Low-Temperature Compression Set Testing Machine

Low-Temperature Compression Set Testing Machine
A specialized testing instrument designed to evaluate the compression set of rubber, elastomers, and flexible polymers at low temperatures—measuring their ability to recover shape after being compressed for extended periods in cold environments. Compression set, expressed as a percentage of permanent deformation, indicates how well materials retain elasticity and sealing performance in cold-climate applications.

 

Equipped with a temperature-controlled chamber (capable of reaching -70°C or lower), precision compression fixtures, and calibrated spacers, the machine follows a standardized process:

 

  1. Compressing the sample to a fixed percentage of its original thickness (e.g., 25%, 50%) using a fixture.
  2. Maintaining the compressed sample at a target low temperature (e.g., -40°C) for a specified duration (typically 22–168 hours).
  3. Removing the compression, allowing the sample to recover at room temperature, and measuring the residual deformation to calculate compression set.

 

Key applications include testing materials for:

 

  • Automotive & Aerospace: Seals, gaskets, and O-rings in engines, braking systems, or aircraft exposed to cold climates or refrigerated zones.
  • Industrial & Refrigeration: Elastomers in cold-chain equipment, freezer door seals, and cryogenic hoses requiring long-term sealing integrity.
  • Consumer Goods: Rubber components in winter footwear, outdoor gear, and appliances used in low-temperature environments.

 

Compliant with international standards such as ASTM D395, ISO 815, and DIN 53517, this tester is trusted by rubber manufacturers, quality control labs, and automotive suppliers. It provides critical data to optimize material formulations, validate sealing performance, and ensure that components maintain functionality—preventing leaks, pressure loss, or equipment failure in cold conditions.
