A highly conductive thermoplastic elastomer (TPE) gap filler having superior durability and EMI shielding properties. According to the preferred embodiment, the TPE comprises graphite fiber having a nickel-copper-nickel coating formed thereabout that is suspended within an elastomer, which preferably comprises polyvinylchloride (PVC). The TPE of the present invention is particularly well-suited for reducing radio frequency electromagnetic radiation reflected by gaps formed between adjacent panels of a structure, and is particularly well-suited for the ma...


[ What is claimed is:] [1.]1. A method for reducing radio frequency electromagnetic radiation reflected by a gap present between adjacent panels of a structure, the method comprising:a) applying a gap filler to substantially fill said gap present between adjacent panels of a structure, the gap filler comprising:i) a thermoplastic elastomer matrix;ii) a plurality of conductive fibers dispersed within said matrix, said conductive fibers comprising coated graphite fiber having a first layer of nickel radially deposited thereabout, a second intermediate laye...
