1. Key Characteristics of PPH Board
Mechanical & Physical Properties
PPH (polypropylene homopolymer) offers a good balance of stiffness and toughness. Compared with copolymer PP, homopolymer PPH has higher rigidity and better heat resistance, which is beneficial for structural panels and tanks that must maintain shape at elevated temperatures. The material is lightweight, with a density much lower than steel, reducing overall equipment weight and easing installation.
- Good stiffness: Maintains shape and dimensional stability under normal operating loads.
- Impact resistance: Sufficient toughness for most industrial applications; suitable for tank walls, ventilation panels and machine guards.
- Low density: Easier handling on site and lower structural load compared with metal materials.
Chemical & Thermal Properties
PPH boards are widely used in chemical and environmental equipment because of their strong resistance to many corrosive media. They perform well in many acid and alkali environments, making them suitable for long-term use in scrubbers, plating lines and wastewater treatment units.
- Chemical resistance: Excellent resistance to many inorganic acids, alkalis and salts; suitable for exhaust gas scrubbing, chemical tanks and etching lines.
- Temperature performance: Better heat resistance than many general plastics, suitable for warm liquids and process gases within the typical PP temperature range.
- Low water absorption: Maintains mechanical properties and dimensions in humid or wet service.
Processing & Hygiene
- Good weldability: Hot-air welding and butt welding can be used to assemble tanks, ducts, scrubbers and custom equipment.
- Easy fabrication: Boards can be cut, drilled, routed and machined into complex parts using standard plastic fabrication tools.
- Clean and smooth surface: Non-toxic, easy to clean, with low contamination and low odor, suitable for many industrial and semi-hygienic environments.
2. Typical Applications of PPH Board
- Chemical industry: Chemical storage tanks, reaction tanks, scrubbers, pickling lines, plating tanks, fume hoods and corrosion-resistant ducting.
- Environmental & wastewater treatment: Tanks, settling units, launders, covers and structural parts in wastewater and gas-treatment systems.
- Ventilation & exhaust systems: Corrosion-resistant air ducts, elbows, plenums and ventilation boxes used in chemical or coastal environments.
- Electronics & surface treatment: Tanks and equipment housings for PCB production, etching and cleaning lines.
- General industrial: Machine guards, splash shields, structural panels and lightweight protective covers.
