New bicomponent binders for foundry moulding sands composed of phenol-furfuryl resin and polycaprolactone

Abstract

The aim of this article is to test the properties of foundry moulding sands with a new bicomponent organic binder. The new binder is the composition of phenol-furfuryl resin, commonly used in foundry practice and biodegradable material – polycaprolactone. The paper presents the research of strength properties, thermal destruction and thermal deformation of moulding sands with a new bicomponent binder. It was proved that inserting polycaprolactone to phenol-furfuryl resin did not lower the strength properties of tested moulding sands. The new additive did not affect the moulding sands thermal degradation but it changed their thermal deformation course.
