Application: The combination of low-density graphite powder and conductive nickel layer forms a lightweight filler, which is very suitable for conductive gaskets (extrusion molding, mold molding, sheet and field molding) and sealing rings. Other uses include: plasma spraying, friction products and carbon aluminum.
1. conductive silicone rubber products, containing conductive gaskets, conductive rubber plates, rubber strips, etc., such as conductive zebra strips.
2. Conductive fillers of acrylic tape, including pressure sensitive conductive tapes with metal sheets as gaskets. Fabric conductive tape based on foam cotton, unlined conductive tape
3. conductive adhesive;
4. conductive paint, conductive film;
5. conductive ink;
6. substitute for silver and nickel powder.
Advantages: There are many varieties of conductive fillers for silicone gaskets, from carbon black, conductive nickel-coated graphite powder, silver-plated materials (AgAl, AgNi, and AgGlass) to pure silver. Compared with other competitive materials, conductive nickel-coated graphite powder has advantages in the following three important aspects:
Shielding effectiveness: The shielding of conductive nickel-coated graphite powder is significantly better than carbon black, slightly inferior to pure silver, but comparable to silver-plated materials. Published data shows that the shielding effectiveness of conductive nickel-coated graphite powder is comparable to silver-plated materials in a wide frequency range.
Electrochemical corrosion: Many enclosures that require conductive gasket protection are aluminum products. Silver and silver-plated fillers can produce electrical coupling and accelerate the corrosion rate of outdoor products. Nickel and aluminum housings are very compatible.
Cpmpetitive Price: The price of conductive nickel-coated graphite powder is only 1/3 to 1/4 of silver-plated materials, which is much cheaper than pure silver.
