Abstract:
A light-weight molding material having a cream consistency. Even when a lightening material
has been added in a higher proportion, the molding material is excellent in flowability
which enables the molding material to be easily squeezed out through an orifice
of a given shape, and in shape retention which enables the molding material to
retain the given shape of the orifice at it is. It eliminates the problem of expansion, and
excellent storability is obtained. The light-weight molding material comprises a
binder resin comprising a polyvinyl alcohol resin, a viscosity modifier, water, and
a lightening material. The amount of the lightening material added is 3-22 wt.%
based on the whole molding material. The amount of the water added is 65-92 wt.%
