 abstract={<p>
 Growing emission requirements are forcing the foundry industry to seek 
 new, more environmentally friendly solutions. One of the
 </p>
 <p>
 solutions may be the technologies of preparing moulding and core sands 
 using organic biodegradable materials
 </p>
 <p>
 as binders. However, not only environmental requirements grow but also 
 those related to the technological properties
 </p>
 <p>
 of moulding sand. Advancing automation and mechanization of the foundry 
 industry brings new challenges related to the moulding sands.
 </p>
 <p>
 Low elasticity may cause defects during assembly of cores or moulds by 
 the manipulators.
 </p>
 <p>
 The paper presents the study of flexibility in the room temperature 
 according to new method and resistance to thermal deformation of 
 selfhardening
 </p>
 <p>
 moulding sands with furfuryl resin, containing biodegradable material 
 PCL. The task of the new additive is to reduce the
 </p>
 <p>
 moulding sands harmfulness to the environment and increase its 
 flexibility in the room temperature. The impact of the additive and the
 </p>
 <p>
 effect of the amount of binder on the properties of mentioned moulding 
 sands were analysed. Studies have shown that the use of 5% of
 </p>
 <p>
 PCL does not change the nature of the thermal deformation curve, 
 improves the bending strength of tested moulding mixtures and
 </p>
 <p>
 increases their flexibility at room temperature.
