  • Helping the Flow of Materials Information
    Acoustic insulating polyamide Rhodia Engineering Plastics, Lyon, France, launches Technyl Star S 218dB1 MSO and 218dB2 MV60, two new polyamide grades that provide more than 4 dB improvement in acoustic insulation over other engineering plastics such as glass-reinforced PP or PA.
    The US company Imi�?Tech says that its Solimide lightweight insulating polyamide foam weighs as little as one�?quarter as much as alternative approaches to acoustic /thermal insulation , which can result in reductions ranging from 30t on a frigate to 200t aboard an aircraft...
  • Space charge accumulation in coating materials for motor windings under DC high voltage
    Therefore, in this report, we have investigated the space charge behavior in polyamide -imide(PAI) and polyester-imide(PEI), which are usually used as the coating insulating materials for motor windings, under DC high voltage using PEA(Pulsed Electro- Acoustic method) method.

  • Optical imaging of shock waves produced by a high-energy electromagnetic transducer
    To prevent breakdown,the coil was wound from high-punty copper conductor insulated with a tough two-layer enamel (polyester/ polyamide -imide),giving it an extremely high insulation resistance. The acoustic backing was a circular disc ground from 16mm thick float glass with a central hole...
  • Use of wet�?laid techniques to form flax�?polypropylene nonwovens as base substrates for eco�?friendly composites by using hot�?press molding
    polyamide -PA, polylactic acid-PLA, polycaprolactone-PCL, poly- hydoxibutyrate-PHB, etc. [8–11] could lead to eco- friendly composites with interesting properties such as balanced mechanical behavior, cost effective materials, easy processing by conventional extrusion and injection molding, thermal, and acoustic insulation , etc. [12].
