7 HKAS 2400 ANTI-STATIC FILM HAWKEYE HKAS 2400 Nylon Anti-Static Film is a specially designed transparent antistatic heat stabilized fluorescent orange nylon film, containing an internal organic antistat throughout the material which renders all surfaces of the film permanently static-conductive over a normal lifetime. Retaining its static-dissipating properties even when ultra-cleaned, HKAS 2400 can end the problem of particle attraction in clean room packaging of precision parts. Moreover, its heat stability permits dry heat sterilization of spacecraft and components within the sealed bag. HKAS 2400 eliminates the spark discharge hazard around electro-explosive devices and sensitive electronic components. Tests record HKAS 2400 bags can withstand 12 hours of exposure at 300 F ( C) without marked degradation where ordinary nylon browns and embrittles.

8 GUIDELINES OF CLEAN ROOM PACKAGING With the growing emphasis being placed on the control of contamination by the aerospace electronic and pharmaceutical fields, ever more stringent cleanliness requirements are being applied to finely machined parts, purified drugs and many other items whose satisfactory function depends on the virtual absence of foreign or particulate matter. Once such items have been cleaned to their fantastically low particle counts, it becomes necessary to package them in such a manner as to maintain this degree of cleanliness during storage, shipping, handling, testing and so on until final assembly or use. Experience and practice over the past few years have indicated that the best way to package such items, for reasons of weight and cube (the space taken up by a packaged item), is in flexible, heat sealable transparent plastic film which has been cleaned to the same stringent levels as the item to be packaged. Because the plastics used must possess very particular properties depending on their end use, many packaging films must be eliminated from consideration for various reasons. In all, only three films have stood the test of clean room usage and have become the films in general use. They are polyethylene, nylon and Aclar films. The following is a quick guide to their nature and uses. POLYETHYLENE: The generally accepted abbreviation for polyethylene is Poly. While poly is the first name of every plastic, the trade has applied it to the most common of packaging films. Poly is a pure hydrocarbon, available in a wide range of densities with generally low and broad melting ranges. It has a good inertness to most chemicals, with such notable exceptions as LOX and hydrocarbon solvents, and is inexpensive and relatively easy to clean and to seal. However, poly is soft and readily sloughs particles of its surface when abraded or flexed, so that its use should be confined to relatively non- 7 of 9

9 critical areas in clean packaging. These include overwraps for inner bags of nylon, for example, where the poly serves to provide a better moisture barrier than that supplied by the slough-resistant inner nylon bag. Poly bags are generally 6 mils thick for clean use. Plain poly, however, has been displaced to some extent by a pink polyethylene anti-static (HKAS1200) material, which prevents the static charges that attract dust to normal poly. NYLON: This film is the lowest-sloughing film available, generating fewer particles when exposed to abrasion and flexure than any known transparent film. Nylon 6 (the 6 is a generic reference to the number of carbons in its molecular chain units, as opposed to nylon 11 or nylon 6.6) is the established polyamide film in clean room use for packaging ultra-precise parts where particulate contamination must be held to the absolute minimum. The only field where nylon should be avoided as an intimate barrier, is the packaging of LOX service parts, and those destined for use with similar violent oxidizers, where the few particles sloughed from the surface of a nylon film or any other film, except a fluorocarbon, can constitute a potential explosion hazard when the part is placed in service in a LOS system. The other major fault of nylon is that it readily allows moisture vapor to pass through it, so that a second or outer bag made of poly, Aclar or a laminate should be used over the inner nylon bag, to provide the missing moisture vapor barrier, while the nylon prevents sloughing. In clean applications nylon film, 2 mils thick, is the most frequently chosen. Again an anti-static nylon, orange tinted (HKAS2400) is displacing normal nylon from clean rooms. ACLAR: Allied Chemical s trademark, for their fluoroholocarbon film is Aclar. Clear and transparent, inert to almost all chemicals and certified by NASA as LOS-compatible under their impact test (MSFC-SPEC- 106A) with liquid oxygen. Aclar is also the finest moisture vapor barrier available among transparent films. Aclar is the most costly of packaging films, but is among the least expensive of fluorine-bearing films, and is the least expensive LOX compatible film known. It is essentially a chlorotribluorethylene copolymer with small percentages of other fluorocarbons, unplasticized, specially tailored to give the 8 of 9

10 fantastic barrier properties described above. Three grades (Aclar 22C, Aclar 22A and Aclar 33C) are available. All are LOX-compatible, but the Aclar 33C is in most general use. Bags are usually made of 2 mil Aclar; roll stock may be 2 or 5 mil, as needed. Aclar cannot be tinted or rendered anti-static without affecting its properties adversely. All of the films mentioned above are widely available from manufacturers, they are offered only in a commercially clean grade. This is far too dirty in terms of today s technology too be suitable for clean room use. These films must be cleaned to the rigidly low particle counts required. HAWKEYE certifies t these levels to the user, offering clean roll stock, tubing or fabricated bags of a wide range of sizes, all to meet clean room requirements. Non-volatile residue (NVR) level is certified also, where applicable. For optimum protection of packaged parts, bags should be hermetically sealed, using heat. While poly may be sealed by constant heat or hot bar methods, Aclar and nylon, with their high and relatively sharp melting points do not lend themselves readily to this type of seal. Therefore, general practice dictates the use of thermal impulse sealers, capable of making adequate seals in ALL THREE clean room films. In both Aclar and nylon, such seals often exhibit a characteristic tendency to tear or to zipper along a line adjacent to the seal when severely strained. This is due to a line of increased crystallinity formed by the slow cooling or quench of the molten plastic in the insulated jaws of the sealer. It may be minimized and controlled by careful calibration of the sealer and keeping the cooling time as short as practicable; however, the phenomenon should be understood as the reason why seals in these films are not as strong as the film itself. In nylon, seals dehydrated of their plasticizing moisture by melting, may be restored to maximum flexibility by moistening or exposing to humid air for a few minutes. 9 of 9

11 HK900 BAGGING FILM HAWKEYE HK900 BAGGING FILM is a cast nylon, heat-stabilized film. This film has a melt point of 510 degrees F (265 degrees C) for increased stability in higher temperature applications where the film is exposed to elevated temperatures over prolonged time periods. HK900 is extremely flexible for cold conformability in bagging applications and hoot thermo-formability in vacuum forming. The clarity of the film optimizes visibility of contained products through the film. HK900 has good release qualities for ease of removal in curing applications. The thinner gauge provides improved cost-effectiveness and reduced waste with the loss of strength commonly associated with thinner films. HK900 BAGGING FILM contains no caprolactan.

12 HK800 BAGGING FILM HK800 BAGGING FILM is a modified heat stabilized blown nylon film, developed for temperatures to 350 degrees F (177 degrees C) for limited periods of time. This modified nylon film is generally softer and more flexible than standard nylon films. This film exhibits a lower elastic module while retaining its tensile strength and heat stability. The proper use of bagging films cannot be established by thermal properties along. Consideration must be given to conditions such as: the maximum temperature of cure, pressure used, condition of autoclave and length of time exposed. Forms Available: Roll Stock and Tubing Thickness:.002 and.003 Standard Color: Clear or Yellow Widths: 160 Maximum without seams Shelf Life: 1 Year (Depending on conditions) Suggested Use Temperature: 350 degrees F (177 degrees C) 2 of 16

13 HK800 CAST BAGGING FILM HK800 CAST BAGGING FILM offers some distinctive advantages not found in blown films. Cast film does not have suspended particles found in blown film and is more resistant to pin holes. This is due to the roller process used during the casting procedure. There is no shrinkage at 350 degrees F (177 degrees C), therefore it will not pull away from the vacuum bag sealant.

41 CARBON FABRIC Carbon fiber, also referred to as graphite fiber, is one of the strongest and stiffest reinforcements available. When properly engineered, carbon fiber advanced composites can achieve the strength and stiffness of metal parts at significant weight savings. In addition to the high strength-to-weight and stiffness-to-weight ratios, carbon fibers are thermally and electrically conductive, have very low thermal expansion coefficients and have excellent fatigue resistance. The impact resistance of carbon fiber laminates, however, is less than most other composite materials. When first introduced to the commercial market, carbon fiber reinforcements were referred to as HMG or high-modulus-graphite ; this was a reference to the high modulus of carbon fiber when compared with other available materials. Today that is somewhat of a misnomer. Standard yarn supplied to the commercial market is typically 530 KSI tensile strength, 34 MSI tensile modulus carbon fiber. Several yarn suppliers offer products with near identical properties considered interchangeable for all but the most stringent applications. High performance carbon fibers with increased tensile strength and/or modulus are available. 1 of 5

47 SONTECTOR 112 Ultrasonic Leak Detector Ultrasonic sounds in the range of 35,000 to 45,000 cps are detected by these instruments and converted to corresponding audible sound. This conversion retains the sound character so that little or no training is required prior to use. For example, the ultrasonic sound of a gaseous leak, when converted, has the same hissing characteristic with which we are all familiar. Solid-state circuitry is used in all models for long battery life and high reliability under field conditions. The units use a standard 9-volt transistor radio battery obtainable at most drug stores. Maintenance consists of periodic battery replacement and requires no special batteries or other parts. Leak Detection can readily be accomplished on both vacuum and pressure vessels. The hand probe or Sontector 112 is highly directional and is pointed at the area under test ad waved back and forth to locate the source of the leak sound by the sharp peak in audible intensity as the probe points directly at the leak source. Closer approach to the leak increases sound intensity so that a leak may be precisely located. In cases where several leaks or other ultrasonic noise sources interfere with this process, the sound concentrator may be slipped over the nose of the probe and the suspect area closely examined with its tip. The Sontector 112 is our most versatile instrument. It incorporates a loudspeaker and meter read-out and may be used with the accessory contact probe to evaluate the condition of machinery and internal operations. 2 of 3
