Similar structure to Polyethylene with a much higher temperature resistance. Good mechanical properties and chemical resistance. More susceptible to oxidizing agents than HD-PE.
Polypropylene is highly resistant to chemicals and aqueous solutions of acids, alkaline’s and salts making it ideal for the manufacture of chemical storage tanks.
It has excellent impact resistance and a higher scratch resistance than Polyethylene. PP is also a food grade material, has excellent moisture resistance, a low coefficient of friction and is thermo formable, making it also ideally suited to food processing equipment and machinery.
CV Plastics has manufactured many products for marine applications from PP, battery boxes, bait tanks, and due to its excellent resistance to UV light it can be used outdoors for many years.
