Static Dissipative Poly Tubing Saves Sensitive Electronics

Electrostatic discharge (ESD) as low as 100 electrostatic volts can damage electronic circuits, shortening equipment life. That’s why many manufacturers choose tubing that is specially formulated to prevent electrostatic buildup.
Made from ether-based polyurethane, Freelin-Wade’s static dissipative 90A poly tubing protects circuit boards and other sensitive electric components. We manufacture static dissipative ESD tubing using a proprietary polyurethane material, instead of adding metallic or carbon fillers that make tubing less flexible, increase creep, decrease memory, and make the tubing less resistant to abrasion. Our special compound allows for the static charge to be released very slowly, so as not to cause sparks (which are caused by quick or sudden flow of current through air). Additionally, the material does not become conductive. As a result, our static dissipative polyurethane tubing maintains its original properties and benefits.
Non-corrosive and ideal for use in high-tech applications, Freelin-Wade’s static dissipative ESD tubing is available a wide range of inch and metric sizes.

How Does Static Dissipative Tubing Work?

Static electricity is a stationary charge of electricity on the surface of an object. We most often associate it with that little shock we get on a dry day when we walk across a carpet and grab a metal doorknob. We experience it in lots of other places too, like when you pull a sweater over your head or a child rubs a balloon on their hair. What we are experiencing in these instances is electrostatic discharge (ESD). What you might not realize is that static charges can be generated in many other ways. Humans can only sense an ESD of greater than 3,500 electrostatic volts. The problem is that electronics can be damaged by an ESD as low as 100 electrostatic volts. The point being, you may touch something and think it’s safe when in fact it isn't.

Another thing to be aware of is that a charge may exist in one part of an object, but not in another. You can neutralize a charge in one spot of an object while a full charge remains in another area.
The size of the object holding the charge and that object's capacitance are key factors in how big of a charge the object can hold. Plastic is a good capacitor, and a run of tubing can be quite long. If the media in the tubing is dry, you may have a recipe for static electricity buildup. If the tubing is near sensitive electronics, this static charge may be a problem. It's for this reason that we developed our static dissipative polyurethane tubing.
