ASTM C177: Thermal Conductivity
How a material responds to heat decides whether it survives its application. MatX Lab measures transitions, stability, expansion, and composition across temperature, by DSC, TGA, DMA, and TMA.
It is known that how a material responds to heat decides whether it survives its application. Thermal analysis measures the transitions, stability, expansion, and composition that change with temperature, the properties a datasheet number cannot capture. MatX Lab uses thermal methods to confirm a polymer was formulated and cured correctly, measure filler content, find a transition that drives failure, or characterize how a material behaves across its service range. The work tells you what a material does as the temperature moves.
Thermal analysis is a mix of methods that measure a material's properties as a function of temperature. Different methods track different properties; some track heat flow to find transitions like the glass transition and melting, some track mass loss to measure composition and stability, and others track dimensional or mechanical change to measure expansion and stiffness. Together they reveal how a material was made and how it will behave when heated or cooled.
Thermal work usually pairs a transition method with a compositional or mechanical one, and we scope the combination your question needs. Each technique below links to its own page.
It measures glass transition, melting, crystallization, and cure by tracking heat flow. It confirms formulation and processing of polymers, composites, and other materials.
Here, mass loss is measured with temperature to determine filler content, volatiles, moisture, and thermal stability. It is a workhorse for compositional and degradation questions.
This measures modulus and damping versus temperature and frequency, giving glass transition and viscoelastic behavior under load, which a static test misses.
Measures dimensional change with temperature, including softening and the coefficient of thermal expansion, important for parts that must fit and seal.
Measures linear thermal expansion of solids with high precision across a wide temperature range, common for ceramics, glass, and metals.
Measure the deflection temperature under load and the softening point of plastics, both used in material selection and qualification.
It measures how a material conducts and diffuses heat, essential for insulation, electronics, and thermal-management materials.
Thermal analysis is the right method whenever temperature behavior, cure, or composition is the question.
Thermal analysis applies wherever polymers, composites, and temperature-sensitive materials are used.

Yes. DSC measures glass transition, melting, crystallization, and cure by tracking heat flow, and DMA provides glass transition under mechanical load. We report the transitions against your specification and note the method and conditions used.
Yes. Thermogravimetric analysis measures filler, additive, moisture, and volatile content by mass loss with temperature, and it also characterizes thermal stability. It is one of the most common thermal analyses, often run alongside DSC.
Yes. TMA and push-rod dilatometry measure the coefficient of thermal expansion across a wide temperature range for polymers, composites, ceramics, and metals. We report expansion behavior against your requirements.
MatX Lab redirects each thermal method to the accredited partner laboratory whis is best suited to do it, so that DSC, TGA, and mechanical thermal work run as one program. One contact, one report. Methods are aligned to ASTM, ISO, IEC, UL, and MIL-STD where a published method applies. MatX Lab is an analysis provider, not a standards body, and issues no certifications. Every engagement can sit under an NDA.
