Description

What is Stabilant 22? Stabilant 22 is an electrically active material which stays resident within a contact-pair, there enhancing conductivity without causing electrical leakage between adjacent contacts. Although Stabilant 22 does have a detergent action it is not sold as a cleaner, just as it has a good lubricant action but is not sold as a lubricant. Stabilant 22 is used to increase the reliability of contacts. Tenfold to one hundred-fold increases are not unusual. At the present time it is used in many different types of contacts, including card-edge connectors, D-type connectors, MIL-spec connectors, signal switches, etc.Stabilant 22 is an initially non-conductive amorphous-semiconductive polyoxyethylene-polyoxypropyline block polymer with a molecular weight of about 2800 that, when used in thin films between contacts, acts under the influence of the electrical field and switches to a conductive state. The electric field gradient at which this occurs is established during manufacture so that the material will remain normally non-conductive. Its switching speed is too slow to allow it to be used in the more traditional semiconductor applications; however, this means that signals at frequencies substantially above five cycles per hour will not be modulated by the switching characteristics of Stabilant 22.Thus, when applied to electromechanical contacts, Stabilant 22 provides the wide-bandpass connection reliability of a soldered joint without bonding the contacting surfaces together! In its undiluted form at room temperature, Stabilant 22 has the viscosity of medium-weight motor oil, although it thins out with increasing temperature, starting to decompose into the two polymers it is formed from at about 240° Celsius. It has a very low vapor pressure and therefore there is no appreciable loss of material from evaporation. It has been in some applications for more than fifteen years without renewal, and it is probably safe to say that in the majority of cases, the
