Thermoplastics and thermosetting resins

Currendy, epoxy resins (qv) constitute over 90% of the matrix resin material used in advanced composites. The total usage of advanced composites is expected to grow to around 45,500 t by the year 2000, with the total resin usage around 18,000 t in 2000. Epoxy resins are expected to stiH constitute about 80% of the total matrix-resin-systems market in 2000. The largest share of the remaining market will be divided between bismaleimides and polyimide systems (12 to 15%) and what are classified as other polymers, including thermoplastics and thermoset resins other than epoxies, bismaleimides, cyanate esters, and polyimide systems (see Composites,polymer-matrix-thermoplastics). 

To process formulations, thermoplastic and thermosetting resins are used. For thermoplastic resins such as VAAR, the binder is dissolved in a solvent and then mixed with Mg and sodium nitrate until the solvent is evaporated. This formulation can then be stored and used whenever needed. No curing is required after consolidation. On the other hand, the epoxy-PS blend is mixed with an amine... 

MixedPhosphonate Esters. Unsaturated, mixed phosphonate esters have been prepared from monoesters of 1,4-cyclohexanedimethanol and unsaturated dicarboxylic acids. For example, maleic anhydride reacts with this diol to form the maleate, which is treated with benzenephosphonic acid to yidd an unsaturated product. These esters have been used as flame-retardant additives for thermoplastic and thermosetting resins (97). 

Plastic foams are manufactured from thermoplastic and thermoset resins in various forms. The main pitfall in joining plastic foam is that of (1) causing the foam to swell or collapse by contact with a solvent or monomer and (2) having the adhesive alter the properties of the foam through its absorption into the foam. Adhesion and joining are usually not a serious problem because of the porous nature of the foam. 

In addition to the various welding techniques, adhesives may join plastic parts. Both thermoplastic and thermosetting resins may be bonded and parts made of different resins are often treated in this... 

It should be recognized that almost every thermoplastic and thermoset resin may be produced today in cellular form by means of the mechanisms and processes cited above. The physical properties of the foams reflect in many ways those of the neat polymers, taking into account the effects of density and ceU geometry.

With the fast developments in the plastic industry, some of the lesser known plastics will either find future usage or already be used for devices, general medical instruments and apparatus or as implant aids. Certain plastics now involve alloys, i.e. mixtures of thermoplastics, and thermoplastic and thermoset resins. Improvements in what were the economic five plastics, i.e. polyethylenes, polypropylenes, polyvinylchlorides, polystyrenes and polyesters, are constantly occurring. Use of metallocene catalysts is likely to produce plastics of a controlled chain length. 

Another current example of attitudes involves thermoplastic and thermosetting resins. The stringent tests referred to previously are invariably carried out on any thermoplastic which forms part of a primary pack. However, thermosets and in particular thermosetting lacquers, enamels and adhesives are rarely exposed to an extractive-type procedure, since they are not always recognised as plastics.

Electrical and physical properties of thermoplastic and thermoset resins... 

There are many thermoplastic and thermoset resins but only a few developed for use in manufacturing cables. Table 9.5 summarises the main properties of the more frequently used resins. 

Table 5 identifies the major parameters associated with basic processes used to fabricate thermoplastic and thermosetting resins. 

As technology advances, materials have been developed which evade the above classification. Mixtures of thermoplastics and thermosetting resins have been developed in which the thermoplastics material acts as a toughening agent for the thermosetting resin. Alloys or blends of two or more thermoplastics, or of plastics and rubbers, are becoming commonplace.

Looking at the different types of plastics and their applications large differences in the share of bio-based materials can be found. In 2010, the German Eederal Agency for Renewable Resources presented data for the German market in the year 2007, which was analysed in three different sectors thermoplastic and thermoset resins, elastomers, and man-made fibres (Figure 1.2). 

Although the data concerning these polymers are quite limited, both TCBP euid TCBS (as well as some of their appropriate derivatives) have been incorporated into thermoplastic and thermoset resin systems including polycarbonates (9,10,11), polysulfones (12), thermostable (aromatic) polyesters (13), alk polyesters ( ), unsaturated polyesters Tl5,16) and epoxy resins (16).

Kenaf originates mostly from Iraq, Tanzania, Jamaica, South Africa, Cuba and Togo. Kenaf fiber is extracted from bark of the kenaf tree. The fibers extracted both from the bast and the core of the bark (25). Some properties of kenaf fibers are shown in Table 3.3. Kenaf fibers can be used in both thermoplastic and thermoset resins for reinforcement.
