1. Product Overview
PPR (Polypropylene Random Copolymer) Sheets are extruded thermoplastic boards with balanced stiffness, toughness and hot-water performance. The random copolymer structure improves impact strength and stress-crack resistance compared with homopolymer PP, especially under medium temperatures and pressure in water systems. This makes PPR sheets suitable for both industrial installations and building applications where long-term reliability is important.
- Uniform thickness: Stable sheet thickness supports precise machining, reliable sealing and accurate installation.
- Smooth surface: Easy to clean and maintain, with low tendency to scale or accumulate dirt.
- Low water absorption: Maintains mechanical properties and dimensions in humid or submerged environments.
2. Key Features
Mechanical & Physical Properties
- Low density: Lightweight, reduces structural load and simplifies handling and installation on site.
- Good impact strength: Resists impact and vibration in daily operation, suitable for panels, covers and structural parts.
- Dimensional stability: Maintains shape under typical operating temperatures and pressures when correctly supported.
Chemical & Temperature Resistance
- Resistance to many chemicals: Suitable for contact with many inorganic acids, alkalis and salts commonly found in industrial processes and wastewater.
- Hot & cold water applications: Designed for service in hot and cold water systems within the normal PPR temperature range.
- Corrosion-free: No rusting, no metal ion release, and no scaling as in many metallic systems.
Processing, Hygiene & Safety
- Excellent weldability: Can be joined by hot-air or butt welding to assemble tanks, ducts, covers and fabricated equipment.
- Easy fabrication: Standard plastic-fabrication tools can be used for cutting, drilling, routing and CNC machining.
- Clean material: Smooth, non-toxic surface with low odor, suitable for many applications with hygiene or cleanliness requirements.
3. Typical Applications
Industrial Sector
- Chemical & wastewater treatment: Linings for tanks, channels, launders and equipment exposed to corrosive media.
- Process equipment: Panels, covers and internal components for scrubbers, filters and environmental protection systems.
- Industrial protection: Machine guards, splash shields and lightweight structural panels.
Construction & Water Systems
- Hot & cold water systems: Components, housings and panels associated with PPR piping systems in buildings.
- Building interiors: Wall panels, equipment backplates and protective cladding in technical rooms or utility areas.
- Infrastructure projects: Boards used around water, HVAC or service installations where corrosion resistance and low weight are important.
