The new process operates at 500-600-psi. pressure. This contrasts with the 10,000-30,000 psi. needed in the conventional low-density process. A new way to apply colored coatings to glass containers was unwrapped this week at. the American Management Assn.'s Packaging Exposition and Convention in Chicago. The new process, called Color Guard, is still under development at Glass Containers Corp. (Fullerton, Calif.). But it promises, says GCC, to be more economical than the use of colored glass (which requires special glass furnace runs or feeder melts). And it should cost considerably less than existing cold-color techniques, which typically cost . SI/gross of container treated. Color Guard puts a colored epoxy* resin coating on the container at the cold end of the production line (after forming and annealing). The process can be used to apply colorless ultraviolet-light-screening coatings as well GCC feels the method should cut the minimum economical production run in making colored containers. And it says the epoxy coat should protea the bottles from abrasion, increase lubricity--thus making them easier to handle oo the filling line. Color Guard will be well-suited to throwaway containers, says GCC Returnable bottles may pose a big problem, because of degradation of the epoxy coating under the caustic soda wash used on returnable*. Chemical development oo the process was done by Stanford Research Institute. GCC is working on mechanical aspects (including alternative applica tion methods) at its Knox, Pa., plant. It is not yet ready to estimate when the system wiD be ready for sale or license. A new porcelain enamel coating Is being tested by Ferro Corp. (Cleveland). Of undisclosed composition, it is said to act catalytically to promote oxidation at temperatures over 300 F. Original testing centers on coatings for self-cleaning household ovens. But Ferro sees potential applica tion in the CPI, is studying its performance under severe conditions. The chemical Industry has Improved Its safety record slightly. The manu/acturing Chemists' Assn, figures for '68; on frequency rate for disabling accidents, 3.27/million man-hours worked; for severity, 4S5 work days lost (or charged as lost) because of injuries/million man-hours worked. The 3.37 and 485 compare with 3.3 and 524 m *67. MCA's figures cover 115 reporting companies. Composite figures for all industry are not yet available for *68. MCA points out, however, that to figures on frequency have been consistently about ooe-half those for all-industry as compiled by the National Safety Council. The chemical industry figures leave no room for complacency, however. The frequency rate has not changed much over the past 10 yean, so companies will have to work harder than ever to improve the industry standing. 7t CHEMICAL WEEK April If. JM* TECHNOLOGY Newsletter 0108 V CHEMICAL WEEK APRIL 19, 1969 A new high-innptraturt fiber fa being introduced by Carborundum this week. It's Kynol, a phenolic said to combine some of the best features of inorganics (e.g., glass) rrr*"^ fr f[ Trr**^0 '{""tir1* it can withstand oxidizing atmospherpS^of 300 F for extendedperiods) It is not bothered by exposure to an oxyueetylene torch for brief periods/flt eventually chars but doesn't bum.) Ana retains shape and ex hibits minimal shrinkage. ReasoA: in the burning process, the fiber becomes carbonized (60?I yield). Moreover, the evolution of gases (steam and carbon dioxide) provides a layer of insulation and the carbon that's formed dis- * sipates heat through radiation. At the same time, says Carborundum, the new fiber has good tensile strength (45,000 psL), moisture regain (comparable to nylon), can be blended with other fibers (polyesters, wool, etc.), and shows excellent corrosion resistance. % It is now bejng made in "hundreds of lbs./week" lots but produc tion will soon be on a "thousands of lbs./week scale." Kynol is selling for SS/lb. now, but the company sees no reason why it shouldn't eventually sell for less than $2/lb. Carborundum will not discuss chemistry except to say the product is amorphous (no X-ray pattern can be detected) and that the phenolic units are cross-linked in a novel manner. This leaves a number of doors open, of course. It may use a cross-linking agent like maleic acid, for example, In making phenolic resins, a number of hydroxyl groups are formed in the inter mediate products. Addition of maleic (or similar cross-linkers) might produce a polymer that would give a desirable compromise between the rigidity' required for strength and temperature resistance and the elasticity needed for a fiber. Carborundum is looking at a number of markets. It thinks Kynol could find military applications. And it might be used for fire-fighting gar ments, filters or other industrial applications as well as in furnishings for insti tutions or the home. It is now being made as a 1 Vi -in. (1.7 denier) staple fiber. Carborundum expects to have Kynol available eventually in different denien, as crimped staple and as a continuous filament One potentially important drawback is the dark color. Carborundum describes it as "golden hued." Sam ples shown, however, are rust)' red. (Dark color is, of course, typical of pheno lic resins.) So products are limited now to dark shades. Carborundum, how ever, reports some success in bleaching. . A new lew-pressure process for making low-density polyethylene has been successfully piloted by Phillips, is now being put through commercial paces. The method, says the company, is economical, can be used to make medium- and high-density polyethylene, as well as low-density material This gives it a flexibility hard to match. Phillips developed one of the pioneering routes to high-density (low-pressure) polyolefins using a chrome oxide catalyst system. The new process, it says, employs a catalyst in the same family. .Phillips completed a 7f-miIlion Ibs./year plant last year at its Adams 01084 '! / An organic fiber that beasts bettor flams resistance than any other textile material has been unveiled by Carborundum Co. It neither bums aor melts, and it eves resists a <500 F. oxyacetyleae flame for several minutes, before becoming a char with relatively small loss of volume. The charring reaction gives oS gases that are aoncombustible (such as carbon monoxide, orbon dioxide and water vapor), which in effect ablath-ely protects the onexposed layers of flber. What's more, the material is inert to almost aD organic solvents and nonoxidizing acids. Called Kynol, the flber consists of phenolic units "eoss-linked in e novel manner.** At present, it is evailabla b its natural deep-copper color, or dyed bto deep colors Including red, Mne or green; Carborundum hopes to also find ways to impart pastel shades. The company is selling the fiber as l%-in.-long staple with 114-micron die, and totends to also bring a crimped staple and a continoous-Slament yarn to market within the coming year. Conditions are now being established for processing die fiber on various kinds of textile equipment Carborundum thinks that at high-volume consumption, die cost wiQ be in the renge of low-price synthetic fibers. The material might not only be used alone but also as a blend with other fibers, including cotton or wool A wide range of applications has been suggested, from airsaft insulation to corrosive-liquids filtration, to protective bdustrlal clothing, to blankets and drapes for institutions or / w.
