Technical Details & Test Data
- Material Specification
- A masterbatch pellet
- Stainless steel fiber AIS1304, bonded with polymer specific binder
- In pellet form, 5mm chopped length
- Shielding Data
Shielding effectiveness measured using shielded room test MIL-STD 285 - 3mm thick plaque. 1% volume steel fiber.
- Binders
Other binders are available - ECP 12E using Emulsion based ethylene acrylic acid sinc ionomer binder, 25% by weight for use with Styremic Thermoplastics, PS, SAN, ABS, also PPO and PPE Alloys, Polypropylene/Polyolefines. 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, mouldability and other base polymer properties by 1% by volume.
The use of this system allows shielded articles to be produced in one process without additional equipment, labor or secondary processing and provides cost effective solution to EMI shielding problems.
