Reinforcement. PVA fiber in the form of short cut chips having a length of several millimeters to several tens of millimeters is widely used as raw material for paper and for reinforcing plastics, cement, and the like, and has been acquiring more and more significance. 

Plastic cements are hydrauHc cements that have plastici2ing agents added to Pordand cement during the grinding operation to make them dow better. The primary use for plastic cements is in plasters and stucco. 

The main uses of toluene are as a solvent in paints, rubber, and plastic cements and as a feedstock in the manufacture of organic chemicals, explosives, detergents, and polyurethane foams. Xylenes (which exist as three isomers) are used in the manufacture of DMT, alkyd resins, and plasticizers. Naphthalene is mainly used in the manufacture of dyes, pharmaceuticals, insect repellents, and phthalic anhydride (used in the manufacture of alkyd resins, plasticizers, and polyester).

Thermosets A number of thermosets have been used as adhesives. Phenolic resins were used as adhesives by Leo Baekeland in the early 1900s. Phenolic resins are still used to bind together thin sheets of wood to make plywood. Urea resins have been used since 1930 as binders for wood chips in the manufacture of particle board. Unsaturated polyester resins are used for body repair and PUs are used to bond polyester cord to rubber in tires, and vinyl film to particle board, and to function as industrial sealants. Epoxy resins are used in the construction of automobiles and aircraft and as a component of plastic cement. 

Kaolin clays are naturally occuring sedimentary deposits composed largely of kaolinite mineral. Typical impurities in these deposits are iron oxides, titanifer-ous minerals, silica, feldspar, mica, sulfides and organic matter. The majority of kaolin clay produced in the world is used in the paper industry as coating and filler materials. This mineral also makes an excellent filler, carrier, opacifier and diluent in a variety of industrial products such as paints, plastics, cement, rubber, pharmaceuticals, etc. 

Unsaturated polyester resins have replaced lead for auto body repair, and polyurethanes (PUs) are being used to bond polyester cord to rubber in tires, to bond vinyl film to particleboard, and as industrial sealants. Epoxy resins are used in automotive and aircraft construction and as a component of plastic cements. 

Reactivity with Common Materials — This is limited to hazardous reactions with fuels and with common materials of construction such as metal, wood, plastics, cement, and glass. The nature of the hazard, such as severe corrosion or formation of a flammable gas, is described for specific chemicals in Chapter 4. 

The October 1996 issue of the Dutch magazine Natuur Techniek makes mention of a research of the University of Bristol, Great Britain into the effects of implanting artificial hip joints and knees into the body. This research showed that metal particles and pieces of plastic, cement and polymers are gradually released from the artificial joints. Such particles were found in the neighbourhood of joints and lymph nodes. However, they were also present in the bone marrow, the spleen and the liver. The more artificial limbs are exposed to loads, the more particles will be released. So far there are no indications of health hazards, but it is not possible to predict long term effects. 

The most common design is the bead type, which is usually glass-coated. However, thermistors can also be made into washes, disks, or rods. They can also be encapsulated in plastic, cemented, soldered in bolts, encased in glass... 

Uses n-Butyl alcohol is used extensively in a number of industries. For instance, it is used as a solvent in industries associated with the manufacture of paints, varnishes, synthetic resins, gums, pharmaceuticals, vegetable oils, dyes, and alkaloids. n-Butyl alcohol also finds use in the manufacture of artificial leather, rubber, and plastic cements, shellac, raincoats, perfumes, and photographic films. 

Shaping additives may act as lubricants, plasticizers, cements, porosity promoters (porogenic additives), etc. [9]. The powdered starting material mixed with the additives may be dry, or converted to a plastic pulp by the addition of a suitable liquid. One sometimes distinguishes ... 

Is the tradename for wollastonite. It is available in three grades varying in particle size. An acicular calcium silicate, it is used as a filler and reinforcing agent in plastics, cement, wallboard, soil conditioner and in casting plasters.

Toluene, a colorless liquid by itself, is the active ingredient in almost all types of plastic cement. According to the Toxic Hazard Rating Code, a guide to industrial chemicals and potential hazards, toluene is dangerous, but is not the immediate-brain damage chemical that we have been lead to believe it is. 

Turning the test well into a commercial well involves running a casing in and cementing it in place. Inside the casing is a smaller diameter tube, open at the bottom for the oil. Other methods include a gravel pack to prevent collapse of the walls or the use a plastic cement in sand.

Epoxides are formed by oxidation of ole-finic or aromatic double bond. The oxidizing agents for such epoxidation reactions are peracids or peroxides with or without catalysts. The epoxy compounds are widely used as intermediates to produce synthetic resins, plasticizers, cements, adhesives, and other materials. 

Hopefully, the information in this book will help hasten the adoption of plastic cements and assure the construction engineer of the merits of the widely used sealants and caulking compositions. 

Caulking- (1) A flexible material used to seal a gap between two surfaces e.g. between pieces of siding or the comers in tub walls. (2) To fill a joint with mastic or asphalt plastic cement to prevent leaks. 

Plastic Solvent n.o.s. A name commonly used for mixtures of liquids employed for dissolving plastics or for thinning plastic cements. In general, they may contain flammable liquids, such as acetone, amyl acetate, or some of the alcohols or ketones. The classification is determined by the flash point. ICAO A2...
