TH21339B - Polyacetal composition with conductive condition - Google Patents

Abstract

DC60 (15/01/41), polyacetal composition with an electrically conducting condition. Which offers flexibility and Improved durability And the ability to process processes And being a good flow condition. Composition consists of oxymethylene polymer. Elastomer, polyurethane and carbon black with an electrically conducting condition. With a lower structural level (DBP absorption) and large particle size (low surface area) than the previously mentioned conductive carbon black used in the composition. The constituents were composed of between approximately 65 and approximately 85 percent by weight. Oxymethylene polymer, between approximately 10 and 20 percent by weight Elastomeric polyurethane Conductive carbon black has a BET surface area (N2) of between approx. 40 and approx. 100 m2 / g and a small pore volume, DBP absorption, between approximately 150 and approximately 350 ml / 100. Conductive Carbon Black Has been used in this element Spreading More easily in the polymer of the composition. And any diminished increase in molten viscosity during compounding Polyacetal elements with an electrically conducting condition Which offers flexibility and Improved durability And the ability to process processes And being a good flow condition.
