Influence of thermomechanical relaxations on the impact strength of polyethylene

Research output: Contribution to journalConference article

Abstract

The influence of thermomechanical relaxations on the impact behaviour of rotationally moulded polyethylene is presented in this paper. Four grades of polyethylene: two linear low density and two medium density, are considered. Impact tests carried out over a temperature range -50 °C to +30 °C indicate a maximum value of impact strength at -10 °C for three of the materials tested, and at -30 °C for the fourth material. Dynamic mechanical thermal analysis of each material shows a slight increase in viscous modulus at a temperature corresponding to that at which maximum impact strength occurs.
