The Effect of Phenolic Regrind on the Mechanical Properties of HDPE

摘要

The possibility for recycling cured phenolic material was evaluated by testing mechanical properties of High-Density Polyethylene (HDPE) containing phenolic regrind material. The mechanical properties evaluated were: modulus of elasticity, percent elongation, tensile strength, and impact strength. Four different levels of phenolic regrind were used for evaluation with four different levels(4.76, 9.09, 16.7%) of phenolic regrind used in the comparison. The results demonstrated that with higher levels of phenolic regrind in the base HDPE material, certain mechanical properties degraded, with increased brittleness the most apparent effect.
