Description

LR-TMA105 TMA Analyzer

Overview:

LR-TMA105 thermomechanical analyzer is a thermomechanical analysis method (TMA) used to study the mechanical properties of polymer materials. It can determine the temperature and deformation curve of materials under the condition of constant temperature rise, so as to determine the thermal expansion coefficient, glass transition temperature Tg, flow temperature Tf and other characteristics of materials. It can be widely used in the research and production of polymer and its synthetic materials, drugs, ceramics and other materials.
