Effect of Modifiers on Injection Molding of Waste Polyethylene Drip Tape

Abstract

Abstract. In this work, effects of Ethylene-vinyl acetate copolymer (EVA) and Dicumyl peroxide (DCP) on injection molding of recycled polyethylene (PE) materials obtained from a waste disposable drip tape are studied. Under injected at 175-230°C and 35-40 MPa, the recycled PE materials with EVA showed good injection moldability, while those with DCP showed poor injection moldability with DCP introduction increasing. Under injected at 135-145 °C and 50-60 MPa, the recycled PE materials with DCP can be well injection molded.
