Polypropylene Sheets & Rods

Polypropylene is noted for its excellent chemical resistance in corrosive environments. Polypropylene Homopolymer (PPH) possesses excellent resistance to organic solvents and degreasing agents as well as electrolytic attack. PPH sheet is harder and has a higher temperature resistance than HDPE but lower impact resistance and becomes brittle below ~0C. Hence like polyethylene's, polypropylene has good chemical but poor UV resistance (unless stabilised or protected).

Polypropylene copolymer (PPC) grades are preferred for all applications exposed to cold conditions. These copolymers have better impact strength, maintained down to lower temperatures, than homopolymer at the expense of quite small reductions in other properties. Copolymer sheets are used extensively in Hygienic Lining Systems for wall and ceiling cladding. Hygienic, tough and impact resistant, it will stand repeated steam cleaning and is ideal in all food industry applications.
