Polyester cloth-backed flat PP sheets (fleece-backed sheets) are normally used to manufacture large reservoirs for liquid containment purposes. Typically, such reservoirs are reinforced on the outside with fiberglass. The polyester mat backing serves as an adhesion key between the PP and the fiberglass resin. Fluorine surface activation can be used as a substitute for the fleece-backed material at a considerable cost-saving. Table 16.12 shows a comparison between the adhesive performance of the materials with two polyester resins. 

As an example, styrene polymerizes at ordinary temperatures and the rate of polymerization increases as temperature increases. The reaction is exothermic and becomes violent as it is accelerated by its own heat. Inhibitors are added to prevent the initiation of dangerous polymerization. When the styrene is used to fabricate materials, e.g., fiberglass resin, a catalyst may be added in the manufacturing process to initiate polymerization at a controlled rate. Any unbalance of these reactions in terms of quantities or temperatures could cause hazardous fire conditions. 

About one-half of the phthalic anhydride production is consumed for the preparation of plasticizers, mostly for the various flexible grades of poly(vinyl chloride). The remainder is roughly split between alkyd resin preparation used for many types of surface coatings, and for polyester resin composites with fiberglass reinforcement, the so-called fiberglass resins used in boats and other sporting equipment as well as for corrosion-resistant vessels and ducts used in chemical processing, some automotive parts, and as a convenient means of field repair of many of these items. 

OTHER COMMENTS used as a bleaching agent for flour, fats, oils, and waxes used as a catalyst for hardening of certain fiberglass resins useful in the treatment of acne and rosacea principally an initiator for vinyl chloride polymerizations also used as a curing agent for silicone rubbers an agent in the production of cheese.

Air sampling was not permitted, concentrations of styrene are unknown and contributions of other chemicals to this exposme cannot be excluded. However, exposmes to formaldehyde and phenol are unlikely as these workers did not lay-up fiberglass resin. Inhalation of sprayed styrene is the most attribution for the nemobehavioral impairments. The impairment exceeded that found in a review of boat building and other studies but tests were more sensitive and the styrene levels may have been higher. We encomage more neurobehavioral evaluations of styrene spraying workers using such sensitive tests. 

The section of warehouse involved in the fire contained a wide variety of materials ranging from pesticides such as paraquat and 245 T to fiberglassing resins and cylinders of sterethox, a mixture of ethylene oxide and CFCs. The calcium hypochlorite, which was not supposed...

Laminate MCMs (MCM-L) is shown in (Fig. 8.111). Essentially fine-line PCBs, MCM-Ls are usually constructed by first patterning copper conductors on fiberglass/resin-impregnated sheets as shown in Fig. 8.112. These sheets are laminated together under heat and pressure. Connections between conductors...
