Medmix Mixpac MBHX Helix Static Mixer Nozzles for B-System Cartridges

The Mixpac MBHX static mixer by medmix (formerly Sulzer Mixpac) is a disposable helix mixing nozzle for dispensing two-part adhesives from B-System AB cartridges. MBHX mixers are the 4:1 and 10:1 ratio version of the B-System helix line and carry a dust grey body with orange elements. The 1:1 and 2:1 version is the MBH, which has white elements. Nine models are available, differing in bore, element count, and tip style.

B-System or F-System: check your cartridge first

B-System and F-System nozzles are not interchangeable. B-System covers the smaller 45 ml, 50 ml, and 75 ml AB cartridges used for repair work, small assemblies, and sample quantities. F-System covers the larger 200 and 400 series cartridges used in production. If your cartridge holds 200 ml or more, you need an MFHX or MFQX instead.

Reading the MBHX model code

Using MBHX 05-16T as the example:

Choosing between the nine

All nine models fit the same B-System 4:1 and 10:1 cartridges. Four things change from model to model.

• Bore. The first two digits of the model code. A smaller bore holds less material, from 0.60 ml in the 3.2 mm 03-16S to 3.79 ml in the 6.5 mm 06-20T. A larger bore passes more material and generally gives more mixing margin, at the cost of more adhesive left in the nozzle.
• Elements. The 5.4 mm bore comes in 12, 16, and 20 elements (05-12D, 05-16T, 05-20T). More elements means more mixing passes and a longer nozzle. At 4:1 and especially 10:1 there is far less of the B side to distribute, so these chemistries can be less forgiving of a short mixer. Watch the bead before settling on a lower element count.
• Tip. Straight, tapered, or stepped. Compare 04-16D with 04-16S, or 06-16D with 06-16T. The tapered or stepped version is about 10 mm longer at the same bore and element count.
• Retained volume. On a 45 ml to 75 ml cartridge, 0.60 ml to 3.79 ml stays in the nozzle at every changeover. Worth factoring in if you swap nozzles often or dispense in small shots.

Compatible B-System cartridges

Running a 1:1 or 2:1 B-System cartridge instead? Use the MBH series with white elements or the MBQ series with green elements. The ratios do not interchange.

Dispensing guns for B-System cartridges

MBHX nozzles mount on the cartridge, so the gun has to match the cartridge size, ratio, and flange. Catalogue pairings for 4:1 and 10:1 B-System cartridges:

MBHX compared to the other B-System mixers

The B-System line uses element color to tell the ratio version apart. Orange elements mean 4:1 and 10:1. White or green elements mean 1:1 and 2:1.

Performance in production

• Helical elements blend the A and B sides as the material travels the length of the nozzle.
• B-System twist and lock connection mounts directly to the AB cartridge with no converter and no tools.
• Orange elements in a dust grey body make the 4:1 and 10:1 version easy to tell apart from the white element MBH at the bench.
• Four bores from 3.2 mm to 6.5 mm let you size the bead and the mixer to the joint without changing cartridge system.
• Straight, tapered, and stepped tips are available. The tapered or stepped version runs about 10 mm longer than straight at the same bore and element count.
• Disposable construction avoids purging and cleanup between adhesive batches, and the smaller models hold as little as 0.60 ml at changeover.

Common applications

• Small-batch and repair bonding from 45 ml, 50 ml, and 75 ml cartridges
• Off-ratio two-part chemistries that ship in 4:1 and 10:1 cartridges
• Electronics and small component assembly where a fine bead is needed from the 3.2 mm and 4.2 mm models
• Sample and trial dispensing before committing to a production cartridge size
• Field service and maintenance work with portable cartridge guns
• Dispensing epoxy, polyurethane, silicone, acrylic, and MMA two-part adhesives and sealants

Specifications

Ordering

The 05-16T and 06-20T are stocked and sold individually, so you can order one to test a material. The other seven models are sold by the case. Pair them with matching B-System cartridges and the guns above from the dispensers, mixers, and nozzles category. Call or email about case orders or availability on any model.

Frequently asked questions

What cartridges does an MBHX static mixer fit?

Mixpac B-System AB cartridges in 4:1 and 10:1 ratios, covering the 50 ml 4:1, the 45 ml and 50 ml 10:1, and the 75 ml 10:1 sizes. B-System nozzles do not fit F-System 200 or 400 series cartridges, which use the MFHX or MFQX instead.

What is the difference between MBHX and MBH mixers?

Element color and ratio. MBHX has orange elements and is built for 4:1 and 10:1 cartridges. MBH has white elements and is built for 1:1 and 2:1. Both use a dust grey body and mount to B-System cartridges, but the ratios do not interchange. Check the element color against the ratio printed on your cartridge.

Which MBHX model should I start with?

Set the bore by the bead and joint you need, then pick the element count. The 05-16T sits in the middle of the range on both bore and elements, which makes it a reasonable first test. If the mixed bead shows streaking, color variation, or uneven cure, step up to the 05-20T at the same bore, or to the 06-20T for the largest bore and the most elements.

What does MBHX 05-16T mean?

MBH is mixer, B-System, helix design. The X marks the 4:1 and 10:1 version with orange elements. The 05 is the inner diameter rounded down, actually 5.4 mm. The 16 is the number of mixing elements. The T is the stepped outlet tip. D means straight and S means tapered.

What is the difference between MBHX and MBQX mixers?

Element design. MBHX uses helical elements in a round bore and comes in nine models across four bore sizes. MBQX uses QUADRO elements in a square flow path, in a 5.3 mm bore with 16 or 24 elements. Both are built for 4:1 and 10:1 cartridges, both have orange elements in a dust grey body, and both mount to B-System cartridges.

Can I buy a single MBHX nozzle?

Yes, on two models. The 05-16T and 06-20T are stocked and sold individually, so you can order one to check fit or test a material. The other seven models are sold by the case.

How much adhesive stays in an MBHX nozzle?

From 0.60 ml in the 03-16S to 3.79 ml in the 06-20T. On a 45 ml to 75 ml cartridge that is a meaningful share of the pack, so it is worth factoring in if you change nozzles between shots rather than running a cartridge through on one nozzle. The size chart above lists every model.

Does an MBHX mixer need a converter or retaining nut?

No. The MBHX mounts directly to the B-System cartridge with a twist and lock connection. No converter, no retaining nut, no tools.
