POE shrinkage unstable
Fenómeno del problema
POE product shrinkage fluctuates ±0.8%, exceeding ±0.2% requirement
Análisis de la causa
Molecular weight differences between POE batches cause shrinkage variation; processing temperature fluctuation affects crystallinity and thus shrinkage
Solución
1) Strictly control raw material batch consistency; 2) Processing temperature stable ±2°C to ensure consistent crystallinity; 3) Mold shrinkage compensation reserves adjustment space
Conclusión clave
Shrinkage instability is caused by batch differences and temperature fluctuation; raw material and temperature control are key
