Disposable Static Mixers

Price range: $8.25 through $12.95

Disposable Static Mixers are single-use inline mixing devices designed for precise blending of two-component materials such as epoxies, polyurethanes, silicones, adhesives, and resins.

What Are Disposable Static Mixers?

They consist of a plastic housing (polypropylene or acetal) with internal helical or corrugated mixing elements.
As the two components flow through the mixer, the elements repeatedly divide, rotate, and recombine the streams to achieve thorough, homogeneous mixing without any moving parts.

After use, the mixer is simply discarded — eliminating cleaning, cross-contamination, and curing issues common with reusable mixers.

Key Benefits

Zero Cross-Contamination Fresh mixing every time — no residue from previous batches.
No Cleaning Required Eliminates hazardous solvents and labor-intensive cleaning.
Easy to Use Attaches directly to standard dual-cartridge guns and dispensing equipment.
Cost-Effective Low cost per mix and reduced downtime compared to cleaning reusable mixers.

Disposable Static Mixers are the ideal solution for manufacturing, electronics, medical devices, construction, and automotive applications where precise, reliable mixing of two-part materials is required without the hassle of cleaning.

Disposable Static Mixers are single-use, high-efficiency inline mixing devices that engineers specifically design for the precise blending of two-component reactive materials.
Furthermore, manufacturers widely use these mixers across many industries, including manufacturing, electronics, medical device assembly, construction, automotive, and aerospace. In addition, they deliver consistent, repeatable mixing results while completely eliminating cross-contamination. As a result, companies achieve higher product quality and significantly reduce downtime. Moreover, disposable static mixers eliminate the need for cleaning between batches, which saves time and lowers operating costs in critical production environments.

What Are Disposable Static Mixers?

Unlike reusable industrial static mixers, manufacturers design disposable static mixers specifically for one-time use.
Furthermore, these mixers consist of a plastic housing — typically polypropylene or acetal — that contains a series of fixed helical or corrugated mixing elements. As the two components (A + B) pass through the mixer via a dispensing gun or pump, the elements repeatedly divide, rotate, and recombine the flow streams. As a result, they achieve thorough and homogeneous mixing in a very short distance.
In addition, operators attach these mixers directly to dual-cartridge systems or meter-mix dispensing equipment. After dispensing the required volume, workers simply discard the mixer. Consequently, they eliminate the need for solvent flushing, curing inside the mixer, or time-consuming cleaning.

Key Design Features

  • Compact & Lightweight – Small diameter (¼” to 1″) for easy handling and attachment to handheld dispensing guns.
  • Intensive Mixing Elements – Typically 8 to 32 helical or tabbed elements optimized for high shear and radial mixing.
  • High Mixing Efficiency – Achieves Coefficient of Variation (CoV) below 5% for most two-part systems.
  • Material Compatibility – Polypropylene or acetal housings resist most epoxies, polyurethanes, silicones, acrylics, and adhesives.
  • Connection Options – Bell inlet for standard cartridges, threaded, Luer Lock, or barbed outlets.
  • Pressure Rating – Up to 300–400 psi (20–28 bar), suitable for most manual and pneumatic dispensing systems.

Typical Applications

Disposable static mixers are the preferred choice wherever two-component reactive materials must be mixed accurately and reliably without cleaning between uses:

  • Two-part epoxies, polyurethanes, and silicones for bonding and sealing
  • Acrylic adhesives and methacrylates
  • Dental materials and medical device adhesives
  • Potting compounds and encapsulants in electronics
  • Construction adhesives, anchor bolts, and crack repair
  • Automotive and aerospace structural bonding
  • Any application requiring precise mix ratios and elimination of cross-contamination

Advantages Over Reusable Mixers

The primary benefit of disposable static mixers is the complete elimination of cleaning and curing issues. Traditional reusable mixers often become clogged with cured material, require hazardous solvents for cleaning, and can introduce contamination between batches.
Disposable mixers solve these problems by being discarded after each use, ensuring fresh, uncontaminated mixing every time while saving significant labor and downtime.

From high-precision medical device assembly to heavy-duty construction bonding, disposable static mixers have become an indispensable tool wherever two-component materials must be mixed reliably, consistently, and without the hassle of cleaning.

Disposable static mixers (typically polypropylene or acetal) are designed for low-to-moderate flow rates and produce relatively high pressure drop due to their small diameter and intensive mixing elements.
Recommended design range: 10 – 40 psi for effective mixing in single-use applications.

Key Notes on Pressure Drop for Disposable Static Mixers

  • Disposable static mixers are intentionally small in diameter to achieve intense mixing in a short length, which results in higher pressure drop compared to industrial inline static mixers.
  • They are commonly used for two-component adhesives, resins, sealants, and other reactive materials in single-use applications.
  • Pressure drop increases rapidly with flow rate due to the narrow flow path and multiple mixing elements.
  • Typical design target is 10 – 40 psi to ensure thorough mixing while remaining within the capabilities of standard dispensing equipment.
  • Higher viscosity materials (epoxies, polyurethanes, silicones) will produce significantly higher pressure drop than water values shown above.
  • Disposable mixers are not intended for continuous high-flow industrial service — they are optimized for intermittent, single-use dispensing.

Disposable Static Mixers are widely used in manufacturing, construction, electronics, and medical device assembly where precise mixing of two-part materials is required without cleaning or cross-contamination.
The pressure drop curve is critical for selecting the correct mixer size and ensuring the dispensing pump or cartridge system can deliver the required flow rate.

For accurate pressure drop data based on your exact flow rate, material viscosity, and specific disposable mixer model (element count, diameter, material), consult the manufacturer’s technical data sheet or request a custom curve.

Installation

Disposable Static Mixers are designed for quick and simple attachment to dual-component cartridge systems or meter-mix dispensing equipment.
Proper installation ensures complete mixing, prevents leakage, and avoids cross-contamination.

Installation Procedures for Disposable Static Mixers

Step Installation Procedure Tools / Materials Required Safety & Important Notes
1 Select the correct disposable static mixer size and element count based on the material viscosity, mix ratio, and required mixing quality. Mixer selection chart or manufacturer recommendation Using the wrong mixer can result in poor mixing or excessive pressure.
2 Ensure the dual-component cartridge or dispensing system is properly loaded and the pistons are aligned. Purge a small amount of material to remove any air from the cartridge outlets. Dispensing gun or meter-mix machine Air bubbles can cause incomplete mixing and off-ratio material.
3 Attach the disposable static mixer firmly to the cartridge outlet. For bell-type inlets, push and twist until it locks securely. For threaded or Luer Lock connections, tighten until snug. None (hand installation) Ensure a tight seal to prevent leakage or material bypass.
4 If using a dispensing gun, prime the system by dispensing a small amount of material (usually 1–2 full mixer lengths) until the mix color is uniform and consistent. Waste container for purging Discard the initial purge to ensure fully mixed material is used.
5 Begin dispensing the mixed material onto the workpiece. Maintain steady pressure and speed for consistent bead size and mix quality. Dispensing gun or automated system Avoid stopping mid-dispense for long periods to prevent material curing inside the mixer.
6 When finished, immediately remove and discard the used mixer. Do not attempt to clean or reuse it. Waste container Cured material inside the mixer can block future use and cause off-ratio dispensing.

Important Notes for Disposable Static Mixers:

• Always match the mixer size and element count to the material viscosity and mix ratio.
• Purge the first 1–2 mixer lengths to ensure fully mixed material before applying to the workpiece.
• Never attempt to reuse a disposable mixer — cured material will cause poor mixing and equipment damage.
• Store unused mixers in a cool, dry place away from direct sunlight.
• For automated systems, ensure the dispensing pressure does not exceed the mixer’s rated limit.

Correct installation and usage ensure consistent mixing quality and prevent costly defects or equipment issues.

Maintenance

Disposable Static Mixers are single-use devices designed to be discarded after each application.
Because they contain no reusable components and are intended for one-time use only, traditional maintenance is not applicable.
Instead, proper handling, storage, and disposal procedures are essential to ensure mixing quality and prevent safety or contamination issues.

Important Notes for Disposable Static Mixers:

• These mixers are intended for single-use only. Attempting to reuse them can cause poor mixing, off-ratio material, or equipment damage.
• Always purge the first 1–2 mixer lengths to ensure fully mixed material is applied to the workpiece.
• Never try to clean or flush a disposable mixer with solvent — cured material inside the elements makes cleaning impossible and unsafe.
• Proper storage and handling prevent degradation of the plastic housing and mixing elements.
• Dispose of used mixers responsibly according to local chemical and plastic waste regulations.

Following these procedures ensures consistent mixing quality, prevents defects, and maintains safety in your dispensing process.

Q&A

Question Answer
What are Disposable Static Mixers? Disposable Static Mixers are single-use inline mixing devices designed to thoroughly blend two-component materials such as epoxies, polyurethanes, silicones, adhesives, and resins. They consist of a plastic housing with internal helical or corrugated mixing elements and are discarded after each use.
Why use disposable mixers instead of reusable ones? They eliminate the need for cleaning, prevent cross-contamination between batches, and avoid cured material buildup inside the mixer. This saves time, reduces labor, eliminates hazardous solvent use, and ensures consistent mix quality every time.
How do Disposable Static Mixers work? The two components enter the mixer and are repeatedly divided, rotated, and recombined by the internal helical or corrugated elements. This creates intensive radial mixing, resulting in a homogeneous blend by the time the material exits the mixer.
What materials can be mixed with disposable static mixers? They are ideal for two-part epoxies, polyurethanes, silicones, acrylic adhesives, methacrylates, dental materials, potting compounds, and many other reactive adhesives and sealants.
