DSC Testing

Differential Scanning Calorimetry

Unlock the thermal secrets of your polymers with precision DSC analysis. Measure melting points, glass transitions, crystallization behavior, and thermal stability with expert interpretation.

What is DSC?

Differential Scanning Calorimetry (DSC) is a thermal analysis technique that measures the heat flow into or out of a material as a function of temperature or time. This powerful method reveals critical thermal transitions and properties that define how your polymer will perform in real-world applications.

DSC works by heating (or cooling) a small sample of your material alongside an inert reference, measuring the difference in heat flow required to maintain both at the same temperature. When your polymer undergoes a thermal transition—such as melting, crystallization, or glass transition—the instrument detects the energy change and records it as a peak or shift in the thermogram.

🔥 Melting Point (Tm)

Identify the temperature at which crystalline regions melt, critical for processing and application temperature limits.

❄️ Glass Transition (Tg)

Determine when amorphous regions transition from glassy to rubbery state, affecting mechanical properties.

💎 Crystallization

Measure crystallization temperature and kinetics, essential for processing optimization and product quality.

⚡ Heat Capacity

Quantify specific heat capacity and enthalpy changes for thermal management applications.

  • Reaction kinetics

Common Applications

Quality Control & Incoming Material Verification

Verify that incoming polymer resins meet specifications. Detect batch-to-batch variations, identify contamination, and ensure consistency in your supply chain. DSC provides a thermal fingerprint that can quickly flag off-spec materials before they enter production.

Product Development & Formulation

Optimize polymer blends, composites, and formulations by understanding how different components interact thermally. Measure miscibility, phase separation, and the impact of additives on thermal properties. Perfect your formulation to achieve target performance characteristics.

Processing Optimization

Set optimal processing temperatures for injection molding, extrusion, and thermoforming. Understand crystallization kinetics to control cooling rates and cycle times. Avoid thermal degradation by identifying safe processing windows.

Failure Analysis & Troubleshooting

When parts fail or products underperform, DSC reveals what went wrong. Identify excessive crystallinity, incomplete cure, thermal degradation, or contamination. Compare failed samples to good samples to pinpoint the root cause.

Competitive Analysis

Reverse-engineer competitor materials by analyzing their thermal signatures. Identify the polymer type, estimate crystallinity, and detect the presence of additives or fillers. Gain insights to inform your own product development.
