silicone masterbatch color differences Causes:
– Inconsistent batch quality, poor dispersion, or large particle size of color masterbatch
– Insufficient mixing time / speed, inaccurate manual weighing
– Unstable curing temperature or time; discoloration during post-curing
– Variation in raw silicone material, product thickness, or mold surface
silicone masterbatch color differences Solutions:
– Use color masterbatch with particle size ≤20μm and ΔE<1.0
– Solid silicone: pre-disperse and remix for 15–20 minutes
– LSR: use static mixer and automatic dosing system (±0.5%)
– Control mold temperature at 160–180℃ (±2℃); post-cure ≤2h at 200℃
– Fix silicone material, mold, and process; use spectrometer for color control
