3. What is Microporous Insulation? Composition: Amorphous Silica Particles Metal Oxide Powders Non-RespirableFibers Cold pressed to density Density effects rigidity & thermal conductivity Blanket – Panel – Board - Pipe Faced and fabricated

4. MICROTHERM® – Key Features MICROTHERM® is a microporous insulation that blocks the transfer of heat even more effectively than still air. Very low thermal conductivity, even at high temperatures. Non-combustible, inorganic material. Fully hydrophobic grade available for outer layers. No respirable fibers. No known health hazards within prescribed operating temperatures. Environmentally friendly. Engineered glass cloth facing minimizes dust Not an Aerogel product. In addition to this, the MICROTHERM Group provides unequalled world wide sales support, design assistance, and customer service.

5. ASTM C-1676 – Product Grades & Types ASTM “Grades” define: 1) The operating temperature limits 2) Water repellency (Hydrophobic) characteristics Note: Water repellency (Grade 2B) will begin to vanish at temperatures above 250 °C then the product will perform as a non-repellent grade

6. ASTM C-1676 – Product Grades & Types ASTM “Types” define product form Type 1 – Rigid Products ASTM Terminology = “Board” For Flat or Planar Surfaces Microtherm Products Microtherm Standard (SG )Panel Microtherm Hydrophobic Panel Microtherm Standard (SG) Block Microtherm Board Panels are encased in E-Glass fabric Board and Block are unfaced or shrink-wrapped for handling Thicknesses up to 2” (up to 4” in optional size)

7. ASTM C-1676 – Product Grades & Types Type II – Flexible ASTM Term = “Quilted” Blanket type products Flexible in 1 or 2 directions For Cylinders or Irregular Surfaces Microtherm Products Microtherm Standard Quilt Microtherm Hydrophobic Quilt Microtherm Overstitched Microtherm Slatted Thicknesses Quilted and Overstitched – Up to ½” Slatted – Up to 1”

8. ASTM C-1676 – Product Grades & Types Type III – Pipe ASTM Term = “Molded Pipe Section” Pre-formed Rigid Pipe Sections Grooved longitudinal seams minimize heat loss NPS Pipe Sizes from ¾” to 28” Microtherm Products Microtherm MPS Thicknesses Always supplied at 1” (25mm) Thick

9. ASTM C-1676 – Additional Requirements Thermal Conductivity Guarded Hot Plate (C177) Heat Flow Meter (C518) Pipe Apparatus (C335) Refractory (C201) Linear Shrinkage (C356) Compressive Resistance (C165) Water Vapor Sorption (C1104) Surface Burning Characteristics (E84) Flame Spread Smoke Developed Index Corrosiveness (C665) ASTM Standards for workmanship, certification, etc.

10. Benefits –Why use Microporous Insulation? Conventional Insulations MICROTHERM has the lowest Thermal Conductivity of any High Temperature Insulation MICROTHERM !

11. Benefits –Why use Microporous Insulation? Personnel Protection Requirement – Outside Surface < 60°C Ambient 25°C 56°C 6” NPS 650°C 54°C 55% Less Weight - 28% Less Energy Loss - 46% Less Volume (OD)

12. Benefits –Why use Microporous Insulation? Equivalent Heat Loss Requirement Ambient 25°C 370 W/m 6” NPS 650°C 353 W/m 70% Less Weight - 5% Less Energy Loss - 52% Less Volume (OD)

13. Benefits –Why use Microporous Insulation? 1000 oC (1832 oF) Continuous use temperature 3 to 4 X More efficient than conventional insulation resulting in: Less Space = Less wind load Less to ship Closer pipe spacing Less jacketing Less Weight = Lower pipe loading Easier to carry and install Save Energy = Less process heat (Gas, Electric etc.) Less heat loss (smaller diameters) Fewer CO2 equivalents, GHGs Better Control = More homogeneous temperature Improved yields or process quality Excellent compressive strength minimizes insulation damage Friendly and easy to handle glass facing Ready to install and easily fabricated product shapes INSULATION DAMAGE

14. Applications – Where & When Should it be used? BP Chemicals (Grangemouth, UK) – a high temperature expansion loop alongside perimeter fencing – 50 mm of MICROTHERM®MPS was used instead of 200 mm of mineral fibre.

15. MICROTHERM® Application – Vessel on Load Cells Load Cell Application Constant Weight Monitoring Required 1200 F Process Temperature Yield significantly effected by temperature variations Compression Resistance Weight Comparison: Calcium Silicate 11,500 lbs Microtherm 2,350 lbs ~80% Weight Reduction Support Lug Load Cell

17. MICROTHERM® Applications MICROTHERM®offers the best thermal insulation protection in the smallest volume. Wherever SPACE, WEIGHT, or ENERGY are a concern: Weight Examples - Excessive Pipe/System Loads Reduction in Pipe Hangers Installing Insulation on Elevated Platforms Vessels with Load Cells Space Examples - High Wind Loads Congested Piping More Pipes on a Rack Maintenance Access Revamps – Less Energy in Existing Space Energy Examples- Kyoto Regulation Reduced GHGs, NOx, CO2, CE Reduced Fuel Consumption, Burner Use Other reasons include – MICROTHERM®systems are clean and safe to handle. MICROTHERM®systems are much smaller in volume reducing transport and labor.

19. Marker pen or pencil.

20. A tape measure or a template.

21. A straight edge for straight cuts.

23. Sodium Silicate adhesive plus small brush.

24. Either – strips of glass cloth. - pre-cut tape. - self adhesive glass cloth or aluminium foil tape.

25. Fabrication – How do I work with it? – Straight Cut Clearly mark the line of the cut on the panel. Use a straight edge. Apply pressure alongside the cut by pressing down on the straightedge. Cut firmly making sure that the blade penetrates the lower glass cloth covering. Blow off any fine dust. Cut edge is ready for sealing.

27. Carefully follow the line of the cut making sure that the knife blade cuts through the lower glass cloth layer.

28. Separate the sections and blow off any slight dust residue.

30. Fold it neatly around the cut edge.

31. Neatly cut and fold the corners in the sequence shown in the photographs.

32. For less demanding applications, self adhesive tapes may be used.

34. Apply Sodium Silicate adhesive.
