Features of electromagnetic shielding silicone sealing strip products

  Electromagnetic shielding silicone sealing strip is a newly developed product, which has three major properties of conductivity, shielding and sealing, and is mostly used in 5G communication construction equipment. The conductive agent is mainly added to the raw material of silica gel, and this conductive agent is not directly molded and extruded together with silica gel. The electromagnetic shielding silicone sealing strip is a sealing product, and the silicone extrusion process is infinitely long and needs to be cut and bonded. The glue that needs to be used directly for bonding is also a glue that must be specially treated. If you use ordinary silicone glue It will cause the product to be non-conductive and have no shielding effect, but it has sealing performance. After bonding, the side sprayed with conductive agent faces the inside of the communication equipment, and the side not sprayed with conductive agent faces outward for sealing, so that one product can have three effects.
  Product features of electromagnetic shielding silicone sealing strip: 1. Good electromagnetic shielding effect, a special treatment agent is added to the extruded silicone product to make it have electromagnetic digestion and shielding specific reception.
2. The product has a very low physical quantity of material resistance characteristics, (silver/aluminum 0.004Ω*cm, ratio of resistance to cross-sectional area*length) (nickel/carbon 0.02Ω*cm), the lower the resistivity, the better the effect.
3. Longer service life (platinum inert vulcanization effect)
4. Electromagnetic shielding silicone sealing strip has good sealing performance of ordinary sealing strips . Silicone has always been the first choice in the field of sealing strips.
5. Temperature resistance. Silicone has the characteristics that other materials cannot replace, that is, it has excellent high and low temperature performance - it can work for a long time between 40 and 200° without affecting its electrical conductivity.
