Braskem HDB0358 High-density polyethylene copolymer
Categories:	Polymer; Thermoplastic; Polyethylene (PE); High Density (HDPE); High Density Polyethylene (HDPE), Extruded
Material Notes:	HDB0358 is a bimodal high-density polyethylene copolymer grade. Offers an outstanding balance between stiffness, impact strength and Environmental Stress Cracking Resistance (ESCR), ideal for a wide range of blow molding applications. This grade is particularly well suited to chemical and detergent packaging as the exceptional ESCR can allow for significant bottle weight reduction. Applications: Packages, Small bottles, Blow molding of packages up to 25 L for chemical and household products, oils and food packaging, Sheets extrusion and Corrugated pipe extrusion. Processes: Extrusion Blow Molding, General extrusion. Test specimens from compression molded plaque according to ASTM D4703. Information provided by Braskem.
