In the search for materials to build more fuel-efficient
automobiles, lightweight yet robust plastic materials are
of great interest. Glass fiber-reinforced thermoplastic
polyurethane (TPU) is such a compound material. It can
be used for a range of applications where greater structural
integrity is required, such as in automotive body side
moldings and other automotive components.
Of course, the amount of glass fiber in the processing
mixture affects the integrity and quality of the final product.
That means variation among batches of raw materials can
lead to a high rejection rates of manufactured product,
which is especially expensive when injection molding large
parts or processing on large extruders. So it’s important
to understand the quality of batches of raw materials,
such as TPU, early in the process.
