【Range of application 】
Is suitable for various kinds of conductive, thermal conductivity, flame retardant materials, for all kinds of carbon black, carbon fiber, carbon nanotubes, thermal conductive ceramic powder, filler type flame retardant have certain polar filler has good affinity, can the very good dispersion, coupling activation, prevent the reunion, can obviously increase the efficiency of the conductive, thermal conductivity, flame retardant, improve liquidity and physical and mechanical performance, etc.
【Function characteristics 】
l Of inorganic filler with a strong affinity, make its are fully activate modification, destruction and prevent agglomeration of inorganic matter, which is more evenly dispersed in the polymer, thus can improve the addition amount of filler, at the same time rely on the strong interface key cooperation, to achieve the effect of toughening reinforcement.
l Used in the processing of polymer composites, can effectively improve the compatibility of system components, promote the plasticizing and lower melt viscosity, improve processing flow. And can improve the impact strength and elongation at break of parts such as mechanical performance, at the same time significantly improve product surface gloss.
l Because this product is highly reactive multifunctional group structure of anchor groups, through multipoint adsorption of the groups "anchor", at the same time for chemical reaction was carried out on the filler particle surface modification, achieve completely coated surface chemical reaction, make the organic filler surface, which can effectively reduce the surface of the packing, cut off between packing together. In twin-screw extrusion granulation process, the surface layer of exception handling stability, will not be the thermal mechanical force stripping, which makes its performance in the final product is far superior to the small molecules of coupling agent.
【Method of use 】
Can be directly mixed with powder, resin after joining in the twin screw extruder extrusion granulation.
Reference usage: for dispersion of powder packing weight 2-5%.
Such as the filler surface is processed in advance, the dosage is less, the effect best, will join the rest of the high-speed mixer stuffing, and then according to the packing of the weight of 1-2% to join the HD 502 modifier, mixing temperature is controlled in 100-110 ℃, high-speed mixing 10-15 minutes).
【Packaging storage and transportation 】
25 kg/bag (cowhide compound bag, lined with PE bag);
Please placed in dry, ventilated area, to avoid moisture and heat.
