Overview
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.

Problems Solved
Films or plastic processing applications lacking strength or sufficient binding properties Friction and increased strain rate due to lack of lubrication Lowered or inadequate viscosity that causes mechanical wear and leakage, increases thermal friction, and shortens the lifetime performance of the lubricant or grease Discoloration, such as bloom, streaking, or hazing, in tacky polymer processing
Applications
Automotive composites, plastic compounders, masterbatches, extruders, and molders Ceramics Fabrics and paper Greases, lubricants, and oils Water carbon filters Batteries
