Polypropylene PP a good choice for mechanical and structural applications such as plastic water tanks.
POLYSTONE®P PP-H polypropylene is one of the most cost effective and widely used general purpose EPP’s available. It is a stiff and hard polyolefin, with high heat resistance and excellent chemical resistance at elevated temperatures. Used extensively in the chemical process industry it is also highly resistant to aqueous solutions of salts, acids and alkalis. POLYSTONE®P PP-H can be readily formed with excellent toughness at room temperature.
It is an easily weldable thermoplastic which makes it ideal for tanks, fittings and vessels for the mineral processing, mining and galvanizing industries. Has very low permeability to water vapour and gasses.
