Stress Cracking of Polyethylene in Organic Liquids.

Abstract

The following results have been obtained: Fracture mechanics is applicable to both high and low density polyethylene at low and intermediate stress intensity factors. Constant crack speed was found to increase with detergent concentration up to 25% Igepal C0-630. William's flow model was found to be inadequate to describe crack propagation. An aggressive environment, which has micellar solution structure, was found to be effective in cracking compared to the one having nonmicellar structure.
