An ideal choice for jackets, pants, gloves, hats, comforters, and pillows, Sorona® used in insulation provides lightweight breathable warmth, outstanding fill power performance, and great compression and recovery. In comparing insulation made with Sorona® to insulation made with premium, branded polyester, Sorona® outperforms the premium, branded polyester insulation in many key categories. Take a look at the following report to learn more. THERMAL RESIS T ANC E Sorona® insulation displays an improved ability to retain heat compared to premium, branded polyester insulation. This means that when using the same amount of filling by weight, the garment with Sorona® insulation will keep you warmer.

(A) Polytetrafluoroethylene: Dupont's Teflon Rod. (B) Silver Chloride: 99.992 Per Cent Minimum Purity, Reagent
THE MELTING AND PYROLYSIS OF TEFLON AND THE MELTING OF SILVER CHLORIDE AND IODINE UNDER HIGH PRESSURE* BY 1IMASAAKI TAMAYAMA, TERRELL N. ANDERSEN, AND HENRY EYRING INSTITUTE FOR THE STUDY OF RATE PROCESSES, UNIVERSITY OF UTAH, SALT LAKE CITY Communicated January 9, 1967 The melting temperatures have been determined for a wide range of substances as a function of pressure. In the present work, Teflon (polytetrafluoroethylene) was investigated up to 30 kb and the decomposition temperatures, and the melting temperatures of silver chloride and iodine were determined up to 30 kb and 20 kb, respectively. General Technique. -The pressure was generated with a piston-cylinder type press, the details of which can be found elsewhere.'-3 A typical high-pressure furnace is shown in Figure 1. The temperature of the sample was varied by means of an electrical resistance graphite heater placed in the high-pressure furnace. Electricity was applied to the heater at a constant rate. Two Alumel-Chromel thermocouples were set in the furnace, one for measuring the temperature of the sample and the other to be used in making a differential thermal analysis (DTA). The slight change of electromotive force of the thermocouples due to pressure4 was not cor- rected for in the present work. The high-pressure furnace used in the present work consisted of materials such as talc, pyrophyllite, graphite, and Teflon, which served as solid pressure transmitting media. The calculated pressure at the bottom of the moving piston is not trans- mitted unchanged through such highly viscous pressure transmitters as are used in our high-pressure furnace.

Torched Penny Repair Paint Application Guideline-Admila
xB RS 4.0 is out and looks to be a hit with our customers. We have noticed some chatter on the web regarding the special Torched Penny paint and its repairability. I wanted to provide you with some first hand information and dispel some of the rumors. • Yes, the paint does cost more than normal paint Why = It is due to the special color changing characteristics (high pigmentation) of the paint • No, you do not need to re-paint the whole car if you get into an accident or get a scratch. Why = Due to the color changing paint it is actually easier to blend and match than traditional paints (its harder to see the painting mistakes). Spot painting instructions are attached. • No, the color is not difficult to match Why = Due to the color changing paint it is actually easier to blend and match than traditional paints (it’s harder to see the painting mistakes). • Yes, there are paint companies offering this paint for repairs. I am pleased to announce that all of the paint companies listed below have successfully achieved color matches for the Scion xB 3R2 "Torched Penny" color. • PPG - 10/6/06 - completed with successful color match • BASF - 9/4/06 - completed with successful color match • Sherwin Williams - 10/17/06 - completed with successful color match • DuPont - 11/10/06 - completed with successful color match • Akzo Nobel - 11/09/06 - completed with successful color match See attached paint repair application guide that was produced by Nippon Paint, the manufacturer of Maziora. See attached marketing information that was created by Nippon Paint that helps to explain the Maziroa paint (please excuse some of the grammar, the info is good though).

Kevlar Cut Protection Testing
DuPont™ Kevlar ® THE SCIENCE OF CUT PROTECtiON Industry standards groups have made tremendous progress in testing and measuring the cut protective performance of gloves and apparel. DuPont has been a pioneer and active contributor to these efforts. It is now commonplace to have a wide range of performance data available for any protective apparel under consideration. Although the availability of cut protection performance information is widespread, it is important to understand the different test methodologies in order to interpret the data and draw accurate conclusions. This guide is designed to help specifiers of protective apparel make informed decisions about cut protective apparel performance. As a result, specifiers should take the time to better understand the sources of information and the critical factors that influence cut protection. Recent changes to some of the test methods make this imperative. The keys to cut protection Basis weight (oz/yd2) Cut protection is a combination of many factors, not just Defined as the fabric weight per unit area, not the overall the material of construction. Therefore, all of the following glove weight. The higher the basis weight, the higher the factors should be carefully considered when assessing cut resistance because there is more material present. the cut-resistant properties of a glove, particularly if you are developing a product specification: Fabric construction Defined as the details of structure of fabric. Includes such Material of construction information as types of knit or weave, threads/stitches (Kevlar®, leather, cotton, steel, etc.) This has the per inch. This can affect yarn mobility and sample greatest impact on the cut resistance of personal thickness, which can affect cut resistance.
