Polymer problems rarely announce themselves early. A batch may look normal at room temperature, process “almost fine,” and still fail later—brittle parts, discoloration, odor, surface defects, premature cracking, or unexpected weight loss during production. In most cases, the root cause is thermal behavior: moisture, volatiles, wrong filler content, grade substitution, or early degradation.
That’s why thermogravimetric analysis of polymers services in chennai – Kiyo R&D LAB are practical tools for polymer manufacturers, compounders, packaging converters, automotive suppliers, and R&D teams who need evidence, not guesswork.
Thermogravimetric Analysis (TGA) measures how a polymer changes in mass when heated under controlled conditions. It tells you when degradation starts, how many stages of decomposition occur, and what residue remains—information that mechanical tests cannot reveal.
Thermogravimetric Analysis (TGA) is a thermal analysis technique that measures the change in weight of a sample as a function of temperature (or time). The sample is heated at a controlled rate under a selected atmosphere such as nitrogen (inert) or air (oxidative).
In simple terms, TGA helps answer questions like:
With thermogravimetric analysis of polymers services in chennai – Kiyo R&D LAB, you get a clear thermogram (weight % vs temperature) that allows quick comparison of “good vs suspect” material.
Most polymer processing methods involve heat—extrusion, injection molding, blow molding, lamination, thermoforming, curing, or drying. If the polymer begins degrading near your processing temperature, you will see quality problems no matter how much you tweak machine settings.
TGA helps you validate whether a polymer grade is stable within your processing window. It also reveals hidden issues like excess volatiles, moisture contamination, or wrong filler percentage that can ruin consistency.
Using thermogravimetric analysis of polymers services in chennai – Kiyo R&D LAB supports better decisions on raw material selection, supplier approval, incoming QC, and product development.
The temperature where weight loss begins indicates when degradation starts. This helps define safe processing limits and compare thermal stability across batches.
Polymers often show multiple degradation stages—moisture release, additive loss, polymer backbone decomposition, and oxidation steps (depending on atmosphere). The shape and stages of the curve provide a thermal “fingerprint.”
Early weight loss at lower temperatures often indicates moisture or volatiles. In packaging films and molded parts, this can cause bubbles, voids, odor, and surface defects.
The remaining residue after heating provides a practical estimate of inorganic filler or ash content—critical for filled polymers and rubber compounds where filler ratio controls strength, stiffness, and cost.
Testing under different atmospheres (inert vs oxidative) helps evaluate oxidation behavior and long-term stability for applications exposed to heat and air.
TGA is used across many polymer quality and R&D tasks:
If your team is troubleshooting a recurring complaint, thermogravimetric analysis of polymers services in chennai – Kiyo R&D LAB can often shorten the diagnosis cycle.
Chennai’s manufacturing ecosystem demands faster technical decisions. Local access to testing helps keep production moving.
TGA results depend heavily on heating rate, sample preparation, sample mass, and atmosphere control. Small variations can change the curve and lead to wrong conclusions. Reliable thermal analysis requires controlled testing and clear reporting.
With thermogravimetric analysis of polymers services in chennai – Kiyo R&D LAB, you get:
Polymers can pass basic checks and still fail due to thermal instability. TGA helps you understand decomposition behavior, moisture/volatiles, filler content, and overall stability—data that directly improves processing and product reliability.
Choose thermogravimetric analysis of polymers services in chennai – Kiyo R&D LAB to make decisions based on measurable thermal evidence—so quality problems are prevented, not discovered after delivery.
