Thermo-physical and impact properties of epoxy containing epoxidized linseed oil, 1 - Anhydride-cured epoxy

Biobased neat epoxy materials containing epoxidized linseed oil (ELO) were processed with an anhydride curin- a-ent. A defined amount of the diglycidyl ether of bisphenol F (DGEBF) was replaced by ELO. The selection of the DGEBF, ELO, and an anhydride curing agent resulted in an excellent combination, to provide a new biobased epoxy material showing high elastic modulus, high glass transition temperature, and high heat distortion temperature (HDT) with larger amounts of ELO. The Izod impact strength was almost constant while changing the amount of ELO. This is a promising result for future industrial applications in different engineering industries.
