TBA ECP 12E Stainless Steel Fiber Masterbatch EMI Shielding Thermoplastic
Categories: Metal; Ferrous Metal; Stainless Steel

Material Notes: ECP 12E is a stainless steel fiber masterbatch within an emulsion-based ethylene acrylic acid zinc ionomer binder, 25% by weight. It can be used with Styrenic Thermoplastics, PS,SAN, ABS also PPO and PPE Alloys, Polypropylene/Polyolefines. Other binders are available - ECP 16E using nylon 6/12 binder 25% by weight for use with nylon 6, 6/6, 6/10 6/12, PBT, PET. ECP 20E with a polycarbonate binder 40% by weight, for use with polycarbonate, polysulphone, PES, PET, PEJ, PBT. The masterbatch is added at very low levels ensuring minimal effect on color, moldability and other base polymer properties by 1% by volume. The use of this system allows EMI shielded articles to be produced in one process without additional equipment, labor or secondary processing and provides cost effective solution to EMI shielding problems.
