| Lupolen 4261 AG BD is a high molecular weight high density polyethylene (HDPE). Typical customer applications include automotive fuel tank applications if outstanding biodiesel durability is requested. It is supplied in pellets and is stabilized with antioxidants for the extrusion process. The product features an outstanding Environmental Stress Cracking Resistance (ESCR), good chemical resistance in combination with an excellent low temperature impact resistance. Typical processes include blow molding and thermoforming. Physical properties and process ability are very close to Lupolen 4261 AG. Lupolen 4261 AG BD is not intended for use in medical and pharmaceutical applications. The product can not be used for food contact applications.&& |
