HIGH TEMPERATURE PLASTICS | MATERIALS
with many electronic components requiring surrounding materials to protect them against electrostatic discharge (ESD), it has developed a new ESD grade based on its GAPEKK material with a relatively low melting temperature (Tm is 305°C). The grade, GAPEKK 6-3200G ESD, is a nano- composite containing multiwall carbon nanotubes with a surface resistivity in range of 106
to 109 Ω. It
can be used for extrusion and 3D printing as well as injection moulding. An additional advantage, according to Jaimin Zaveri, DGM for Marketing and Application Development, is that it has superior elongation: 51%, which is way in excess of many aryl ketone compounds containing carbon fibre. Turkish compounder Eurotec says it aims to play an active role in using high performance thermo- plastics to produce new solutions. PPAs, PEEK, and polyaryl sulfones (PES, PPSU, PSU) are included in the product line under the brand names Tecomid HT, Tecopeek PK and Tecotek ES, Tecotek EP and Tecotek EU, respectively. Tecomid HT and Tecotron can provide continu- ous-use temperatures (CUT) up to 180°C and 210°C. One grade, TecomidNT40 GD40 BK009 XA61 (PPA, 40% glass fibre reinforced, flame
Very Long Fiber Compounds show superior impact resistance when compared to short fibre compounds based on the same polymer Source: RTP
retardant and heat stabilised), was approved by an automotive OEM for a new generation of inverter housing application where standard PBT and PET materials cannot provide the required CUT. Several high performance polymers have
inherent flame retardant behaviour, which allows them to meet stringent standards relating to heat
