Plant operators use polymer-grade propylene as the primary raw material and introduce ethylene as a comonomer during the reaction phase. High-performance catalysts drive the polymerization, followed by purification, flashing, drying, and pelletizing steps. The resulting block copolymer structure provides a distinct balance of stiffness and impact resistance.<\/p>\n<p>The extruded block copolymer delivers a highly controlled Melt Flow Rate (MFR) of 0.4\u00b10.1 g\/10min. Low MFR values indicate high molecular weight, giving the extruded material excellent structural integrity. Impact resistance remains high across temperature ranges, showing an Izod impact strength of \u2265250 J\/m at 23\u2103 and \u226525 J\/m at -20\u2103.<\/p>\n<p>Mechanical stiffness meets strict pipe manufacturing requirements with a flexural modulus of \u2265750 MPa and a tensile yield stress of \u226520.0 MPa. Pellet quality remains consistent batch-to-batch. PetroChina maintains strict appearance controls, limiting color and black speck particles to \u226410 pcs\/kg and off-size particles to \u226410 g\/kg.<\/p>\n<p>BASTONE Petrochem supplies KUNLUN PP DY-ZK0640P directly from PetroChina Dushanzi allocations. Direct access to China&#8217;s top petrochemical producers allows us to offer highly competitive pricing to global buyers.
