1. Product Overview
PPR (Polypropylene Random Copolymer) Sheets are extruded thermoplastic boards with a balanced combination of stiffness, toughness and hot-water performance. The random copolymer structure improves impact strength and stress-crack resistance compared with homopolymer PP, especially under typical service temperatures and pressures in water and process systems. This makes PPR sheets suitable for both industrial installations and building applications where long-term reliability and low maintenance are critical.
- Uniform thickness and flatness: Supports accurate machining, reliable sealing and easy installation on frames or supports.
- Smooth, clean surface: Easy to wash down, with low tendency to scale or accumulate dirt.
- Low water absorption: Maintains mechanical properties and dimensions even in humid or submerged conditions.
2. Key Features
Mechanical & Physical Properties
- Low density: Lightweight material that reduces structural load and simplifies lifting, transport and installation on site.
- Good impact resistance: Withstands daily knocks and vibration, suitable for panels, guards and structural components.
- Dimensional stability: Maintains shape under typical operating temperatures and loads when correctly supported.
Chemical & Temperature Resistance
- Corrosion resistance: Suitable for many inorganic acids, alkalis and salts commonly found in process, water-treatment and cleaning media.
- Hot & cold water capability: Designed to work within the normal PPR temperature range for hot and cold water service, HVAC and process piping systems.
- No rust or scaling: Will not rust, pit or form scale as many metallic materials do, helping to keep systems clean and low-maintenance.
Processing, Hygiene & Safety
- Excellent weldability: Can be joined by hot-air welding, butt welding and other thermoplastic welding methods to build tanks, ducts and complex fabricated equipment.
- Easy to machine: Can be cut, drilled, routed and CNC machined with standard plastic processing tools.
- Clean and low-odor: Smooth, non-toxic surface suitable for many environments requiring cleanliness or easy disinfection.
3. Typical Applications
Industrial Applications
- Chemical & wastewater treatment: Liners and panels for tanks, channels, launders and tanks exposed to corrosive liquids.
- Process equipment: Structural and protective panels for scrubbers, filters, dosing systems and other environmental or chemical equipment.
- Industrial protection: Machine guards, splash shields, lightweight covers and barrier panels.
Construction & Building Services
- Water & HVAC systems: Panels, covers and support boards associated with PPR piping in buildings and technical rooms.
- Interior technical areas: Wall panels, equipment backboards and protective cladding in plant rooms, pump rooms and utility spaces.
- Infrastructure projects: Sheets used around water, HVAC or service installations where corrosion resistance and low weight are important.
