Isometric data from the creep curves may also be superimposed on the creep rupture data in order to give an indication of the magnitudes of the strains involved. Most plastics behave in a ductile manner under the action of a steady load. The most notable exceptions are polystyrene, injection moulding grade acrylic and glass-filled nylon. However, even those materials which are ductile at short times tend to become embrittled at long times. This can cause... 

In general, plastics are superior to elastomers in radiation resistance but are inferior to metals and ceramics. The materials that will respond satisfactorily in the range of 1010 and 1011 erg per gram are glass and asbestos-filled phenolics, certain epoxies, polyurethane, polystyrene, mineral-filled polyesters, silicone, and furane. The next group of plastics in order of radiation resistance includes polyethylene, melamine, urea formaldehyde, unfilled phenolic, and silicone resins. Those materials that have poor radiation resistance include methyl methacrylate, unfilled polyesters, cellulosics, polyamides, and fluorocarbons. 

Responding to the need for thinner, smaller components in the electronics industry, Ferro Corp had developed an advanced brominated polystyrene flame retardant under their Pyro-chek name for high temperature glass-filled engineering polymers. Pyro-Chek 68Pbi is said to offer improved thermal stability and colour for high temperature applications. 

Around 8% bromine content in the final PBT compound is sufficient to achieve the V-0 test rating for all types of brominated flame retardants, but some affect the physical and mechanical properties of the resultant materials more than others. Polymeric brominated styrene additives would be preferred in glass-filled compounds. Brominated polystyrene, such as Saytex HP-7010 from Albemarle Corp. and poly(dibromostyrene) are such materials. They retain excellent properties after heat ageing. High impact strengfti and excellent electrical properties are especially noted for HP-7010 due to the additive s high purity and low aliphatic halogen content. 

Both of these equipment are mechanically more complex than stereolithography and most of other technologies. A variety of thermoplastic materials such as nylon, glass filled nylon, and polystyrene are available. Surface finishes and accuracy are not quite as good as with stereolithography, but material properties can be quite close to those of the intrinsic materials. The method has also been extended to provide direct fabrication of metal and ceramic objects and tools.

From this analysis we can see that the determining factor in the design is the maximum stress level that will permit a creep in the range of 5%. Based on this factor, it is apparent that the material to be used, if minimum thickness is the criterion, is the glass-filled polystyrene. From an economic standpoint this is also the best material since the thickness is 20% of the polystyrene and 15% of the polypropylene while the relative cost of the glass-filled material is about 2.5 times that of the polystyrene or polypropylene and the molding costs would be comparable for the three materials.

Resin content in glass-filled polystyrene materials was analyzed without sample preparation. Analysis can be performed at line to control compounding and blending at the molding machine.

Compound density in products can vary locally due to uneven distribution of fillers. For example, in one study on glass-filled polystyrene in an injection molding process, the density varied between 0.9 and 1.4 g/cm, depending on sampling location and process condition in an injection molded bar [ 1 ].
