LyondellBasell Microthene® GR 542-00 is an EVA-powder additive used to improve the product finish for various polyolefin and composite resins by enhancing flow and improving surface appearances.
LyondellBasell Microthene® GR 542-00 is an ethylene vinyl acetate (EVA) powder additive designed for specialty applications. Microthene® GR 542-00 polyethylene technology comes in powder form and is ground, irregularly- shaped particles for a broad range of specialty applications. Microthene® GR 542-00 combines the unique properties of a polyolefin resin with a small-ground particle size as a low-profile additive for fiber-reinforced plastics. GR 542-00 can help improve surface smoothness while controlling shrinkage caused by various plastic molding processes.
