Is plastic electrically conductive? Yes. Although we learn in school that plastic is a good insulator and sheaths for power cables are often made of plastic, electrically conductive polymers have nevertheless recently appeared on the market, used for three-dimensional or foldable displays in the field of printed electronics, among other things. Special properties of these materials are sufficient mechanical flexibility. Conductive polymers, also called intrinsically conductive polymers, are plastics with electrical conductivity. This contrasts them with normal polymers, which are non-conductors. The conductivity of the polymer is achieved by conjugated double bonds, which allow free mobility of charge carriers in the doped state. Conductive polymers are basic materials in organic electronics and are used in liquid crystal displays and OLED displays, as well as in organic photovoltaics. Filtration Group Industrial’s customer, a technology group in Hanau, Germany, produces touch-sensitive touch panels. The polymer material is used as an electrode in touch screens and printed electronics.
Filtration Group Industrial’s customer has a large portfolio of materials and technologies for printed electronics. In the filtration of polymer solutions, the automatic backwash filter used by Filtration Group Industrial provides reliable cleaning of the filter surface by temporary or partial flow reversal. The previously used solution via a 3-stage cascade was very complex and cost-intensive. In order to achieve the required filtration quality, separation was carried out via a filter bag, a filter cartridge and a modular filter.
Info
Positive side effect: Previously, silicon and aluminium components were dissolved into the cascade from the filter modules, and this may affect the performance of the polymers. The use of FG’s technology enabled the concentration of aluminium and silicon to be reduced to 0.00 ppm.
The AF 173 test filter that is used features pulsating external pressure segment cleaning in a continuous filtrate flow, and it provides automatic cleaning of the filter elements and back-flushing with demineralized Water
Less space required: previous filter solution requires considerably more operating space than the FG test filter that is used
