Thermal Expansion Testing Service

Thermal Expansion Testing Service

Thermal expansion testing is a critical analytical technique used to determine the response of materials to changes in temperature. This method assesses how materials expand or contract with fluctuations in temperature, which is quantified by the Coefficient of Thermal Expansion (CTE). Understanding thermal expansion is essential for the development and application of materials in industries where temperature variations are common, ensuring the longevity and reliability of products.

Principles of Thermal Expansion Testing

From a scientific perspective, thermal expansion testing is grounded in the observation that materials change volume or dimension in response to temperature changes. This phenomenon is attributed to the increased kinetic energy of molecules as temperature rises, leading to greater intermolecular distances. The CTE, defined as the fractional change in length per degree of temperature change, is a material-specific constant that is crucial for predicting material performance under varying thermal conditions.

Advantages of Thermal Expansion Testing

Predictive Analysis

It allows for the anticipation of material behavior in different thermal environments, aiding in the design of more reliable and durable products.

Material Selection

It facilitates the selection of appropriate materials for specific applications, particularly in industries such as aerospace, automotive, and construction where temperature extremes are common.

Quality Control

It serves as a quality control measure to ensure consistency in material properties, which is vital for safety-critical applications.

Our Services

At CD BioSciences, we specialize in providing comprehensive thermal expansion testing services tailored to the needs of environment-friendly materials analysis. Our services are designed to support the development of sustainable materials that can withstand the rigors of temperature changes while maintaining their integrity and performance.

Methods of Thermal Expansion Testing

We employ a variety of methods to conduct thermal expansion testing, each chosen based on the specific requirements of the material under test:

  • Dilatometry: This method uses a dilatometer to measure the linear dimensional changes of a material as a function of temperature.
  • ThermoMechanical Analysis (TMA): A TMA measures the dimensional response of a material to a controlled temperature program and can provide data on transitions such as glass transition and melting points.
  • Interferometry: Utilized for higher temperature measurements, interferometry provides precise displacement data.

Sample Requirements

To ensure accurate and reliable results, we have specific requirements for the samples submitted for testing:

  • Sample Dimensions: We require samples to be within specific size constraints to fit our testing equipment, typically with a diameter no greater than 0.5 inches (12.5 mm) for solid samples.
  • Sample Types: We can test a wide range of sample types, including solids, pastes, liquids, and phase change materials, using specialized holders designed for each type.
