Examid PA12 CF30<\/strong> — an injection-molding<\/strong> polyamide 12 compound reinforced with 30 % chopped carbon fiber<\/strong> (PAN-based, not a structural CFRP prepreg). It combines the lowest water absorption in the entire polyamide range<\/strong> (~0.25 % in 24 h at 23 °C), electrically conductive behavior<\/strong> imparted by the carbon-fiber filler, high dimensional stability in humid environments and good chemical resistance to oils, fuels and alkalis. Processed by standard injection molding at a melt temperature of 240–270 °C; mold temperature 80–100 °C; preferably uniform filling, since carbon fiber tends to orient along flow lines and cause shrinkage anisotropy.<\/p>\n Unlike static-dissipative (antistatic) grades (surface resistance 109<\/sup>–1012<\/sup> Ω\/sq), PA12 CF30 falls within the electrically conductive range<\/strong>: typical volume resistivity 101<\/sup>–104<\/sup> Ω·cm<\/strong>, surface resistance 102<\/sup>–105<\/sup> Ω\/sq (per ISO 3915 \/ IEC 60093). This allows the compound to be used where simply “not accumulating” charge is not enough — for reliable static drainage and current dissipation in ATEX zones, housings of ESD-sensitive electronics, and assemblies in contact with light hydrocarbons. The exact resistance depends on fiber orientation within the part — in weld-line zones and thin walls it can be 1–2 orders of magnitude higher.<\/p>\n Automotive:<\/strong> fuel systems (assemblies with electrostatic drainage), quick-connect fuel line couplings, pressure and temperature sensor housings, brake system components, brackets.<\/p>\n Aerospace (secondary structures):<\/strong> cable routing brackets, harness holders, connector and backshell housings, cabin air duct guides, auxiliary sensor housings. Not intended<\/em> for skin panels or load-bearing structural elements.<\/p>\n Oil and gas, ATEX:<\/strong> housings of portable instruments for explosive atmospheres, downhole connectors, protective covers for cable glands, pump components in hydrocarbon media.<\/p>\n Electronics and instrumentation:<\/strong> housings of ESD-sensitive devices, PCB holders, chip shipping containers, wafer-handling guides.<\/p>\n Industrial robotics and UAVs:<\/strong> lightweight load-bearing manipulator links, servo drive housings, drone frame components wherever stiffness plus ESD protection is required.<\/p>\n Medical and sports:<\/strong> positioners for X-ray diagnostics (low radiation absorption), orthosis and prosthesis components, frames and fittings for high-end carbon-composite bicycles.<\/p>\n Comparable grades in the portfolios of leading manufacturers: Evonik Vestamid L-CF30<\/strong> (PA12, 30 % CF), Arkema Rilsamid AECTL\/Rilsan PAECTL<\/strong> (PA11\/PA12 + CF), EMS-Grivory Grilamid LV-3CF<\/strong> (PA12 + 30 % CF), RTP Imagineering Plastics 200 AR series<\/strong> (PA12 + CF). Examid PA12 CF30 is offered as a technologically and parametrically comparable localized alternative with flexibility in logistics, minimum batch size and property customization on request.<\/p>\n The stated values are measured using in-house methods close to the corresponding ISO and GOST standards.
