Gelatin plasticizers

Kinetite (Kinetit or Kinenite-Swiss). One of the earliest gelatinous (plastic) expls which contd no NG. It was patented in 1884 by Petry and Fallenstein and was used extensively at the end of the last century in Ger and other European countries. It was prepd by gelatinizing Nitrobenzene or Nitrotoluene with Collodion Cotton, and impregnating this plastic mass with sulfur, K chlorate and other ingredients. Sulfur was later replaced by Sb penta-sulfide. Its compn was NB 16.0 to 21.0, Collodion Cotton 0.75 to 1.0, K chlorate 82.5 to 75.0, Sb2Ss and/or K nitrate 3.0 to 1.0%. The function of the Sb pentasulfide was to render the explosion more regular and more complete... 

The (C) group included gelatinous (plastic) compns which contd approx 30% NG-NC gel and had densities of up to 1.7g/cc. They were suitable for blasting hard rock. Wetter-Arit A, w -Barbarit, W-Carbonit, W-Nobelit and W-Wasagit belonged to this group... 

The wet gel mass is manufactured by mixing together and melting, under vacuum, the gelatin shell ingredients (gelatin, plasticizer, water, colorants and sometimes opacifiers, flavors, and preservatives). At the encapsulation machine (Fig. 5), molten gel mass flows through heated transfer tubes and is cast onto... 

Disflamoll. [Bayer Mites/Polysar Rubber] Phosphates flame retardant, gelatinizing plasticizer ftxr PVC and cellu-losic us for extruded and inj. mrilded parts, mechanical foam, belts, imitation leathff, coatings, cable sheathing. 

It is well established that the extrusion of proteins is a potential for obtaining edible films on a large scale [41]. For these authors, the incorporation of polysaccharides and inclusion of nanoparticles in these films tend to improve their mechanical properties. Park et al. [42] studied bioplastics made from extruded gelatin plasticized with glycerol, sorbitol or a mixture of both. In this study, they discard sorbitol as a plasticizer because of low flow in the extrusion of the material. 

Regardless of the variations in the methodology chosen for the components addition in the extruder, it is important to note that the filler can be dispersed in starch during the gelatinization extrusion process. It is advantageous to use a twin screw extruder with multiple inlet ports so that gelatinization, plasticizer, and filler...

The main use of lead metaborate is in glazes on pottery, porcelain, and chinaware, as weU as in enamels for cast iron. Other appHcations include as radiation-shielding plastics, as a gelatinous thermal insulator containing asbestos fibers for neutron shielding, and as an additive to improve the properties of semiconducting materials used in thermistors (137). 

A typical recipe for batch emulsion polymerization is shown in Table 13. A reaction time of 7—8 h at 30°C is requited for 95—98% conversion. A latex is produced with an average particle diameter of 100—150 nm. Other modifying ingredients may be present, eg, other colloidal protective agents such as gelatin or carboxymethylcellulose, initiator activators such as redox types, chelates, plasticizers, stabilizers, and chain-transfer agents. 

Nobel invented gelatinous dynamite in 1875 by accident. He investigated the effect of nitroglycerine on the collodion (nitrocellulose in a mixture of ether and alcohol) that he used to treat a cut finger and found that it produced a tough plastic material with adjustable viscosity and high water resistance. 

Suspension polymerization produces beads of plastic for styrene, methyl methacrviaie. viny l chloride, and vinyl acetate production. The monomer, in which the catalyst must be soluble, is maintained in droplet fonn suspended in water by agitation in the presence of a stabilizer such as gelatin each droplet of monomer undergoes bulk polymerization. In emulsion polymerization, ihe monomer is dispersed in water by means of a surfactant to form tiny particles held in suspension I micellcsK The monomer enters the hydrocarbon part of the micelles for polymerization by a... 

Nauchoff s Explosives. Low freezing plastic expls patented prior to WW1 by S.A.S. Nauchoff of Sweden. It was claimed that they were equal to Dynamites in performance. Examples are (1) Liq TNT (gelatinized by dissolving 4p of NC in 96p of liq TNT, called flussige Tri in German) 31, Amm perchlorate 43 ... 

Polyethyleneglycol ethers. These compds are recommended as addns to gelatin Dynamite in quantities of about 0.4% to improve plasticity. They usually.contain at least 8 linear carbon atoms and at least two adjacent ethyleneoxy groups... 

Gelatin B from cow bone was supplied by Britannia Lab Argentine with isoelectric point of 5.10. Gelatin was dried and sealed in zip plastic bags and then kept in desiccators. Finally, gelatin was dissolved in distilled water preparing a solution of 0.25, 0.5, 0.75 and 1% (wt.). 

Capsules— These are primarily intended for oral administration and are solid preparations with hard or soft shells comprised of gelatin or hydrox-ypropyl methyl cellulose and small amounts of other ingredients such as plasticizers, fillers, and coloring agents. Their contents may be powders, granules, pellets, liquids, or pastes. 

Photographic film is a transparent plastic coated with a gelatinous film containing a silver salt, usually AgBr. When the film is exposed to light, individual photons absorbed by the Ag ions cause an electron-transfer reaction that produces neutral silver atoms ... 

Either type of gelatin may be used, but combinations of pork skin and bone gelatin are often used to optimize shell characteristics [15,16], Bone gelatin contributes firmness, whereas pork skin gelatin contributes plasticity and clarity.
