GF reinforced-General grades
Polypropylene (PP) is a thermoplastic resin material characterized by high rigidity, chemical resistance, and lightweight properties.
Mechanical and Thermal Properties
- Heat Resistance: Melting point is approximately 170°C. It can maintain its shape at high temperatures up to 150°C without noticeable deformation.
- Chemical Resistance: Excellent resistance to acids, alkalis, and organic solvents. Low water absorption, making it suitable for use in humid environments.
- 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
- Vicat Softening Temperature: About 150°C. It can withstand temperatures up to 170°C without external force.
- Thermal Deformation Resistance: Maintains excellent shape stability in high-temperature environments, making it suitable for applications requiring high-temperature resistance.
- Thermal Expansion Coefficient: Relatively low, with a shrinkage rate between 1.0-2.5%, providing good dimensional stability.
Chemical and Thermal Stability
- Crystalline Structure: Provides the material with high mechanical strength, allowing it to maintain stable performance in corrosive environments.
- Chemical Corrosion Resistance: Can resist most acids, alkalis, and organic solvents.
- Low Water Absorption: The material absorbs little to no water, making it suitable for humid environments and applications requiring long-term stability.
Reinforced Materials
- Addition of Reinforcing Agents: By adding reinforcing agents such as glass fibers, the strength and thermal deformation resistance of polypropylene are significantly enhanced.
- Suitable Applications: Reinforced materials perform excellently under high-temperature and high-load conditions, suitable for applications requiring high mechanical strength and durability.
- Dimensional Accuracy: The reduced thermal expansion and shrinkage in reinforced materials improve product dimensional accuracy and long-term service life.
Applications
- 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.
- Automotive Parts: Due to its high strength, low density, and chemical stability, it is suitable for manufacturing automotive parts.
- Industrial Fans: Reinforced polypropylene composites are commonly used to manufacture industrial fan blades, pump casings, and other critical components.
