Natural Polypropylene Round Rod 45mm Dia for Chemical Engineering

Polypropylene Round Plastic Rod (Natural) 50mm Dia

Natural Polypropylene Homopolymer Rod 50mm is a substantial plastic engineering material suitable for manufacturing structural fittings and custom-made industrial parts. Its combination of stiffness, low weight and resistance to aggressive chemicals makes it useful in environments where metal components may be affected by corrosion.

PPH has a specific gravity of around 0.91 and supports operating temperatures from 0°C to +100°C. Compared with polypropylene copolymer, it offers greater temperature capability while maintaining low moisture uptake. Its excellent weldability also allows fabricators to produce joined structures, tank assemblies and specialist equipment.

The material performs well when exposed to acids, including sulphuric acid, and its smooth surface helps reduce the adhesion of substances such as cement and concrete. It can also withstand repeated impacts, making it suitable for protective accessories and industrial fittings. The natural grade is food compliant for appropriate applications.

This polypropylene rod carries an HB fire classification, meaning it is combustible and may continue burning once the ignition source is removed.
