Among the many solvents for plastics, the most widely used are toluene, tetrahydrofuran, dimethylformamide, diethyl ether, acetone, and formic acid. In certain cases, chloroethylene, ethyl acetate, ethanol, and water are also useful. It should he noted that the flammability and toxicity of many solvents requires special care In handling. Benzene should be avoided as much as possible. Tables 3.1 and 3.2 show a compilation of the behaviors of the most important plastics in various solvents. For the systematic analysis of plastics, the distinction between soluble and insoluble polymers provides the first separation into two groups. One can then apply chemical methods to investigate these two groups further. 

An effective solvent for plastics objects may be required as a component of an adhesion or repair treatment where the edges to be joined require etching or softening. By contrast, a poorly effective solvent for plastic may be sought as a component of a cleaning treatment where the soil is dissolved while the original plastic surface remains undamaged. In addition, selection of an effective and appropriate solvent may also depend on its evaporation rate, environmental or health and safety considerations. 

Ethyl cyanoacrylate is a little less polar than methyl cyanoacrylate, and has the ability to wet plastic surfaces more readily, and is a better solvent for plastics. With this added ability to make intimate contact with the surface, the bonds on plastic are stronger with ethyl cyanoacrylate than with the methyl ester. This difference in performance gives rise to the adage that methyl is for metal and ethyl is for everything else. Sometimes this difference can be utilized in reverse to good advantage to avoid stress cracking on such sensitive plastics as polycarbonate and polyacrylate.

Non-irritant solid materials or powders may be tested with a drop of water in a test chamber. Organic solvent vehicles, e.g., acetone, ethanol or methyl ethyl ketone, may be used instead of water, depending on the material or powder to be tested. The use of water or organic solvent improves the extraction of chemicals and their penetration into the skin. Moisturizing also helps the application of a test chamber containing powder or solid material. Water is recommended for textiles and paper, but organic solvents for plastic or rubber materials (Niklasson 1995). 

Aromatic Hydrocarbon n (1) A compound of carbon and hydrogen whose molecular structure contains one or more rings of six carbon atoms, with at least one of the rings containing alternating, resonant single and double bonds. Benzene, which is the simplest of the aromatic hydrocarbons, has the molecular formula CeHe. The family includes many solvents for plastics. 

In the second edition of this Handbook, Miron and Skeist stressed the importance of the solubility parameter in formulating adhesives for plastics. The concept of solubility parameter has been discussed in Chapter 1. Table 1 gives the solubility parameter for many plastics. Table 2 gives the solubility parameters of many solvents for plastics, along with their fractional polarities.
