Long Stainless Steel Fiber Filled Polycarbonate/ABS Material  (6 wt% stainless steel fiber fiber)  Celstran® PCABS-SF6-05 AF3005 NATURAL is composed of a polycarbonate/ABS polymer matrix with 6 wt% stainless steel fiber. Celstran®Â long stainless steel fiber filled PC/ABS materials provide electrical conductivity needed to reach desired levels of electrostatic dissipation (ESD) and electromagnetic interference (EMI)/radio frequency interference (RFI) shielding. These materials have significant advantages over short stainless steel fiber filled plastics. Conductivity properties increase by nearly 100 times when comparing to similar loadings. Celstran®PCABS-SF-05 materials contain continuous stainless steel filaments wetted and encapsulated by PC/ABS resin. Various stainless steel loadings can be selected to meet specific end use requirements.
