Discontinued - Xemex X2-B8-7 Ultra-Low Waste Mixing Nozzles (Bell style) for larger cartridges like 200ml, 400ml, 600ml, 1500ml (1:1, 2:1, 4:1, 10:1)

Product Name

Xemex X2-B8-7 Ultra-Low Waste Mixing Nozzles (Bell style) for larger cartridges like 200ml, 400ml, 600ml, 1500ml (1:1, 2:1, 4:1, 10:1)

Brief Description

These are static mixing nozzles designed for efficiently blending two-part adhesives, sealants, and other reactive materials from large volume cartridges (200ml to 1500ml) with various mix ratios (1:1, 2:1, 4:1, 10:1). They feature a bell-style connection and utilize patented Xemex technology to achieve superior mixing with significantly reduced material waste compared to traditional mixers.

Popular Applications & Uses

- Dispensing two-component epoxies, methacrylates, urethanes, and silicones.- High-volume adhesive applications.- Manual and automated dispensing systems.- Bonding, sealing, potting, and encapsulating in various manufacturing and assembly processes.- Applications requiring precise bead control, often with luer lock tips for needle attachments.

Industries that Commonly Use It

- Aerospace/Defense- Automotive Service/Repair- Cabinet & Woodworking- Construction/ Building Services- Countertop- Distributers & Resellers- Electrical Services or Products- Energy- Engineering Services- Fabrication- Furniture- General Manufacturing- LED/Electronics- Marine- Medical Device/ Prosthetics- Metal Fabrication- Mold Making/ Casting- Plastic Fabrication- Sign & Display- Transportation/ Specialty Vehicle

Special and Unique Features

- **Ultra-Low Waste Design:** Reduces material waste by up to 75% due to a shorter profile and efficient mixing elements.- **Patented Xemex Mixing Technology:** Utilizes a novel internal geometry (Xemex transformation) that achieves superior mixing with significantly fewer elements (e.g., 7 elements equivalent to 32+ traditional elements).- **Bell Connection:** Designed for compatibility with most standard large-volume cartridges (200ml, 400ml, 600ml, 1500ml) and meter-mix dispensing systems.- **Versatile Mix Ratios:** Compatible with 1:1, 2:1, 4:1, and 10:1 adhesive ratios.- **Compact and Rigid Design:** Shorter length (e.g., 50mm or 78mm) improves operator dexterity, accuracy, and eliminates automation accuracy problems.- **Reduced Air Entrapment:** Engineered to minimize air bubbles during mixing.- **Stepped or Luer-Lock Tips:** Allows for adjusting bead size or attaching precision dispensing needles.- **Made in the USA:** Ensures faster, more reliable lead times and supply chain security.

Key Properties

- **Housing Material:** Typically high-grade polypropylene.- **Insert Material:** Often polyester (yellow) for moisture-sensitive formulations.- **Mixing Elements:** 7 or 8 patented elements, providing mixing equivalent to 24-32+ traditional elements.- **Retained Volume:** Ultra-low, e.g., 0.6 mL to 2.5 mL, significantly reducing adhesive waste.- **Inner Diameter:** Varies, e.g., 5.3 mm to 8.7 mm, to accommodate different flow rates.- **Compatibility:** Designed for two-component materials like epoxies, polyurethanes, methacrylates, and silicones.

Surface Compatibility

These nozzles are compatible with a wide range of two-part adhesive and sealant chemistries, including epoxies, methacrylates, urethanes, silicones, and acrylics. The mixed materials are then applied to various substrates, making the nozzle's compatibility primarily with the chemical formulation rather than the end surface.

Known backups / known substitutes

- **Xemex X2-C8-8S:** This is the direct replacement/newer design for the X2-B8-7, offering 8 elements and similar ultra-low waste features.- **Other Bell-Style Static Mixers:** General bell-style static mixers from brands like Infinity Bond, MixPac (e.g., MCH series, MFHX series), and Nordson EFD are common alternatives, though they may not offer the same ultra-low waste or compact design benefits.- **Maven F-System series static mixing nozzles:** Mentioned as backup parts for MedMix products.

Comparison Note

Xemex X2-B8-7 (and its replacement X2-C8-8S) significantly outperforms traditional helical or square static mixers by achieving superior mixing with fewer elements (e.g., 7-8 elements vs. 24-32+) and a much shorter length. This results in up to 75% less material waste, lower retained volume, and reduced back pressure, making them more cost-effective and precise, especially for high-value adhesives and automated dispensing. Traditional mixers often require more elements and length to achieve comparable mixing quality, leading to higher material waste.
