The 21st century is the electronic information age, the field of communication is expanding, with the continuous upgrading of electronic products and the continuous change of the consumer market, electronic equipment is gradually developing to smaller and thinner, “signal transmission” type of wire requires the wire diameter is getting smaller and smaller, so the wire used in electronic equipment also needs to be smaller and thinner. And a variety of fireproof high-temperature cables are also more and more application scenarios, requiring high-performance transmission cables must also meet the requirements of high frequency transmission performance and small flexibility on the basis of taking into account fire safety performance, and under the same impedance premise, if the wire diameter is reduced, smaller dielectric constant materials are required. Our conventional high frequency class (physical foaming, chemical foaming PE/PP) rubber foam the higher the foaming, the smaller the dielectric constant, so fluorine plastics came into being, with the upgrading of various electronic products and continuous change, “signal transmission” type of wire requirements wire diameter is getting smaller and smaller, in the high-speed transmission wire between 30~42AWG, Teflon material has been widely used for insulation; In order to require smaller or faster signal transmission rate on a small basis, it is necessary to use the Teflon foaming technology introduced today; Next generation high-speed transmission cable technology, Teflon foam.
In order to meet the requirements of fire resistance and transmission performance, physical foaming technology is necessary for fluoroplastic insulation, and the higher the degree of foaming, the smaller the cable core can be made, the less material and the better the transmission performance, the earliest fluoroplastic foaming equipment should be Switzerland Melafil Company, since 1995, through its cooperation with the famous American fluoroplastic DuPont, Developed and successfully designed a series of new patented technologies and corresponding equipment, so that the former fluorine plastic wire core insulation foam from the original about 50% in one stroke successfully reached about 65%, the current shipment of Teflon foam equipment to China’s equipment manufacturers are mainly Italy’s Rosentey and Switzerland Merafil, the main application scenario is CMP network cable production and foam medical line. There are only a few sets of equipment in China, and the value of the equipment is about 10 million yuan. After years of production practice has proved that the effect of saving materials is very significant, in order to meet the increasing safety performance requirements, the range of fluoroplastic foam materials is also expanding, more and more fire-proof performance and high frequency performance superior materials emerge, such as foamed PFA, foamed ETFE and other fluoroplastics. It can meet the requirements of various cable core manufacturing and different temperature resistance levels.
