Advanced engineering thermoplastics

Advanced Thermoplastics Materials. Thermoplastics and linear plastics of finite molecular weight that can be fabricated into very complex stmctures by hot melt or injection mol ding are different from the thermoset materials that require cross-linking to build up infinite molecular weight to form network (cross-link) stmctures. Advances in thermoplastic engineering materials include amorphous thermoplastics, crystalline thermoplastics, Hquid crystal thermoplastics, and fluorinated thermoplastics (see Engineering plastics).

As can be deduced from plant purchases, the PRC is still at the formative stage where emphasis is on producing only the most basic petrochemicals. No plants were purchased for producing dibasic acids (phthalic and maleic anhydrides, etc.) and fluro-carbon or tetrafluoro ethylene or some of the advanced engineering plastics like ABS polyacetals, polycarbonates, polyimides or any other unsaturated polyesters. Another important area of low Chinese activity is thermoplastics for space and defense applications. ...

The area of advanced engineering thermoplastics is a good example. Companies have been inventing new engineering thermoplastics for the last twenty years. 

Beginning with Union Carbide s polysulfone around 1972, no less than ten to twelve advanced engineering thermoplastics have been commercialized by as many as fifteen companies throughout the world. While total world capacity may have reached 140 million pounds, world consumption for 1989 has been estimated to be only sixty million pounds. 

Inorganic whiskers, a kind of single crystal fibrous or needle-like material that appeared in recent years, are used to reinforce thermosetting resin, thermoplastic resin, rubber, metal, and ceramics through filling and to prepare advanced engineering plastic, composite materials, adhesive, sealant, and paint. The excellent performances of inorganic whiskers have led to their wide application as composite materials- ...

Engineering polymers generally comprise a high performance segment of synthetic plastic materials that exhibit premium properties. In this paper, engineering thermoplastics developed for advanced applications, and particularly for enhanced thermal stability are considered. 

Recycling is particularly important for the building civil engineering market, the sector with the second-largest consumption of thermoplastics. Unfortunately, plastics recycling presents technical and economic difficulties and is less advanced, industrially, than that of metals or glass. 

This volume on Polyolefins and Styrenics is the first part of a four-part set on Handbook of Engineering and Specialty Thermoplastics. The other three parts, to be published in late 2010 and 2011, are on Polyethers and Polyesters Nylons Water Soluble Polymers. The aim of the Handbook is to keep the practitioner abreast of the recent developments in these subfields as well as to equip the advanced student with up-to-date knowledge as he/she enters the industrial arena.
