Polyethylene is a common thermoplastic resin typically used for injection molding applications. Polymers with densities ranging from .941 to .965 and over are considered high density. High Density Polyethylene (HDPE) has a high-impact strength with a higher operating temperature than LDPE. HDPE has excellent tensile strength, energy consumption, abrasion resistance, and resistance to stress cracks, and good chemical resistance and electrical properties. Injection-molded HDPE is resistant to warpage and distortion. FEATURES Excellent tensile strength Abrasion resistance Chemical resistance Excellent machinability Low coefficient of friction Self-lubricating Stress-cracking resistance Water/salt resistance Lightweight LIMITATIONS Poor heat resistance, high thermal expansion Relatively low physicals, can fail under high mechanical stress Soft surface APPLICATIONS Milk, juice, and water bottles Yogurt containers Margarine tubs Laundry products
