  2. AGENDA Thermal and Rheology, A window look TA Product line with Snap shot Present Market Share Our Competitors Areas that Needs Attention Service & Technical Points

  3. Thermal Analysis & Rheology • A complementary set of analytical techniques • Instruments and software for characterizing a wide range of materials • Measures changes in the Physical, and Chemical properties of materials as a function of time, temperature and other specific variables.

  4. What is Rheology ?Rheology is the science of flow and deformation of matter.The relationship between stress and deformation is a property of the material. We can therefore define Rheology as the study of stress-deformation relationships. What is a Rheometer? An instrument that measures both viscosity and viscoelasticity of fluids, semi-solids and solids It provides following information about the material’s: Viscosity (which is the function of shear rate or stress, time & temperature dependence) Viscoelastic properties (G’, G”, tan d) with respect to time, temperature, frequency & stress/strain Transient response (relaxation modulus, creep compliance, creep recovery)

  5. Types of Rheometers • Rotational (Shear) Rheometers • ARES (Strain Control – SMT) • AR (Stress Control – CMT) • Solids (Tensile/Bending) Rheometers • RSA (Strain Control – SMT) • DMA Q800 (Stress Control – CMT)

  6. Rheometers Product Line AR SERIES (CMT) ARES SERIES(SMT)

  7. AVAILABLE MODELS IN CMT RHEOMETERS AR-G2 (smart geom.) AR 2000EX AR 550 AR 1500EX

  8. AVAILABLE CONFIGURATION IN SMT RHEOMETERS ARES: Standard motor/2KFRT/Oven ARES LS-1: LS Motor/1KFRT/Peltier Bath. ARES LS-2: LS Motor/2KFRT/Oven ARES RDA: Standard Motor/2KSpring/Oven. ARES RFS: Standard Motor/1KFRT/Peltier Bath. ARES-HT: HT Motor/10KSpring/Oven.

  9. Applications Antiperspirant/Deodorant Shampoos Creams/Lotions Paints and coatings

  10. Thermal Analysis of Materials Thermal Analysis techniques are applicable to most material classes. Some of the more common classes include : • Polymers (Thermoplastics, thermosets, Elastomers, Polymer blends, copolymers). • Foodstuffs and Pharmaceuticals • Inorganic (Minerals & Clays) • Ceramics, metals and Alloys. • Petroleum derived products (fuels, greases, Lubricating oils, Bitumens and tars). • Materials are investigated (Loaded) in the liquid or solid state. • Over a wide temperature range -180°C/1600°C (depending on the technique).

  11. ACRONYMS DSC: Differential Scanning Calorimtery TGA: Thermo Gravimetric Analyzer SDT: Simultaneous Differential Thermal Analyzer DMA: Dynamic Mechanical Analyzer TMA: Thermo Mechanical Analyzer

  12. Thermal Analysis Techniques • Differential Scanning Calorimeter (DSC) -Modulated DSC (MDSC) • Thermo-Gravimetric Analysis (TGA) • Dynamic Mechanical Analysis (DMA) • Thermo-Mechanical Analysis (TMA)

  13. Thermal Analysis Measurements • Heat flow and heat capacity - DSC, MDSC • Weight change - TGA • Dimension changes - TMA • Modulus and damping - DMA

  14. Thermal Analysis of Materials Reveals • Low energy Transitions (b, g, Coefficients) – DMA • Glass transitions (Tg) - DSC, TMA, DMA • Softening - TMA, DSC, DMA • Melting - DSC, TMA, DMA • Re-ordering (Curing) – DSC, TMA, DMA • Thermal/Oxidative stability & weight change - TGA

  15. DSC (Differential Scanning Calorimetry) • A technique in which the heat flow rate (Power) to the sample is monitored against time or temperature while the temperature of the sample, in a specified atmosphere, is programmed. • ICTAC Definition (For Better Thermal Analysis. Ed John O. Hill) 1991

  16. DSC - What can it measure? • Glass Transitions • Melting Points • Crystallization Times and Temperatures • % Crystallinity • Heats of Fusion and Reactions • Specific Heat • Oxidative Stability • Rate of Cure • Reaction Kinetics • Purity • Thermal Stability

  17. Q Series™ DSCs Q 2000 Q 20 Q 200 Q 2000 is top-of-the-line, research grade with all options Q 200 is research grade and expandable Q 20 is a basic DSC

  18. Q2000 DSC:Auto samplerModulated DSCAdvanced Tzero capability (T4P Heat flow signal).User replaceable Cell Pressure DSC cell option Q200 DSC:Autosampler is optional Tzero heat flow correction option (T4) for improved transition resolution and baseline flatness.MDSC is an option with maximum heating rates of 5C/Minute available.Q20 DSC:Q20 It is an Entry level DSC which does not have the T Zero heat flow corrections for improved resolution and baseline flatness.

  19. Cooling Accessories for DSCs • Refrigerated Cooling System • RCS-90 • RCS-40 Self-contained, mechanical • -40/-90 to 550°C with excellent baseline performance • No frost, even with auto ampler • Liquid Nitrogen Cooling System (LNCS) • Fast cooling from 550°C to –180°C • Isothermal crystallization • Auto filling

  20. Autosampler • Automates analysis • 50-position tray including 5 references • Interruptible or sequential order • Automated calibration takes less than 3 minutes • Optical sensor guides placement • Available on Q 200 and Q 2000

  23. AVAILABLE MODEL FOR TGAs THE HIGHLY AUTOMATED Q5000 IR OFFERS UNMATCHED BASELINE FLATNESS, HIGH SENSITIVITY, ACCURATE TEMPERATURE MEASUREMENT, AND PRECISE CONTROL IN BOTH STANDARD AND HIGH HEATING RATE OPERATION. OTHER GREAT FEATURES INCLUDE VACUUM OPERATION, AUTOMATED CURIE POINT TEMPERATURE CALIBRATION, POWERFUL NEW SOFTWARE AND A 25-POSITION, SMART AUTOSAMPLER WITH A UNIQUE CONTAMINATION-FREE, SEALED PAN PUNCHING MECHANISM. IT IS CLEARLY THE BEST ANALYZER FOR COMPLEX TGA APPLICATIONS. TGA Q5000IR

  24. TGA Q 500 The Q500 is a research grade thermo gravimetricanalyzer, whose leading performance arises from aresponsive low-mass furnace; sensitive thermo balance, and efficient horizontal purge gas system (with massflow control). Its convenience, expandability and powerful, results-oriented software make the Q500perfect for the multi-user laboratory where a wide varietyof TGA applications are conducted and where futureexpansion of analytical work is anticipated

  25. The easy-to-use Q50 is a rugged, reliable, cost-effective TGA with many features of the Q500. It offers outstanding value as a compact, general-purpose thermo gravimetric analyzer that frequently outperforms competitive research-grade models. Its integral mass flow control, gas switching capability, and superb software make the Q50 ideal for academic teaching facilities or in industrial laboratories that need quality results at a modest cost.
