TPE Drying Graded by Hardness
Problem Phenomenon
High-hardness TPE agglomerates after drying, or low-hardness TPE is insufficiently dried and still has bubbles
Cause Analysis
TPE drying temperature is graded by hardness: Shore A0-60 uses 40-60℃, Shore A60-100 uses 60-80℃; soft material agglomerates at high temperature, hard material does not dry at low temperature; vacuum drying at 75-90℃×2h is universal
Solution
①Set the drying temperature graded by hardness; ②Soft TPE prefers low temperature for a long time; ③Vacuum drying oven at 75-90℃×2-3 hours; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
TPE drying temperature must match hardness; soft material uses low temperature to prevent agglomeration, hard material uses high temperature to ensure drying, with graded management; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
