Durability testing is essential for ensuring rubber products will perform reliably throughout their expected service life. Various test methods evaluate different aspects of durability and performance.
Aging Tests
Aging tests simulate long-term exposure to environmental conditions:
- Heat Aging: Exposure to elevated temperatures to assess thermal stability
- Ozone Resistance: Testing resistance to ozone degradation
- UV Exposure: Evaluating resistance to ultraviolet radiation
- Weathering: Combined exposure to multiple environmental factors
Mechanical Tests
Mechanical tests evaluate physical durability:
- Tensile Testing: Measures strength and elongation properties
- Compression Set: Evaluates permanent deformation after compression
- Fatigue Testing: Assesses resistance to repeated stress cycles
- Abrasion Resistance: Measures wear resistance
Chemical Resistance Tests
Chemical compatibility testing:
- Immersion in various fluids
- Volume change measurement
- Hardness change evaluation
- Property retention after exposure
Performance Tests
Application-specific performance testing:
- Seal performance under pressure
- Leak testing
- Vibration resistance
- Temperature cycling
Accelerated Testing
Accelerated tests predict long-term performance:
- Elevated temperature exposure
- Increased stress levels
- Accelerated aging protocols
- Life prediction modeling
Comprehensive durability testing ensures that rubber products will meet performance requirements throughout their intended service life, providing confidence in their reliability.
