PP, PE, and ABS sheets are widely used thermoplastic materials across industries such as chemical processing, electronics, machinery, packaging, and environmental protection. Here's a detailed breakdown:


1. PP Sheets (Polypropylene Sheets)

1.1 Pure PP Sheets

  • Features: Low density, high chemical resistance, heat resistance, hygienic
  • Available Options: Can be filled, flame-retardant treated, embossed, or matte finished
  • Aplicações: Chemical anti-corrosion equipment, water treatment systems, food processing machinery, environmental protection projects

1.2 Modified PP Sheets (Calcium-Filled)

  • Advantages: Improved estabilidade dimensional, rigidity, e heat resistance; lower cost
  • Ideal For: Budget-conscious structural applications requiring moderate performance

1.3 Reinforced PP Sheets (Glass-Fiber Reinforced)

  • Reinforcement: 20% glass fiber
  • Performance Gains: Twice the strength and rigidity compared to pure PP; excellent thermal resistance, low-temperature impact resistance, corrosion resistance, e arc resistance; low shrinkage
  • Recommended Use: High-strength, high-durability components in corrosive or thermally demanding environments

Specifications:

  • Thickness: 2–12mm (Max width: 1500mm)
  • Thickness: 12–30mm (Max width: 1300mm)
  • Thickness: 30–50mm (Max width: 1000mm)
  • Length: Customizable

2. PE Sheets (Polyethylene Sheets) – HDPE & LDPE

2.1 Material Types

  • PEAD (High-Density Polyethylene): High rigidity, strength, and melting point; suitable for blow molding, injection molding
  • LDPE (Low-Density Polyethylene): Soft, flexible, low strength and melting point; ideal for films, cable insulation

2.2 Key Features

  • High toughness, tensile strength, and wear resistance
  • Chemical resistance to acids and alkalis
  • Can be modified, flame-retardant treated, embossed, or matte finished

2.3 Applications

  • Chemical containers, food processing surfaces, protective packaging, textile aids, anti-corrosion liners, mechanical buffers

Specifications:

  • Thickness: 1–40mm
  • Max Width: 1300mm
  • Length: Customizable

3. ABS Sheets (Acrylonitrile-Butadiene-Styrene)

Features

  • Smooth surface, attractive colors, and excellent comprehensive mechanical properties
  • Highly processable: easy to cut, bond, thermoform, and print
  • Can be flame-retardant, reinforced, embossed, or matte finished

Aplicações

  • Appliance housings, electronics enclosures, automotive interior parts, toy components, industrial packaging

Specifications:

  • Thickness: 1–10mm
  • Width & Length: Customizable
