Polypropylene (PP) is a thermoplastic resin material characterized by high rigidity, chemical resistance, and lightweight properties.

Mechanical and Thermal Properties

  1. Heat Resistance: Melting point is approximately 170°C. It can maintain its shape at high temperatures up to 150°C without noticeable deformation.
  2. Chemical Resistance: Excellent resistance to acids, alkalis, and organic solvents. Low water absorption, making it suitable for use in humid environments.
  3. Lightweight: With a density of only 0.90~0.91, it is one of the lightest materials among general-purpose resins.

Thermal Properties and Dimensional Stability

  1. Vicat Softening Temperature: About 150°C. It can withstand temperatures up to 170°C without external force.
  2. Thermal Deformation Resistance: Maintains excellent shape stability in high-temperature environments, making it suitable for applications requiring high-temperature resistance.
  3. Thermal Expansion Coefficient: Relatively low, with a shrinkage rate between 1.0-2.5%, providing good dimensional stability.

Chemical and Thermal Stability

  1. Crystalline Structure: Provides the material with high mechanical strength, allowing it to maintain stable performance in corrosive environments.
  2. Chemical Corrosion Resistance: Can resist most acids, alkalis, and organic solvents.
  3. Low Water Absorption: The material absorbs little to no water, making it suitable for humid environments and applications requiring long-term stability.

Reinforced Materials

  1. Addition of Reinforcing Agents: By adding reinforcing agents such as glass fibers, the strength and thermal deformation resistance of polypropylene are significantly enhanced.
  2. Suitable Applications: Reinforced materials perform excellently under high-temperature and high-load conditions, suitable for applications requiring high mechanical strength and durability.
  3. Dimensional Accuracy: The reduced thermal expansion and shrinkage in reinforced materials improve product dimensional accuracy and long-term service life.

Applications

  1. Widely Used: Extensively used in automotive, packaging, construction, household appliances, and other fields, particularly in applications requiring heat resistance, chemical corrosion resistance, and lightweight properties.
  2. Automotive Parts: Due to its high strength, low density, and chemical stability, it is suitable for manufacturing automotive parts.
  3. Industrial Fans: Reinforced polypropylene composites are commonly used to manufacture industrial fan blades, pump casings, and other critical components.
