SILVET® 420-30-E1 Aluminum Pigment


SILVET 420-30-E1 is a very coarse particle size, bright aluminum glitter pigment produced in pellet form to reduce the potential for generating airborne particles and to improve ease of handling. The pellets are composed of 70% aluminum pigment carried in 30% polyolefin and are produced by a low shear process for easy dispersion. This grade can be used to simulate metallic effects similar to those of 200 microns by 200 micron chopped foil pigments. This grade has a very narrow particle size distribution and will produce coarse glitter effects when used alone or with chromatic pigments or dyes. Due to its narrow distribution range this grade can be used to create metallic effects with minimal flow line appearance.

-Glitter flake grade

-Granular form

-Coarse, thick aluminum flake



SILVET E1 grades are easy to disperse and are compatible with a variety of polymers, particularly polyolefins. They are typically used to make concentrates or compounds for use in final processing by injection molding, extrusion, blow molding or blown film processes. In some cases SILVET E1 can be used directly in end-use processing but care must be taken to ensure complete dispersion is achieved. Their pellet or granular form make them easy to handle and incorporate.

It is normally sufficient to tumble blend the pellets with the base resin and any additional colorants or additives before processing. Incorporation techniques should not subject the flakes to high shear forces.


Aluminum pigment should be stored in the original shipping container and kept tightly sealed. Store containers in a cool, dry, well-ventilated, and properly rated area. Avoid any conditions that will suspend or float the particles in the air, creating a dust cloud. Avoid all possible sources of ignition. For additional information, please refer to the Safety Data Sheet (SDS) for this product, available from Silberline upon request. An SDS is supplied with all samples of this grade.
