FEATURES
Core Product Technical Specifications — PP Foam Flotation Ball and MuCell Microcellular Foam
1.1 Product Overview — Dehumidifier Proximity Switch PP Foam Component
The Dehumidifier Proximity Switch PP Foam Component is a precision-engineered flotation ball that serves as the critical sensing element in water level control systems for dehumidifiers. When water levels rise in the dehumidifier reservoir, the PP foam flotation ball floats upward, activating a magnetic reed switch or proximity sensor that triggers an automatic shut-off or alarm mechanism.
PP foam flotation balls are widely used in dehumidifiers, humidifiers, water dispensers, coffee machines, air conditioners, medical devices, and industrial liquid level control systems. Their primary function is to provide reliable, non-electrical liquid level detection with exceptional durability and chemical resistance.

Mold temperature 30–60°C Higher temp improves surface finish but extends cycle time
Injection speed Medium–fast Faster speed improves fill but may cause jetting
Packing pressure Reduced vs. solid molding Foaming reduces packing requirement; excess packing collapses cells
Back pressure Low (for physical foaming) Maintains supercritical fluid in solution until injection
Cooling time Determined by wall thickness Sufficient cooling required before ejection to prevent distortion
Shot volume Compensation for foam expansion Larger shot volume needed than solid equivalent
MuCell® specific parameters:
Supercritical fluid: N₂ preferred for PP (higher solubility) or CO₂
