3 4270 series electrically conductive connector covers conductive composite 3m 4270 series connector covers feature a new unique conductive composite material. the material is made intrinsically conductive by uniformly distributing a conductive matrix of fibers during compounding. the covers are permanently volume conductive and free of carbon black particulate. the 4270 series covers do not leave black marks and are more suited to clean situations. noncorrosive 4270 series connector covers are noncorrosive and produce no visible corrosion when tested to federal test method 101c using kovar test plates. property test method typical value resistivity astm d991 <10 5 ohm-cm contact corrosivity ftm 101c pass metod 3005 (kovar plate) crayoning 3m not visible elongation astm d638 25% tensile astm d638 1500 psi vicat softening astm md 1525 96 o c out gassing astm e595 pass material properties chemical reactions dilute acids slight attack dilute alkalines slight attack concentrated acids severe attack concentrated alkalines severe attack methanol, ethanol, and isopropanol resistant hydrocarbons slight attack ketones dissolves oil and gasoline severe attack chemical susceptibility military application 4270 series circular connectors covers were designed to meet the requirements and intentions of ms90376, and mil prf 5501/31a or 32a. prominent military contractors have qualified these materials to their own specifications and are encouraging their use. conformability the material used in the covers were also selected for its resilience. properly sized, the covers provide a snug, secure fit. this helps keep connectors clean and prevents the cover from accidentally falling off.
