TPE Transparent Parts
Problem Phenomenon
TPE transparent parts are cloudy and yellow, transparency does not meet the standard, and there is color difference between batches
Cause Analysis
TPE transparent parts require SEBS base material; SBS base material is not yellowing resistant; moisture and degradation affect transparency; color masterbatch carrier selection affects hue; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Choose SEBS-based TPE for transparent parts; ②Strictly dry to below 0.1%; ③Select the color masterbatch carrier by base material; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
The foundation of TPE transparent parts lies in SEBS; yellowing resistance and drying control are the guarantee of transparency; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
