Product catalog summary
Overview of TMA/DTMA Method: Thermo Mechanical Analysis (TMA) is a technique used to measure sample displacement as a function of temperature, time, and applied force. It is commonly used to characterize linear expansion, glass transitions, and softening points of materials. The method involves applying a constant force to a specimen while varying the temperature.
Typical Applications: TMA is used for tension studies, determining softening behavior, glass transition temperatures, phase changes, mechanical behavior under force, expansion coefficients, sintering behavior, volumetric expansion, E modulus, and friction resistance.
Key Features: The TMA Platinum Series offers high resolution for measuring nanometer changes, dynamic load TMA for weak transitions, a wide measuring range from -150°C to 1600°C, and a modular design for future expansion. It includes a gas-tight cell for controlled environments and supports hyphenated techniques like evolved gas analysis.
Sample Chamber and Furnace: The sample chamber is centrally located in the furnace, allowing controlled temperature and atmosphere. An optional mass flow controller is available for gas regulation. The robust furnace design ensures rapid heating and cooling with excellent control.
Sensor and Dynamic TMA Mode: Dimensional changes are transmitted via a pushrod to a precise inductive transducer, ensuring reproducibility. The dynamic TMA mode studies visco-elastic behavior by alternating the force on the probe.
Sample Holders and Pressure Control: A variety of sample holders are available, and automatic pressure control adjusts contact pressure between 10mN and 20N.
Cooling System: The liquid nitrogen cooling system is automated, eliminating manual refilling and improving reproducibility.
Software Features: The software, compatible with Microsoft Windows, includes modules for temperature control, data acquisition, and evaluation. Features include text editing, data security, thermocouple protection, curve comparison, data export, multi-method analysis, and statistical evaluation.
Applications and Case Studies: The document provides examples of TMA applications, including the evaluation of elastomers, polyvinylchloride, silicon rubber, and polycarbonate. Each material's glass point and behavior under temperature changes are discussed.
Additional Features: Optional features include DTA evaluation and rate-controlled sintering software. The document also highlights the importance of the DTA feature for evaluating thermal expansion and phase transitions.

Linseis Thermomechanical Analysis - TMA-2

Thermo mechanical analysis (TMA) easily and rapidly measures sample displacement (growth, shrinkage, movement, etc.) as a function of temperature, time, and applied force. Traditionally, TMA is used to characterize linear expansion, glass transitions, and softening points of materials by applying a constant force to a specimen while varying temperature. For expansion measurements, a probe rests on a sample on a stage with minimal downward pressure. Other constant force experiments include measurement of penetration, bending, tension, shrinkage, swelling, and creep (sample motion measured as a...

1. Elastomers Because of their very special and versatile properties, polyurethanes Elastomers have found wide application in virtually every industry, varying from the automotive, electrical and electronic industry, design and textile industry, to the mining and heavy duty industry. Evaluation of Elastomers specifically developed for applications above 0°C. The glass point was detected at 29.9°C. When further increasing the temperature, additional expansion of the material in the elastic range occurs. The plastic range of the material has not been reached during this evaluation. 2. Polyvinylchloride...

Delta-L(2)[BK-00-4] DTA Signal [BK-00-3] Base Line [BK-00-3] 4. DTA - Feature The thermal expansion of rock crystal ( -SiO2) can be easily evaluated with the L75 Dilatometer. The additional DTA feature enables an in depth view of the thermal behavior of the material. The DTA measurement is a mathematical routine based on the sample temperature. Exo- and endothermic effects influence the change of the sample temperature during the dynamic heating or cooling cycle. At app. 575°C the phase transition from - to -SiO2 takes place. The deviation of the measured temperature from the literature value...
