Polymer Linear Thermal Expansion Coefficient Tester for Rubber and Plastics
Published: 5/28/2020
Bench-top system for measuring linear thermal expansion of rubber and plastic polymers within a controlled temperature range in accordance with GB 1036-2008 and ASTM D696. Suitable for R&D and quality control to determine thermal expansion behavior, softening point, glass transition, and phase changes.
Product Description
The PCY-SL-30 measures the change in length of polymer specimens under a defined temperature differential to calculate average linear thermal expansion coefficients. It is designed for laboratory and industrial environments to support materials evaluation, process development, and quality assurance.
The system uses a thermostatic bath for precise low-temperature control and a quartz-based measurement fixture to ensure stability and accuracy. Data acquisition can be interfaced to an upper computer for online testing and records management, enabling efficient workflows and traceable results.
