Polypropylene drums: providing new opportunities within leather-making

摘要

After revolutionising the drum concept by introducing polypropylenernas a construction material in place of wood, new interesting projects destinedrnto make radical changes to the future of tanning are under investigation.rnPolypropylene is a semi-crystalline thermoplastic with high bonding strength. It is tough, stable, elastic, hard and highly impact-resistant. Due to its structure polypropylene has an exceptionally high molecular mass. This makes it highly resistant to chemicals and other media. Polypropylene is resistant to aqueous solutions of salts, acids and alkalis.
