PPH is the rigid backbone of the polypropylene family. By utilizing a 100% propylene monomer structure, this material achieves a high crystalline state, resulting in a product that is significantly stiffer than standard copolymers. This makes it the ideal candidate for load-bearing industrial structures where minimal deflection is required under thermal or mechanical stress.
In the world of aggressive chemistry, PPH stands as a formidable barrier. It is practically impervious to most acids, alkalis, and saline solutions. This inert nature makes it the standard for electrolytic plating baths, chemical storage vessels, and pickling tanks where metal alternatives would succumb to corrosion. It is an essential component for the chemical processing and wastewater treatment industries.
PPH outperforms its copolymer counterpart in heat-intensive applications. It can withstand short-term temperature spikes and maintains a continuous operating temperature around $100^\circ\text{C}$. This thermal resilience prevents warping and ensures the dimensional stability of fabricated components in hot-wash environments or industrial steam-cleaning processes.
This material is optimized for high-strength welding. It can be joined using hot-gas or extrusion welding techniques to create airtight, leak-proof seams for tanks and enclosures. While it does not support traditional adhesive bonding, its excellent machining properties allow for high-precision CNC routing and drilling to tolerances of $\pm 0.1 \text{ mm}$.
Ideal for heavy-duty industrial environments. Use PPH to fabricate chemical tanks, laboratory exhaust hoods, and ventilation systems. Its FDA compliance also allows for extensive use in pharmaceutical processing and industrial food production lines where hygiene and chemical washdowns are frequent.
