1. Overview of Polypropylene (PP) Sheets
Polypropylene (PP) is a versatile thermoplastic known for its balance of strength, rigidity, and chemical resistance. PP sheets offer a lightweight yet durable solution for various industrial applications.
They are non-toxic, easily weldable, and possess excellent electrical insulation. However, they may become brittle in low-temperature environments.
2. Key Properties of PP Sheets
- Low density and lightweight
- Working temperature range: 5°C to 100°C
- High stiffness and tensile strength
- Good chemical resistance to acids, alkalis, and organic solvents
- Excellent electrical insulation
- Non-toxic and suitable for food contact
3. Advantages and Limitations of PP Sheets
Advantages:
- Cost-effective and readily available
- Good mechanical performance
- Weldable for custom fabrication
- Safe for medical and food-grade applications
Limitations:
- Moderate impact toughness
- Poor UV resistance without additives
- Brittle in cold environments
- Limited abrasion resistance
4. Applications of PP Sheets
- Valve and pump parts
- Sealing gaskets, spraying devices, and chemical tanks
- Fume hoods, dust-free rooms, semiconductor factory equipment
- Food processing equipment and cutting boards
- Electroplating and chemical handling systems
- Dental devices, toys, and household appliances
- General industrial and structural materials
5. Overview of UHMW-PE Sheets
Ultra-high molecular weight polyethylene (UHMW-PE) is a high-performance engineering plastic known for its superior wear resistance, impact strength, and chemical resistance.
UHMW-PE sheets are odorless, tasteless, non-toxic, and ideal for high-demand environments where abrasion and friction are concerns.
6. Key Properties of UHMW-PE Sheets
- Working temperature: -70°C to +100°C
- Abrasion resistance: 6–7x higher than PTFE, 2x more than HDPE, 9x that of stainless steel
- Low surface energy and non-stick characteristics
- Excellent resistance to acids, alkalis, salts, and moisture
- Low coefficient of friction for smoother flow
- Outstanding impact resistance and fatigue resistance
7. Applications of UHMW-PE Sheets
- Lining for silos, hoppers, and chutes
- Wear-resistant mechanical parts
- Power plants, mining and coal processing
- Steel plants, shipyards, and fertilizer factories
- Automotive components and engineering machinery
- Wastewater treatment plants and anti-corrosion systems
- Ports, docks, and heavy-duty equipment parts
