Постоянный антистатический полистирол соэкструдированный листовой рулон стр.

To polymer materials in accordance with its beautiful appearance, low price, excellent electrical insulation properties, good processability and chemical resistance and wide application. But the accumulation of electrostatic when friction, causing surface dust, closing film, electronic device breakdown, such as electric shocks and explosive many disasters. To eliminate electrostatic hazards, the industry generally limit material ground surface resistivity in 1012Ω. Under the low molecular weight antistatic agent is added in the polymer base material is the most commonly used in anti-static measures, mainly due to the modified materials using antistatic agent in the material surface adsorption of water to reduce surface resistivity, therefore, the durability is poor, not washable, dependency to environmental humidity is big, and material heat-resisting temperature and surface properties have different degree. The black carbon, metal filler modified polymer, although won the permanent antistatic performance is good, but prices are high, it is not easy coloring, packing is easy to fall off, or oxidation and a decline in physical properties, such as faults. RTCrpUDGiTSince the 80 s, foreign successively developed a series of hydrophilic polymers, and ABS resin, HIPS and PMMA hydrophobic polymer blends, the permanent antistatic polymer alloy. Permanent antistatic alloy not only better keep basic performance and the matrix polymer and humidity in mechanical friction and relatively wide range showed good and stable antistatic ability. Therefore, to this kind of hydrophilic polymer called permanent antistatic
