Differential scanning calorimetry is used to assist in identifying specific polymers, polymer alloys, and d3481 polymer additives, which exhibit thermal transitions. One of the pans is filled with sample and the other is kept empty as a control. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.
Weak glass transitions such as in polyethylene and polypropylene are usually not strong enough to detect. Our polymer testing experts have years of experience across a variety of industries, and can help you overcome the unique challenges inherent with non-metallic materials.
This may indicate a chemical reaction such as curing is taking place. Inspection Validating the specifications, value and safety of your raw materials, products and assets.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. The pan filled with sample will require extra energy to heat through a transition such as a melting point because extra energy is required to change the molecule from a solid to a molten state. The ISO procedures provide additional information not supplied by this test method. You may delete a document from your Alert Profile at any time.
