MDPE made via Spherilene
MD-3520 is a medium density polyethylene resin (MDPE), 1-butene co polymer, obtained by gas phase technology process. This grade designed for the production of drip irrigation tapes, pipes andmono or coex film applications. In this grade excellent processability combined with good mechanical properties. MD-3520 can be blended with different PE grades to modify the final properties of the products.
