UNIVAL™ DMDC-6150 NT 7高密度聚乙烯(HDPE)树脂是一种分子量分布广、分子量大的聚合物。该产品具有良好的挤出性和型坯稳定性,有助于大零件壁厚均匀。UNIVAL™ DMDC-6150 NT 7高密度聚乙烯树脂是吹塑容器的理想选择,如5-55加仑(19-212升)封闭式集装箱和其他类似部件。分布广泛,在刚性好的情况下,具有优异的抗环境应力开裂性能。由于这些特性,各种产品,如工业化学品、乳胶漆、印刷油墨、食品、粘合剂和其他化学特性,可包装在由这种树脂制成的容器中。对于高质量的应用,模件的光滑表面易于处理和打印。主要特点:优良的环境应力抗裂性、优良的型坯熔融强度/低凹陷性、良好的挤出性/加工性、良好的刚性符合:美国FDA 21 CFR 177.1520(c)3.2A加拿大HPFB无异议(有限制)请参阅相关法规了解完整细节。 UNIVAL™ DMDC-6150 NT 7 High Density Polyethylene (HDPE) Resin is a polymer with broad molecular weight distribution and high molecular weight. This product provides an excellent combination of extrudability and parison stability, which contribute to uniform wall thickness in large parts. UNIVAL DMDC-6150 NT 7 HDPE resin is ideal for blow molding containers such as the 5-55 gallon (19-212 liter) closed head shipping containers and other similar parts. The broad distribution also provides outstanding environmental stress crack resistance (ESCR) at a good rigidity. Because of these characteristics, a wide variety of products, such as industrial chemicals, latex paints, printing inks, foodstuffs, adhesives, and other chemical specialties may be packaged in containers produced from this resin. The smooth surface of molded parts is readily treated and printed for high quality applications. Main Characteristics: Excellent environmental stress crack resistance Excellent parison melt strength/low sag Good extrudability/processability Good rigidity Complies with: U.S. FDA 21 CFR 177.1520 (c) 3.2a Canadian HPFB No Objection (With Limitations) Consult the regulations for complete details. |
