TPE Toy Application
Problem Phenomenon
TPE toys are soft and safe, but ultra-soft material becomes sticky, or color masterbatch migrates
Cause Analysis
TPE toys are soft, safe, and easy to process; but ultra-soft TPE has much filling oil and is prone to stickiness; color masterbatch migration may contaminate; a toy-grade formulation must be selected; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Choose toy-grade TPE formulations for toys; ②Control the filling oil of ultra-soft material; ③Choose non-migrating color masterbatch; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
The safety boundary of TPE toys lies in the formulation; toy-grade grades plus non-migrating color masterbatch are the compliance basis; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
