SIENOX High‑Efficiency Defoaming Solution for 90,000‑cps Viscosity Gels


Working Condition Requirements: Perform high‑efficiency defoaming for 90,000‑cps gels (processing capacity of 1500 bottles per hour), especially removing fine and stubborn bubbles. With viscosity up to 90,000 cP, high‑viscosity gels feature extremely poor fluidity. Bubbles are firmly trapped inside gel network structures and hardly escape naturally. After defoaming, gels shall be uniform, fine and bubble‑free with stable cured properties to meet high‑quality requirements for sealing, potting and filling processes.


Comparison Before and After Improvement

Before Improvement: Severe bubble issues impaired product quality and production capacity for a well‑known manufacturer producing 90,000‑cps gel products. Conventional processing encountered multiple challenges:

• Extremely difficult bubble removal: 90,000‑cps gels have very poor fluidity. Fine and stubborn bubbles are locked within polymer networks. Traditional stirring and static settling can hardly eliminate bubbles, and massive residual bubbles still remain even after several days of standing.

• Insufficient production capacity: Traditional defoaming is time‑consuming. Each unit can only process a small quantity of products per hour, far below the target capacity of 1500 bottles per hour.

• Voids after curing: Trapped bubbles form internal voids and surface pits after gel curing, severely degrading sealing performance and surface appearance.

• Reduced thermal conductivity: Bubbles inside thermal‑conductive gels create thermal resistance, greatly lowering thermal conductivity and weakening heat dissipation performance.

• Degraded sealing reliability: Bubbles form micro‑channels in cured gels. Moisture and dust may penetrate along these paths, raising risks of sealing failure.

 

Solution: After extensive research, the enterprise learned about SIENOX defoamers and contacted us for technical support. Through detailed communication with the customer, SIENOX sales team clarified actual requirements and delivered professional defoaming solutions tailored for 90,000‑cps gels, and invited the customer for free sample testing.

The customer‑supplied samples featured ultra‑high viscosity and severe bubble entrapment. SIENOX adopted the advanced VH960 centrifugal defoamer for testing. Rigorous tests verified effective bubble removal with outstanding processing speed and performance. Nano‑scale bubbles can be eliminated within one minute, and single‑machine throughput reaches 1500 bottles per hour as required by the customer. SIENOX finalized optimal equipment parameters and processing schemes. Highly satisfied with the test results, the customer promptly placed an order.

Key Solution Highlights:

1. High‑speed centrifugal defoaming: VH960 centrifugal defoamer expels stubborn micro‑bubbles rapidly from gels via high‑speed centrifugal force to realize nano‑level defoaming.

2. Nano‑scale bubble removal: Nano‑sized bubbles are eliminated within one minute, far outperforming traditional static settling.

3. High‑capacity guarantee: Single unit processes 1500 bottles per hour to satisfy mass‑production demands.

4. Highly‑adaptable fixture design: Customizable fixtures fit various container specifications for diverse production scenarios.

5. Precise rotation‑speed control: Flexible speed adjustment adapts to different viscosity grades and defoaming requirements.

6. Automated operation: Manual intervention is not required, simplifying workflows and boosting productivity.
