Creep Testing Explained: Validating Reliability in Plastics and Rubber

Creep Testing Explained: Validating Reliability in Plastics and Rubber


Predict service life. Reduce risk. Protect performance.

Designing durable plastic and rubber components is challenging. Unlike metals, polymers are viscoelastic, which means their performance changes over time under stress, temperature, and environmental exposure. Without the right data, unexpected failures, costly recalls, and compliance issues can arise.

Creep testing is an essential tool for understanding long-term performance. It gives manufacturers and engineers the insights to:
  • See how materials deform under sustained stress and heat.
  • Confidently predict durability and service life in real-world conditions.
  • Prevent premature failures in safety-critical and high-value applications.
