Conductive Rubber Tubing & EMI Shielding Sleeves: Advanced Static Control Solutions
Don't Let Static Friction Spark a Disaster.
Standard silicone is an excellent electrical insulator. However, in dynamic applications—such as peristaltic pumping or powder transfer—friction generates static electricity (triboelectric charging). If trapped, this charge can arc, causing explosions in volatile environments, clogging inkjet nozzles, or frying sensitive circuit boards.
At RISEUP, we engineer Conductive Tubing that acts as a flexible grounding system. By impregnating the silicone matrix with conductive carbon or metallic fillers, we turn the tubing itself into a path of least resistance, safely bleeding off excess charge to the ground.
Why Upgrade from Standard Conductive Silicone Rubber Tubing?
• Safety First: Prevent spark risks in ATEX/Ex-zones and solvent handling.
• Process Purity: Eliminate “static cling” that causes dust accumulation or ink satellites in digital printing.
• Signal Integrity: Use as a flexible EMI/RFI Shielding Sleeve to protect cable harnesses from electromagnetic interference.
The Conductivity Spectrum: Precision Engineered Ohms
One Size Does Not Fit All. Select Your Resistivity.
“Silicone Electrical Conductivity” isn’t a binary switch; it’s a spectrum. We tailor the volume resistivity of our hose silicone rubber to match your specific application, balancing electrical performance with mechanical flexibility.
1. Static Dissipative / ESD Safe ( to )
• The Function: Allows static charges to bleed off slowly and safely.
• Why use it: Essential for powder transfer and sensitive electronics assembly where a “hard ground” could shock components.
• Material: Carbon-loaded Conductive Silicone.
2. Low-Ohm Conductive / Grounding ( to )
• The Function: Provides a consistent path to the ground.
• Why use it: For connecting conductive components and ATEX zone fluid transfer.
• Material: High-structure Carbon Black.
3. EMI/RFI Shielding Grade (< )
• The Function: Acts as a flexible Faraday cage.
• Why use it: To slip over cables and wiring harnesses, blocking external electromagnetic interference (EMI).
• Material: Nickel-Graphite or Silver-Plated Aluminum filled Electro Conductive Silicone Rubber.
Structure Innovation: Beyond Basic Black Electrically Conductive Silicone Tubing
Co-Extrusion Technology—Grounding Without Compromise.
Standard conductive tubing relies on Carbon Black, forcing the entire tube to be opaque black. This creates two problems: you can’t see your fluid, and the exterior of the tube is electrically live. We solve this with advanced Multi-Layer Co-Extrusion.
1. Conductive-Lined Co-Extrusion (Inner Black / Outer Color)
• The Design: Electrically Conductive rubber inner layer + Insulating outer layer.
• The Advantage:
• Safety: Exterior is silicone electrically conductive insulated.
• ID: Outer layer can be color-coded (Red/Blue).
2. Striped Grounding Tubing (Transparency + Grounding)
• The Design: Clear silicone tube with an embedded conductive black stripe.
• The Advantage:
• Flow Visibility: See fluid, bubbles, or blockages.
• Grounding: Stripe acts as a built-in grounding wire.
3. Solid Homogeneous Conductive (The Standard)
• The Advantage: Maximum shielding effectiveness for EMI sleeves.
Advanced Filler Technology: Beyond Basic Carbon Black
Solving the "Dirty Tube" Problem.
Not all conductive fillers are created equal. While competitors use cheap furnace black that sheds particles (sloughing), we offer application-specific filler technologies.
1. Low-Sloughing Carbon (For Printing & Medical)
• Our Solution: High-purity carbon blended into a Platinum-Cured matrix. Locks particles tight, reducing sloughing by 95%.
• Best For: Inkjet systems, peristaltic pumps.
2. Silver & Nickel Graphite (For EMI Shielding)
• Our Solution: Silver-Plated Aluminum or Nickel-Graphite fillers.
• Benefit: Metal-like conductivity (<10 Ω) with rubber flexibility.
3. FDA-Compliant Conductive Grades
• Our Solution: FDA 21 CFR 177.2600 compliant grades for food processing grounding.
Industry Applications: Where Static Control Matters
Critical Solutions for Printing, Electronics, and Safety.
1. Digital & Industrial Printing (Inkjet Systems)
• The Challenge: Static causes “ink satellites” (mist) and clogged nozzles.
• Our Solution: Low-Sloughing silicone electrical conductivity Tubing grounds the ink path for sharper images.
2. Electronics & Cable Jacketing (EMI Shielding)
• The Challenge: Noise disrupts sensitive data lines.
• Our Solution: Metal-Filled Sleeves create a flexible Faraday cage (-60dB attenuation).
3. Explosive Environments (ATEX / HAZLOC)
• The Challenge: Solvent transfer sparks in Zone 1.
• Our Solution: Groundable Assemblies prevent ignition energy accumulation.
4. Peristaltic Pumping (Life Sciences)
• The Challenge: Roller friction generates static charge.
• Our Solution: Co-Extruded Striped Tubing handles wear while grounding the charge.

Technical FAQ: Engineering the Right Connection
Q: Does conductive filler affect temperature range? A: Minimally. Retains -50°C to +200°C range.
• Q: Can I get “Transparent” conductive tubing? A: Fully conductive is opaque. Use our Co-Extruded Striped Tubing for visibility + grounding.
• Q: Is it stiffer? A: Slightly (5-10 durometer points harder). We adjust the formula to maintain flexibility.
• Q: How do I measure conductivity? A: Multimeter for rough check; Volume Resistivity fixture for accuracy.
