Into this mixture of aluminum, copper tubes are inserted, which later enable the temperature control of the synthetic resin molds. An upper top layer generates a straight plane and a clean upper surface of the mold (Figure 1.286 (e)).

Formaldehyde has hundreds of uses. Its largest use is in the production of synthetic resins. Many formaldehyde resins are hard plastics used in molding and laminates. Formaldehyde resins are used to treat textiles to make them wrinkle-free. It is also used to produce adhesives, which are used extensively in the production of plywood and particleboard. Other common uses are as disinfectants, fungicides, and preservatives. Formalin has been the traditional embalming fluid used in the mortuary industry for the last century. Formaldehyde is also used in papermaking, textile production, and fertilizers.

Coconut shell is the source of two other products, coconut shell flour and activated charcoal. Powdered coconut shell is used in the plastics industry as a compound filler for synthetic resin glues. It is also used as a filler and extender of phenolic molding powders that give a smooth and lustrous finish to molded articles, thereby improving their resistance to moisture and heat. Activated charcoal is an adsorbent for toxic agents. It has been used in gas masks, but can also be used to remove odors and industrial stench. As well, this by-product is a contact catalyst used to facilitate some industrial chemical reactions (61).

An invention was based on the discovery that many volatile odiferous substances are capable of forming inclusion compounds with CD, which are well suited to incorporating in synthetic resins prior to heat processing to form products such as films, fibers, moldings, etc (Shibanai et al., 1982). 

Notable among the thermoplastic materials are polyethylene, polypropylene, polyvinyl chloride, the styrene synthetic rubber blends, the acrylics, and the fluorocarbons. Notable among the thermosetting reinforced materials are the polyesters, epoxy, and the furan resins as custom-made reinforced materials, and the phenolic and epoxy resins molded, filament-wound, and/or extruded with reinforcement. AU these materials are available as piping, sheet stock, and miscellaneous molded and fabricated items. These materials, particularly polyvinyl chloride, polypropylene, and reinforced polyesters, are now being used extensively for ventilating ductwork in handling corrosive fumes. They have proved to be economically improved over metals such as stainless steel, lead.
