Natural Polypropylene PPH Rod 140mm for Manufacturing Applications

140mm Dia Natural Polypropylene Round Rod

Natural Polypropylene Homopolymer (PPH) Rod 140mm is a versatile thermoplastic material designed for industrial fabrication where chemical resistance, dimensional stability and lightweight construction are essential. With a specific gravity of 0.91, it offers an excellent strength-to-weight balance and is light enough to float on water.

Its resistance to aggressive chemicals and acids, particularly sulphuric acid, makes it suitable for manufacturing storage tanks, chemical handling systems and industrial accessories. The smooth, non-stick surface helps prevent materials from adhering, making it useful in equipment exposed to cement, concrete and other substances.

PPH maintains good stiffness at elevated temperatures and supports continuous operation between 0°C and +100°C, exceeding the working temperature capability of PPC. Its low water absorption, excellent weldability and food-compliant properties provide additional flexibility for manufacturing and engineering projects.

Key Features

• Strong resistance to acids, including sulphuric acid.
• Excellent chemical and corrosion resistance.
• Very low density of 0.91 for lightweight applications.
• Smooth surface with non-stick characteristics.
• Good impact strength and rigidity.
• Easily welded for customised fabrication.
• Food-compliant material with low moisture absorption.
• HB fire classification; continues burning when the flame is removed and may produce molten drips.

Applications

• Industrial acid storage vessels.
• Chemical processing installations.
• Water treatment systems.
• Medical and food-processing equipment.
• Cement and concrete handling machinery.
• Protective plugs, bungs and threaded components.
