Polyurethane Defoaming Machine


Resolve Bubbles and Foaming in Polyurethane Casting and Potting · Dense Castings Free of Voids with Stable Performance

Simultaneous Mixing and Air Extraction Under Vacuum + Suppression of Abnormal Foaming + Efficient Completion Within Short Operating Window

SIENOX polyurethane defoaming solution addresses the tendency of air entrapment and slight foaming after mixing of PU potting adhesive, elastomer and casting compound. It carries out mixing and air extraction under negative pressure to control foaming and eliminate bubbles, producing PU castings with dense interior, smooth surface and stable mechanical properties.

Why Polyurethane Defoaming Machine Is Required

PU Potting & Encapsulation Industry

PU potting adhesives are widely used for cushioning and waterproofing of automotive wiring harnesses, sensors and power modules. Air trapped after mixing creates voids inside the potting layer, which degrade sealing and cushioning performance and may cause cracking and liquid ingress under vibration and temperature cycling.

Polyurethane Elastomer Industry

Internal voids in PU elastomers, rubber rollers and buffer castings significantly reduce strength, wear resistance and rebound consistency. The compactness of castings directly determines the mechanical properties of finished products.

PU Coating & Bonding Industry

PU coatings and structural adhesives feature high reactivity after mixing. Air entrapment together with slight foaming during stirring leads to pinholes and bubbles after curing, impairing coating protection and bonding strength.

✨ Traditional Dilemma: Air entrapment from manual stirring plus inherent reactive foaming of PU; curing starts if defoaming is delayed. Conventional vacuum chambers have slow pumping speed and cannot keep up with the operating window. Therefore, a vacuum mixing solution that enables simultaneous mixing and defoaming is required.

Why Choose SIENOX PU Defoaming Solution

Simultaneous Mixing and Defoaming

Synchronous mixing and defoaming under vacuum shortens the process, completing the operation within PU pot life to prevent material thickening and curing.

Foaming Control via Negative Pressure

Controllable vacuum suppresses abnormal foaming. Castings become denser after defoaming with consistent mechanical properties.

Stable & Low-noise Without Ratio Deviation

Low-vibration equipment with non-contact mixing, maintains the proportion of multi-component PU materials, no cross-contamination and stable mass production.

✨ The MIX60 integrates three core capabilities: deep vacuum defoaming, precision small sample processing, and reproducible process parameters. It is an ideal device for laboratory R&D requiring vacuum-assisted defoaming.

Precautions for Use

PrecautionsOperating Instructions
Ratio & Material TemperatureStrictly control the ratio of multi-components and material temperature; preheat to reduce viscosity before defoaming when necessary.
Pot LifePU has high reactivity. Complete casting promptly after defoaming with compact operation to avoid thickening caused by expired pot life.
Vacuum LevelAdjust vacuum level and duration according to formulation to prevent abnormal foaming caused by excessive pumping.
Slow Pressure ReliefRelease pressure slowly before opening the lid after defoaming to prevent re-bubbling on the surface of casting compound.
