1. Product Overview
PP sheets are extruded polypropylene boards with a smooth or lightly textured surface and uniform thickness. Polypropylene combines low density with good stiffness and chemical resistance, making PP sheets a cost-effective alternative to metal or PVC in many industrial and environmental applications.
- Material type: Polypropylene (PP), typically homopolymer for higher stiffness or specified grades on request.
- Appearance: Flat boards with good flatness and consistent thickness for reliable fabrication and assembly.
- Processing: Suitable for cutting, welding and machining into finished parts or complete units.
2. Key Features
Mechanical & Physical Properties
- Low density: Much lighter than steel or other metals, reducing structural load and easing on-site handling.
- Good stiffness: Maintains shape and dimensional stability when correctly supported in panels and structural components.
- Impact resistance: Adequate toughness for most industrial uses, such as guards, covers and housing panels.
Chemical & Thermal Properties
- Chemical resistance: Suitable for many inorganic acids, alkalis and salts, commonly used in chemical, plating and wastewater equipment.
- Corrosion-free: Will not rust or corrode like metal; no metal ion contamination of media.
- Temperature performance: Designed to operate within the typical PP temperature range in industrial environments.
Processing, Hygiene & Safety
- Excellent weldability: Hot-air and butt welding allow assembly of tanks, ducts, scrubbers and structural components.
- Easy machining: Can be cut, drilled, routed and CNC machined with standard plastic-fabrication equipment.
- Clean surface: Smooth, low-odor surface that is easy to clean and maintain; suitable for many general industrial and semi-hygienic applications.
3. Typical Applications
- Chemical industry: Tanks, plating lines, scrubbers, fume hoods, splash guards and corrosion-resistant linings.
- Environmental & wastewater treatment: Panels and linings for treatment tanks, launders, channels and covers.
- Ventilation & exhaust systems: Exhaust ducts, vents and housings used in corrosive or humid environments.
- Mechanical & industrial equipment: Machine guards, covers, protective plates and lightweight structural parts.
- General fabrication: Custom components, panels and housings produced by welding and machining PP sheets according to drawings.
