◆ Performance and scope of application ◆ 
 GK-7 is the internal intercalation of modified nano-montmorillonite, polyolefin, EVA, TPO; GK-7 has the ease of dispersion, particle distribution, does not influence the density of the resin. GK-7 dispersed into the resin to form a nanocomposite of its unique properties is to improve the mechanical properties of polyolefin materials, and no material impact properties decreased, and can effectively improve the flame retardancy of the material. 
 Applications: 
 Add the GK-7 nanocomposites mechanical properties, thermal properties, barrier performance has greatly improved and can be formed with the Department of phosphorus and nitrogen or phosphorus flame retardant compound, together to improve the flame retardancy. Added :2-15%. 
 ◆ use ◆ 
 GK-7 dispersion mixer, mixer and twin-screw extruder. 
 1, when used in polyolefins to join the polarity of the compatibility agent (grafted maleic anhydride, etc.), made Masterbatch, the best effect. 
 2, used in plastics can direct granulation, or common granulation and some flame retardants. 
 Steps: mix material --- twin-screw extrusion granulation - the masterbatch and particle blends --- together with the rest of materials and granulation.
