In industrial fluid-handling environments, efficiency, uniformity, and process stability are fundamental to guaranteeing product quality and operational continuity. As manufacturers across the chemical, adhesive, coatings, pharmaceutical, food, and electronics sectors adopt increasingly complex formulations, the demand for precise inline mixing technologies has surged. Among these, the RMorRS Static Mixer stands out as one of the most reliable and effective solutions for accurate continuous mixing without mechanical movement.

With years of engineering expertise and a commitment to innovation, Contriu has become a trusted provider of high-performance RM and RS static mixers that help global manufacturers achieve superior mixing quality, reduced operational costs, and consistent batch-to-batch performance.

1. Understanding the RMorRS Static Mixer: A High-Efficiency Inline Mixing Solution

Static mixers—unlike dynamic mixers—contain no moving parts and rely entirely on engineered internal elements to divide, rotate, and recombine fluid streams. The RM and RS series static mixers are specifically designed to handle applications requiring:

Highly uniform mixing

Precise ratio control

Low shear environments

Continuous inline blending

Minimal maintenance

RM Static Mixer Characteristics

The RM series typically features a spiral or helical structure designed to create controlled turbulence and fluid splitting. This makes it ideal for applications such as two-component adhesives, resins, PU systems, and sealants.

RS Static Mixer Characteristics

The RS series includes a more advanced mixing geometry that enhances axial rotation and cross-flow blending, enabling superior homogenization even under low flow pressure.

Both designs offer excellent mixing accuracy, chemical resistance, and long operational life—qualities especially essential in automated production systems.

2. How RM and RS Mixers Work: The Engineering Behind Precision Mixing

The RMorRS Static Mixer operates based on fluid-dynamic engineering:

① Flow Division and Recombination

Each internal element splits the flow into multiple streams, which recombine further downstream. After each stage, the number of layers increases exponentially, ensuring rapid homogenization.

② Controlled Turbulence

Even at low Reynolds numbers, the mixer geometry induces micro-turbulence that enhances molecular blending without damaging sensitive materials.

③ Stream Rotation

The alternating twist direction of elements forces rotational flow, significantly improving blending efficiency for high-viscosity adhesives, silicones, foams, epoxies, and resins.

④ Pressure Drop Optimization

Contriu configures RM and RS mixers to balance mixing performance with minimal pressure loss, improving pump energy efficiency and extending equipment lifespan.

3. Key Application Fields Using RMorRS Static Mixers

• Adhesives and Sealants Manufacturing

Two-component adhesives (2K epoxy, polyurethane, acrylic systems) require precise flow ratio and perfect blending to ensure full polymerization. RM and RS mixers are widely used in industrial dispensing systems.

• Chemicals & Petrochemicals

Acid-alkali neutralization, catalyst dispersion, polymer blending, and additive introduction benefit from non-mechanical, contamination-free mixing.

• Electronics & Semiconductor Materials

Encapsulation materials, thermal interface compounds, and conductive adhesives require micro-level homogeneity.

• Pharmaceutical and Biotechnology

Shear-sensitive liquids, sterile drug components, and powder-liquid blending demand predictable inline mixing with no contamination risk.

• Food and Beverage Processing

Flavoring, coloring, emulsification, and nutrient incorporation rely on consistent inline blending.

Across these sectors, Contriu’s RMorRS Static Mixer consistently delivers reliable, repeatable performance under varied flow rates and viscosities.
