DRM-P series graphene nanoplatelets pellets is a special graphene product for the modification of thermal conductive plastics, which is developed for the shortcomings of the traditional powder thermal conductive filler, such as difficult to feed, easy to pollute and small packing density. It has the characteristics of high thermal conductivity and easy feeding. It has very excellent thermal conductivity, the product is in the shape of particles/scales, suitable for plastic extrusion, injection molding, mixing, open smelting and other melt processing technology. The product has been treated by surface modification and has good compatibility with resin.
