Overview of HDPE100 Grade Boards

1. Key Characteristics

Physical Properties

HDPE100 grade boards are high-crystallinity, non-polar thermoplastic resins. They appear milky white in their natural state, with a degree of translucency in thin sections. These boards have a waxy texture, low density, and excellent low-temperature resistance, maintaining performance at temperatures as low as -70°C to -100°C. They exhibit superior impact resistance even at -40°C, along with good toughness and tensile strength, making them suitable for cold environments.

• Specifications: Thickness ranges from 3–40 mm, width from 1000–2400 mm, and length can be customized to any size.

Chemical Properties

HDPE100 boards offer excellent chemical stability, resisting most acids, alkalis, organic solvents, and hot water. However, they are not resistant to oxidizing acids (e.g., concentrated nitric acid) or certain chemicals like aromatic hydrocarbons (e.g., xylene) and halogenated hydrocarbons (e.g., carbon tetrachloride), which may cause chemical corrosion.

• Moisture Resistance: Non-hygroscopic with excellent water vapor barrier properties, ideal for packaging applications.
• Chemical Resistance: Withstands most household and industrial chemicals, ensuring durability in harsh environments.

Electrical Properties

HDPE100 boards have outstanding electrical properties, particularly high dielectric strength, making them suitable for electrical insulation applications such as wires and cables. They also feature low water absorption and minimal water vapor permeability, enhancing their reliability in electrical systems.

2. Applications

Medical and Consumer Goods

HDPE100 boards are used in medical device components, seals, and other consumer products due to their safety and durability.

Industrial Applications

• Mechanical Engineering: Widely used as cutting boards, sliding profiles, and linings for silos, hoppers, chutes, pipelines, and slag trenches. Their anti-wear, anti-clogging, and anti-corrosion properties make them ideal for wear-resistant mechanical components, such as coal bunker liners, chute liners, conveyor belt slide plates, and coal baffle plates.
• Chemical Industry: Their resistance to most acids, alkalis, organic solvents, and hot water (except oxidizing acids) makes HDPE100 boards suitable for corrosion-resistant structural materials in chemical storage and transportation equipment.
• Power Industry: Leverages their excellent insulation properties for components in electrical equipment, ensuring operational safety and reliability.
• Other Industrial Sectors: HDPE100 boards are used in gas transmission, water supply, sewage systems, agricultural irrigation, fine particle solid transport in mining, and applications in oilfields and telecommunications. Related HDPE materials (e.g., HDPE100 grade pipes) demonstrate similar advantages, including:
  • Long service life (up to 50 years under normal conditions from -20°C to 65°C).
  • High hygiene (no metal additives, no scaling, no bacterial growth).
  • Resistance to various chemical media.
  • Smooth inner walls for excellent wear resistance and high impact strength.
  • Lightweight for easy transportation and installation.

These properties highlight the potential of HDPE100 boards in similar applications.
