Some specialized uses of PETN are summarized below. Expendable cartridges for small arms are made by coating unglazed grains or single base smokeless powder with PETN, spraying with plasticized thermoplastic binder and compression molding to the desired shape (Ref 99). Tucker et al (Ref 85) describe a spark detonator without primary expls. Secondary...

In a recently published extensive survey 23) consideration is given to main trends relating to development and improvement of modern equipment for mixing and plasticizing thermoplastic materials. Discussion below will be restricted to facilities for thermosetting plastics. 

Pressure-sensitive labels can be applied to most materials (wood, plastic, metal, glass, paper, and board). As the adhesives are resin-based (plasticized thermoplastics), migration problems can occur when they are applied to certain plastics (e.g., PVC, LDPE). 

John Hyatt was the first to make plastics. He made celluloid in 1868. Leo Baekeland made bakelite. Synthetic plastics are made from petroleum products. There are two types of plastics thermoplastics and thermosetting plastics.

Fig. 6.27 Comparison between experimental pressure profile for plasticized thermoplastic resin (34) and theoretical pressure profiles for n — 1 and n — 0.25 calculated by Kiparissides and Vlachopoulos (35). The theoretical curves were calculated both by finite element method and analytically by way of Gaskell type models, as discussed in this section, giving virtually identical results.

In comparison to bulk plastics, thermoplastic polymethylmethacrylate (PMMA) is much more expensive. Its particular characteristics are clarity, hardness, low absorbance and resistance to aqueous solutions, acids, alkalis, carbon dioxide and fat. It is attacked or dissolved by polar organic solvents. The world-wide use of PMMA in 1997 was ca. 1.2 x 106 t, principaly for optical articles in cars and buildings and glazing material in aircraft. Typical food contact articles are dishes, cups and silverware. In addition it has orthopedic and denture uses. 

Retardants are mainly used as additives for plastics, particularly those used in the manufacture of electrical and electronic equipment. FRs are added to circuit boards, cables, coimectors, plugs, and house component devices. These compounds are used in the production of engineering plastics, thermoplastic and elastomeric elements, and insulation. Flame retardants can also be found in furniture, mattresses, carpets, curtains, clothing (mainly protective or sweatshirts for children), and polymeric materials used for the production of cars, buses, airplanes, and military equipment. FRs have been used wherever material must meet safety standards regarding flammability [87].

The information is limited to the most important materials, metals, plastics, (thermoplastics, thermoset materials, foams), ceramics, glass and their possible combinations. For papers, cardboards, wood, rubber polymers, usually physically setting systems (solvent-based, dispersion, hot-melt adhesives) are utilized. In these cases, the adhesive selection with regard to the manufacturing conditions and demands is of less problematic nature.

Low-modular composite materials based on plasticized thermoplastics belong to a group of sealing materials that stands in between structural and sealing materials. The fact that these materials display elasticity modulus, hardness and toughness close to the initial polymer allows their use in parts that are to bear considerable mechanical loads and other effects, and in particular in sealing joints of machines and equipment [123]. 

Rubber-free inhibited sealants based on plasticized thermoplastics have been developed for oil and gas pipelines. A non-drying plastic material [10] in the form of a gel is based on PE and a tar of mineral and vegetable oils, which is used as a plasticizing and anticorrosion additive. PE gels are filled with fibers and powder particles to improve the strength of sealing layers [11]. For PE-compatible Cl a synergetic mixture of potassium and...
