RAPREX R-300 Sterigenics Polyethylene, Linear Low Density

Product Description

RAPREX® R-300 is a linear low density polyethylene based resin that exhibits an excellent balance of melt processability and physical properties due to its unique branched structure. It is a thermoplastic and is recyclable. Due to its high molecular weight and melt strength, RAPREX® R-300 is used in film applications where enhanced puncture and tear resistance is required. Because of its high melt strength, it is also used in the production of low density foams. Raprex® R-300 contains a robust stabilization package providing excellent melt stability as well as long-term heat aging.
