Why does a material, intended for luxury handles, scratch? Or why is a black
plastic shiny when it's supposed to be used to make matt-black dashboards?
Products can go wrong in ways that are sometimes obvious at a glance. This is
plainly not acceptable: customers want what they've paid for.
Why is a plastic wrap, designed as tasteless and odourless packaging to keep
meat products fresh, delaminating? The producer wants clarity: the material
has to meet statutory standards. Our investigation homes in on irregularities.
In consultation with the customer, we determine our strategy and select the
right combination of techniques.
This is the kind of issue that DSM Resolve investigates. Sometimes the answers
turn out to be surprisingly straightforward - the wrong material has simply
been used. On other occasions, the solution is found in a modified process,
different quantities, better mixing or an adjustment in processing
temperature.
The approach is similar when plastics are found to contain particles of
contaminant, undissolved material, gels or pits. A variety of analysis
techniques, including microscopy, Raman spectroscopy and IR give us the
chemical and physical information we need. We localize and analyze, steadily
zooming in on potential causes.
