Vulcanised rubber
Polypropylene
Solution
Vulcanized rubber
A cross-linked polymer made by chemically treating rubber with sulfur to create a three-dimensional network of polymer chains. This process is called vulcanization. The cross-links make rubber stiffer and more elastic, and give it mechanical robustness, thermal stability, and chemical resistance.
