ECP 12E EMI Shielding Thermoplastic Stainless Steel Fibre Masterbatch
ECP 12E is a stainless steel fibre masterbatch within an emulsion-based ethylene acrylic acid zinc ionomer binder, 25% by weight. It can be used with Styrenic Thermoplastics, PS,SAN, ABS aslo 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 colour, mouldability 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, labour or secondary processing and provides cost effective solution to emi shielding problems.
- No secondary process
- Used in any plastic moulding application
- Can be coloured (but not suitable for bright colours such as yellow, white etc)
- Provides shielding of 50dB attenuation
- Cost effective
- Minimal effect on colour
- Eliminates secondary emi shielding process
- A masterbatch pellet
- Stainless steel fibre AIS1304, bonded with polymer specific binder
- In pellet form, 5mm chopped length
Shielding effectiveness measured using shielded room test MIL STD 285 - 3mm thick plaque. 1% volume steel fibre.
