Polypropylene offers a good balance of thermal, chemical and electrical properties with moderate strength. It possesses a good strength to weight ratio and due to its hard, high gloss surface, polypropylene is ideally suited to environments where there is concern for bacteria build up that can interfere with flow. Polypropylene sheets can be heat formed, shaped and welded, it also displays excellent corrosion resistance to a wide range of items and is easily welded with a plastic welder. Polypropylene is not UV stabilized but is USDA approved and meets FDA standards. It is rigid with fair impact resistance and very good abrasion resistance.
