Coreflex LLC Is Proud To Announce The Availability Of Conductive Innercore On Our Hoses Of Teflon®

A conductive innercore of Teflon is required for applications whereby, static discharge can occur. The majority of materials serve as good conductors, allowing electrons to move back and forth, therefore, maintaining their equilibrium. On the other hand, some materials are considered insulators, which prevent this flow from happening. The result…a charge, built up on the surface of the Teflon innercore. This charge may exceed the dielectric strength of the material, subsequently causing a leak, or even an explosion! Materials with a resistivity greater than 108 Ω are considered ‘nonconductive' (i.e. fuels).
The potential hazards caused by these materials can be neutralized with Coreflex's new conductive, Teflon innercore. During the manufacturing process, carbon is added to the PTFE, allowing a maximum resistance of 106 Ω, when inducing a charge of 500 volts, direct current. The carbon additive allows the electrostatic charge to convey through the Teflon innercore, directly to the
metallic end connections, ultimately preventing a charge from building up.
Materials that are poor conductors of electricity will typically possess these inherent characteristics:
1) Non-polarity (an imbalance between protons and electrons)
2) Composition of non-mixable material, or a suspended solid (i.e. water and kerosene)
The electrostatic build-up inside a hose will be influenced by a number of variables: (i) the velocity of the conveyed material, (ii) the material being conveyed, (iii) filtration and/or turbulence generating members in the flow stream, and (iv) humidity and temperature. Materials that may be subject to electrostatic concerns (particularly at high flow rates or downstream of filtration include:
