Why Use Static Dissipative Hose?
Are you concerned about interior electrostatic build-up in your hose?
A conductive inner core of PTFE is required for applications where electrostatic potential can occur. The majority of materials serve as good conductors, allowing electrons to move back and forth, therefore, maintaining their equilibrium. However, some materials, including PTFE, are considered insulators, inhibiting the flow of electrons. This can result in static charge build-up on the surface of the PTFE. If this charge increases to a point exceeding the dielectric strength of the material, arcing could occur.
Potential electrostatic build-up inside a hose is influenced by a number of variables:
- The material being conveyed
- The velocity of the conveyed material
- The filtration and/or turbulence in the flow
stream - The humidity and temperature
Materials that are poor electrical conductors will typically possess the following inherent characteristics:
- Non-polarity (an imbalance between protons and electrons)
- Composition of non-mixable material, or a suspended solid (e.g. water and kerosene)
Some materials may be subject to electrostatic concerns, particularly at high flow rates or downstream of filtration.
