Polypropylene adalah polymer hidrokarbon linear dan salah satu polymer paling serbaguna yang tersedia. Polymer ini dapat diubah melalui proses polimerisasi. Ketika dipolimerisasi dengan ethylene, struktur rantainya berubah, meningkatkan kekuatan benturan dan ketahanan. Dengan sifat yang beragam, grade ini sangat cocok untuk berbagai aplikasi seperti films, injection molding, thermoforming, extrusion, dan blow molding processes.
