Why is PU automotive sealant double planetary mixer needed?

1. Suitable for high-viscosity, high-filler systems
Double planetary stirring generates complex material flow trajectories.
The powered wall-scraping device reduces dead zones and material buildup on the walls.
Ensures thorough dispersion of fillers and base materials.
2. High mixing uniformity and batch stability
Combined planetary and rotational motion.
Effectively avoids localized over-mixing or insufficient mixing.
Improves batch consistency of automotive sealants.
3. Supports vacuum mixing, improving product quality
Effectively removes air bubbles generated during the mixing process.
Improves the density and appearance of the sealant.
Suitable for automotive-grade quality requirements.
4. Precise temperature control, suitable for PU processes
Jacketed heating / cooling.
Controls the reaction speed and viscosity changes of the system.
Enhances process controllability.
