Material Science is the science of structure, properties,
processing, and performance of materials.
Material Answers conducts projects encompassing all aspects
of material science and engineering. We have experience with
all major classes of materials: metals, polymers, ceramics,
glasses, and semiconductors.
Optimization of Ductility in Polyethylene/Rubber Blends
A blend of polyethylene and ethylene-propylene rubber
was being developed for an automotive application.
The blended resin exhibited erratic mechanical properties
associated with instabilities in the compounding process.

Quality in Ceramic Injection Molding
A ceramic injection molder experienced inconsistency in
the mechanical properties of parts molded from different
cavities in the same mold. Rheological testing of the ceramic
paste being molded resulted in the discovery of substantial
wall-slip during flow through small channels such as those in
the mold. Dependence of the wall-slip velocity on material and
process parameters was measured using capillary rheometry and
modeled mathematically. This enabled a more precise
balancing of the mold design and eliminated the
