Polymat PP
Polypropylene (PP) is a widely used thermoplastic polymer known for its versatility, low density, and cost-effectiveness. It offers a balanced set of properties that make it suitable for a wide range of applications across various industries.
Mechanical Properties
- Tensile Strength: Typically around 30 to 50 MPa, providing good performance under stress for many applications.
- Impact Resistance:Offers good impact resistance, though it may become brittle at low temperatures.
- Fatigue Resistance: Performs well over repeated stress cycles, making it suitable for applications with cyclic loading.
- Low Coefficient of Friction: Exhibits a low coefficient of friction, which reduces wear in moving parts and enhances longevity.
- Modulus of Elasticity: Around 1.5 to 2.0 GPa, providing adequate rigidity and stability under load.
- Creep Resistance: Shows moderate resistance to deformation under constant load, with acceptable long-term dimensional stability.
Thermal Properties
- Continuous Service Temperature: Suitable for use up to approximately 100°C (212°F), beyond which thermal performance may degrade.
- Thermal Stability: Remains stable in moderate thermal environments, though high temperatures may affect its properties.
- Thermal Expansion: Exhibits moderate thermal expansion, which should be accounted for in precision applications.
- Glass Transition Temperature: Around -10°C (14°F), below which PP can become brittle.
- Thermal Insulation Properties: Provides effective insulation against heat, which helps in managing thermal conditions in various applications.
- Thermal Oxidative Stability: Generally stable in moderate temperature oxidative environments; however, long-term exposure to high temperatures may lead to degradation.
Chemical Properties
- Chemical Resistance: Highly resistant to many acids, bases, and organic solvents, making it suitable for a wide range of chemical environments.
- Resilience to Corrosive Environments: Performs well in environments with moderate corrosive chemicals, though prolonged exposure to strong acids or bases may cause degradation.
- Resistance to Hydrolysis: Shows moderate resistance to moisture and steam, but extended exposure can affect its mechanical properties.
- Non-reactivity: Generally stable with most chemicals, ensuring consistent performance in various applications.
- Durability in High-Temperature Chemical Environments: Effective in many chemical environments, but high temperatures and aggressive chemicals can impact performance.
- Moderate Permeability: Has moderate permeability to gases and liquids, which should be considered for containment applications.
