For liquid tanks, plating jigs, and food machinery. Selling cut-to-length lightweight PP round bars that are resistant to acids and alkalis.
PP (polypropylene) is a general-purpose resin that falls into the category of the lightest practical resins, with a specific gravity of 0.91. It is extremely resistant to acids and alkalis and hardly absorbs water, making it widely used in chemical tanks, plating lines, and parts for food machinery. It has a higher heat resistance than PE-HD, with a continuous use temperature of 100°C. KIRIURI.COM offers Takiron Polymer's PP Marbo 370 (natural and milky white) in round rod sizes (φ15 to φ180). We accommodate cutting to the required length and quantity. A material properties table and material explanation PDF are also available for download.

Applications/Examples of results
- Surface treatment and plating (chemical solution tanks, jigs, racks, partition plates) - Chemicals and water treatment (piping components, tank linings, nozzles) - Food machinery (line components, hoppers) - Conveying equipment (guides, impact materials) - Jigs (holding devices that come into contact with chemical solutions, holding devices that require weight reduction) [Selection] If heat resistance is required, PP (continuous 100°C) is suitable; if impact resistance at low temperatures is needed, PE-HD is appropriate. [Note] Below 0°C, it becomes weak against impact. It cannot be easily bonded as is, so mechanical fastening such as screws or fittings is recommended. It may swell or degrade in high-temperature oxidative acids and some organic solvents, so please verify under actual conditions.
