Resins and PELESTAT are dry-blended
using a blender, such as a tumble mixer, and are molded
into the final product using an appropriate molder,
such as an injection molding machine and an extrusion
molding machine. Fillers and pigment may be added if
necessary in the dry-blending process.
When it is required to enhance the degree of dispersion
of components in the resins, knead the dry-blended compound
them and mold it. |

| As shown below PELESTAT has some hygroscopicity,
but is packed in bags under moisture proof conditions.
Therefore no drying is necessary, when PELESTAT is used
just after unsealing. If PELESTAT bag is kept open for
several hours after unsealing, drying is necessary;
or defective molding may occur. Determine the optimal
conditions for drying by referring to the following
data. |
