1. Difference between anti-static ESD foam and conductive ESD foam
IXPE conductive / anti-static foam: the product is extruded polyethylene or modified polyethylene and conductive filler and antistatic agent. After radiation crosslinking and high temperature foaming, conductive / anti-static foam plastics are made. Its surface resistance and volume resistance are 103-109 Ω, permanent conductive / antistatic, smooth surface, environmental protection, easy to be processed and molded, ESD foam are widely used in fields related ESD.
Characteristic:
1. Permanent conductive / antistatic performance;
2. Conductivity / antistatic performance is not affected by ambient humidity;
3. Volume resistance and surface resistance 103-109 Ω;
4. Easy for secondary molding.
The resistance of antistatic foam is 106 – 1011 Ω; The resistance of conductive foam is 103-109 Ω. Due to the difference of resistance value, the electrostatic half-life of conductive foam is far less than that of anti-static foam, and the electrostatic voltage of conductive foam is far less than that of anti-static foam; However, both can automatically release charge, and conductive foam is more suitable for electronic products with high electrostatic sensitivity.
2. Comparison of IXPE and EVA antistatic foam
In the normal range, IXPE and EVA are foamed after adding carbon black and mixing, and their properties are basically similar. IXPE has crusts on the surface anyway. EVA is molded foam, and the crusts are basically incomplete and the foam cells are fine. What is common is that they have been planed and cut by the manufacturer.
1. Conductivity, basically no difference
2. In terms of material properties, EVA is more wear-resistant, but it needs glue for forming and cannot melt self-adhesive. IXPE processing can be hot bonded without glue, which is more environmentally friendly;
3. There is basically no difference in weather resistance, temperature resistance, acid and alkali resistance;
EVA material is more suitable for lathe machining and forming, making backing plates on large electronic product lines, etc. make full use of its wear-resistant and weather resistant characteristics. Compared with EVA, IXPE foam is more suitable for making all kinds of forming pallets and knife cards. More importantly, EVA has better inclusiveness and can add a large amount of recycled materials. Therefore, EVA in the market now has a great taste, and IXPE is more environmentally friendly, Therefore, more large international companies choose IXPE conductive foam for anti-static products.
3. Application cases of antistatic IXPE conductive foam
IXPE conductive foam is a polymer conductive and anti-static foam made of polyethylene, foaming agent, high-efficiency conductive agent and other special fillers through radiation crosslinking and foaming. It has excellent conductive and anti-static properties. It is an ideal anti-static packaging material for optoelectronic devices, microelectronic integrated circuits, communications and so on.
Case 1: antistatic IXPE conductive foam insert
IXPE conductive foam has good antistatic property, stability and soft closed cell structure, which determines that this material can be used for plug-ins of electronic devices with pins; A conductive carton can provide perfect package transfer.
Case 2: antistatic IXPE conductive foam tray
IXPE conductive foam has good heat bonding processing performance and can be made into a tray with cavity. It is firm and durable and suitable for production line turnover, packaging and shipment.
