Polyurethanes (PUs) represent a family of useful synthetic polymers (thermoplastic or
thermosetting) obtained from diisocyanates and diols/polyols via polycondensation …

The ball-mill grinding (BMG) of polymers has a long history, starting with Staudinger
showing in the 1930s that polystyrene undergoes chain scission upon ball milling. However …

Polyurethane (PU) thermosets are usually landfilled at the end of their service lifetimes and
cannot be recycled through conventional means. Although dibutyltin dilaurate (DBTDL) is an …

Polyurethane foams (PUFs) are widely used in many different industrial applications
including automotive, construction, packaging, medical devices, thermal insulation …

Crosslinked poly (ethylene-vinyl acetate)(EVA) is extensively used in a wide range of
applications including solar cell encapsulates and athletic shoes. However, recycling large …

Polyurethane (PU) foams are a large volume commodity product and as such pose a
considerable recycling challenge for the polymer manufacturing industry. The incorporation …

Over the past decades, various industries shifted from traditional materials such as glass
and metals to thermoset polymers due to their excellent chemical resistance, thermal …

It is highly desirable to provide an effective methodology to recycle polyurethane foam (PUF)
wastes into similar or even higher value products, which is expected to promote the …

New biobased pentamethylene diisocyanate (PDI) trimers have received increasing
attention because of their high biochar content and excellent performance in coatings …

Introducing dynamic covalent bonds (DCBs) into polyurethane (PU) foams can solve the
problem of their poor recyclability. However, a dilemma arises between reprocessability and …
