Description
Mohammad Mirhosseini and Reza Khordad studied how an additive changes cast polyurethane rubber in a 2025 paper. Five mixes were made with the additive, propylene carbonate, at levels from none to twenty percent by weight. The cure ratio stayed fixed so the additive's effect stood alone.
As the additive rose, hardness fell step by step, which points to looser links between chains and freer chain motion. Spring-back rose from under a third to nearly half, and stretch grew while pull strength dropped. Wear loss also fell with more additive. At high levels the rubber behaved more like a soft elastic. The authors present the additive as a cheap, simple knob for tuning this rubber for many uses.
