Polymer and Elastomer Mechanical Testing
Overview of
Polymer and Elastomer Mechanics
Elastomers are soft, highly extensible materials with nonlinear elastic and viscoelastic responses. Their mechanical properties depend on polymer chemistry, crosslink density, curing conditions, temperature, and filler content. These materials are commonly used in engineered tissues, microfluidic devices, wearable electronics, and soft robotic structures.
- Mechanical characterization supports research in:
Understanding these properties ensures that elastomers perform as expected in dynamic environments.
Importance of Mechanical Evaluation for Elastomers and Soft Polymers
Researchers use mechanical testing to:
- Quantify tensile strength, elongation and modulus in PDMS, silicone and TPU
- Evaluate compressive deformation and bulk stability
- Measure bending stiffness of thin polymer strips
- Assess shear and interfacial mechanics in composite systems
- Characterize viscoelastic recovery and rate dependence
- Determine fatigue resistance and long-term durability
- Evaluate mechanical performance across curing conditions and formulations
These data guide materials selection and validate polymer suitability for biomedical or engineering applications.
