Saran, 763 table

There are several types of mesh available, and these are identified by mesh thickness, density, wire diameter and weave pattern. Table 4-9 identifies most of the commercial material now available. The knitted pads are available in any material that can be formed into the necessary weaves, this includes stainless steels, monel, nickel, copper, aluminum, carbon steel, tantalum, Hastelloy, Saran, polyethylene, fluoropolymer, and glass multi-filament. 

A nine-component composition has been tested in developing a new composite material. Three components were the binder of the composite material polyester EPX-279-1, polyester EPX-187-3 and styrene. These materials have been used as fillers ash, marble powder, glass microspheres, saran microspheres, wollastonite and powder made by grinding shells. Component properties with variation range of their proportions are given in Table 3.58. 

As Table III shows, where previously published values of CST are available, they are substantially equal to the values found in this study. However, the literature value assigned to Saran is the composite value for poly(vinyl chloride) (39) and poly(vinylidene chloride) (40). The literature value for silicone is the CST of poly(dimethylsiloxane) sorbed onto glass rather than that of cured poly (methyl hydrogen siloxane) which... 

The number of cycles in DHI 7 increases since oxygen is excluded, which, after activation to 102, causes destruction of the colored betaine 9.3 The number of Z cycles measured (e.g., in Saran) exceeds Z50 = 600. The Z50 equals the number of cycles leading to 50% of the original extinction of the colored form (Z 80 equals 80% of the original E). Similar matrix effects have been observed with spiropyrans.57 Typical values are given in Table 6.4. In a poly(vinyl butyral) (TrosifolR) matrix, the number of cycles for DHI 7 —> 9 exceeds Z50 = 50 00.3-7... 

Polyvinylidenechloride, PVDC, was discovered in 1838 by Regnault but commercialized 100 years later as Saran . The commercial PVDC is modified by the incorporation of either 15-20 wt% vinyl chloride, or 13 wt% vinyl chloride and 2 wt% acrylonitrile. PVDC blends are summarized in Table 1.32. 

Hoffman-Weeks plots have also been drawn for several other amorphous/crystalhne miscible blends, such as PVDF/PEMA [Eshuis et al., 1982], PEG/PMMA [Martuscelh, 1984], PCL/SARAN [Zhang and Prud homme, 1987], as well as for some miscible blends containing two semicrystalline components, PCL/PC [Jonza and Porter, 1986] and PCL/Penton [Guo, 1990]. Table 3.10 represents equilibrium melting points derived from... 

Saran is resistant to oxidants, mineral acids, and solvents. In applications such as plating solutions, chlorides and certain other chemicals, polyvinylidene chloride is superior to pol)rpropylene and finds many applications in the handling of municipal water supplies and waste waters. Saran is also resistant to weathering and UV degradation. Refer to Table 2.33 for the compatibility of PVDC with selected corrodents. Reference [1] provides a more comprehensive listing.

Saran is stable in water and withstands high temperatures. It is supplied as films or woven and it is extensively used for upholstery in household or transportation. It is found in interior clothing, suits, mgs, and tire reinforcement. Rayon suffers from high water absorbency and is frequently used as a blend with other fibers. An interesting product is found in PET (recovered from bottles) as a textile for interior and insulating clothing. Acetate is found as a blend in fine clothing and upholstery. Artificial fibers like Nylon and others can be used as a reinforcement to plastomers. A typical breakdown is shown in Table 6-2. 

PVC), and Saran (a copolymer of PVDC and PVC) charcoals but was almost half of the amount of CO2 evolved in the case of polyfurfurylalocbol (PF) and urea fonnolede-loyde (UF) charcoals (Table 1.6). The base neutralization capacity decreased on evacuation, and the decrease at any temperature corresponded to the amount of CO2 evolved at that temperature. Furthermore, the temperature interval over which the drop in base neutralization occurred appears to be the same (Figure 1.8) as the temperature interval over which CO2 was evolved from the carbon sample. 

Feed Stocks. Seria, Mukhanovskaya, Minas, Gach Saran, Kuwait, Khafji and Duri crudes were subjected to the pyrolysis. Several distillates and the topped residue from Kuwait crude were also employed to cover the wide variety of hydrocarbon compositions of feed stock with which the pyrolysis results should be closely correlated. General properties of these feed stocks are given in Tables I and II, respectively. 

Table V summarizes the sulfur inspection data for Kuwait, Khafji, and Gach Saran crude oil pyrolysis.

Saran is the trademark of Dow Chemical for their proprietary polyvinylidene chloride resin. It has a maximum allowable operating temperature of 175°F/81°C. It is used to line piping as well as vessels. Refer to Table 3.13 for the physical and mechanical properties of Saran.

Halogen-substimted alkenes can also polymerize. These molecules are polar, so the resulting polymer has dipole attractions in addition to induced dipole forces. A familiar example of such a polymer is Saran, the food wrap that clings to itself. Saran is a copolymer because it is made from two monomers, CH2=CHC1 and CH2=CCl2. The attractive forces between Saran polymer films come from the dipoles caused by the carbon-chlorine bonds. Table 21.6 lists more ethylene-based monomers that give addition polymers.
