1. The Danger of "Isolated Conductors"
Many factories use standard rubber or PVC sleeves and attempt to ground them using external copper wires or "jumpers." However, if the sleeve material itself is insulative, static charges can still build up on the inner surface, leading to a high-energy "brush discharge."

• The SOSHH Solution: Our PUAS material is permanently dissipative. This means the entire body of the connector acts as a safe path for static electricity to travel to the grounded metal flanges.
• Surface Resistivity: Verified at less than 10^9 Ohms, meeting the strict requirements of ATEX 2014/34/EU.

2. Eliminating the Need for "Grounding Wires"
External grounding wires are prone to breaking, corroding, or being incorrectly installed during maintenance.

• Simplified Safety: Because the SOSHH PUAS connector is inherently conductive through its molecular structure, it maintains electrical continuity across the joint.
• Zero Maintenance: You no longer need to worry about loose copper clips or broken bridge wires. The connection is safe the moment it is clamped into place.

3. Compliance with NFPA 652 and ATEX Standards
Global safety standards for combustible dust (such as NFPA 652 in the US and ATEX in Europe) require all conductive components in a "Dust Hazard Area" to be bonded and grounded.

• Zone 20, 21, and 22: SOSHH PUAS connectors are specifically designed for these high-risk zones, ensuring that even under high-speed powder flow, the charge buildup remains well below ignition thresholds.

4. Performance in "Black" vs. "Clear" Antistatic Materials
Historically, antistatic materials had to be black (carbon-filled), making it impossible to see the product flow.

• The SOSHH Innovation: Our PUAS series achieves high conductivity while remaining transparent. This allows your safety team to monitor for blockages or material accumulation while knowing the system is fully protected against static.
