The thermoplastic elastomers (TPE) are a new class of the polymeric materials, which combine the properties of the chemically cross-linked mbbers and easiness of processing and recycling of the thermoplastics [1-8]. The characteristics of the TPE are phase micrononuniformity and specific domain morphology. Their properties are intermediate and are in the range between those, which characterize the polymers, which produce the rigid and elastic phase. These properties of TPE, regardless of its t5 e... 

The properties of engineering thermoplastics span a wide range, and there are many overlapping situations among resins. To select the right polymeric material for a specific application is a hard job because the forest of commercial polymers has become so crowded. Books have appeared to guide the materials engineer in the selection of thermoplastic materials, with the help of a dedicated software (6). 

Electrical properties of materials are described by their behavior in the presence of an electric field. Basically, the response of any material to an electric field can be separated into two main parts dielectric response and electrical conduction. Polymer-based materials with good conduction properties have been the subject of fundamental scientific interest due to their tremendous potential in various applications (Gul 1996). Even though most polymeric materials are not conductors of electricity, they are easy to fabricate into complex shapes at a reduced expense. In particular, thermoplastics are moldable or extrudable into various shapes and sizes (Thomas et al. 2015). Besides this, the specific weight of industrial standard... 

Other resins which find use as tackifiers for Neoprene include polyterpene resins, hydrogenated wood rosins, rosin esters, and couma-rone-indene resins. Chlorinated rubber is used to promote metal adhesion and as an ingredient of two-component adhesives. Poly-alpha-methyl styrene is used to obtain better specific adhesion to thermoplastic rubber. The compatibility of Neoprene with resins and other polymeric materials is detailed in Ref. 11. 

Quite a variety of different techniques are employed in the forming of polymeric materials. The method used for a specific polymer depends on several factors (1) whether the material is thermoplastic or thermosetting (2) if thermoplastic, the temperature at which it softens (3) the atmospheric stability of the material being formed and (4) the geometry and size of the finished product. There are numerous similarities between some of these techniques and those used for fabricating metals and ceramics. 

Nylon A class of synthetic fibres and plastics, polyamides. Manufactured by condensation polymerization of ct, oj-aminomonocarboxylic acids or of aliphatic diamines with aliphatic dicarboxylic acids. Also rormed specifically, e.g. from caprolactam. The different Nylons are identified by reference to the carbon numbers of the diacid and diamine (e.g. Nylon 66 is from hexamethylene diamine and adipic acid). Thermoplastic materials with high m.p., insolubility, toughness, impact resistance, low friction. Used in monofilaments, textiles, cables, insulation and in packing materials. U.S. production 1983 11 megatonnes.
