Resin has been around a long time too. As far as I know, resin requires a catalyst or excellerator to harden and it gets very hard. Some resins can harden when exposed to air, but this takes days. The hardening process is not reversible. Styrene moldings are made by softening pellets and forcing it into the mold. It hardens with temperature and can be returned to a liquid state by adding heat.mapep said:What is the basic difference between resin and styrene? Which would be better for buildings? Which would be better for railroad rolling stock. I realize styrene has been around a while, but I know very little about resin and its uses.![]()
