cause Analysis
Compatibility of PCL with matrix plastics; plasticizing effect; migration; durability; cost-effectiveness.；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Compatibility assessment; ②Addition amount optimization; ③Migration testing; ④Durability verification; ⑤Cost analysis.；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Compatibility of PCL plasticizer application is the prerequisite; tests verify effect and durability; cost decision.；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
