Clothing elastomer

The milled stock (111 parts) was dispersed in CH2C12 and a solution of f-butylphenolic resin (40 parts) in CH2C12 was stirred in. Additional CH2C12 was added so that the final slurry had 20% solids. The solvent was then evaporated and a thin film was produced. This film was pressed against the prepared substrate and covered with a sheet of finely-woven cotton cloth. The final sandwich was first pressed in a mold for 30 min at room temperature and 25,000 lb on a 5 in. ram and then cured for 40 min at 150°C and 30,000 lb on a 5 in. ram. The thickness of the elastomer layer in the resulting cloth-elastomer-substrate sandwich was 0.4 mm. Peeling experiments were carried out on strips of cloth-backed elastomer layer after trimming them to a uniform width on the substrate of 2 cm. [Pg.579]

Rubber and Synthetic Elastomers. For many years nondecorative coated fabrics consisted of natural mbber on cotton cloth. Natural mbber is possibly the best all-purpose mbber but some characteristics, such as poor resistance to oxygen and ozone attack, reversion and poor weathering, and low oil and heat resistance, limit its use to special appHcation areas (see Elastomers, synthetic Rubber, natural). [Pg.296]

This comprises composite materials on mica, glass fibre and asbestos bases, impregnated or glued together with silicone resins or silicone elastomer. These materials must not contain any organic fibrous materials such as paper or cloth backing, which is covered under class B and even F insulation systems. [Pg.221]

Because of its excellent range of properties and reliability, poly(fluoroalkoxyphosphazene) elastomers are used as seals, gaskets, and shock mounts in demanding military, aerospace, petroleum and industrial applications. In addition, applications under development for this elastomer include fuel hoses for artlc use, coated fabrics for protective clothing, sealants, coatings and medical devices. [Pg.279]

The pigment also lends itself to application in elastomers, such as natural rubber blends. It is migration fast enough to satisfy most specifications. P.R.53 1 is also completely bleed resistant in natural rubber, although some color is transferred into the wet cotton cloth liner, the wrapper (Sec. 1.8.3.6). P.R.53 1 is lightfast enough for most applications. Products containing P.R.53 1 are not always entirely fast to hot water or alcohol. [Pg.321]

Do you think that daily life would have been easier and colourful without the discovery and varied applications of polymers The use of polymers in the manufacture of plastic buckets, cups and saucers, children s toys, packaging bags, synthetic clothing materials, automobile tyres, gears and seals, electrical Insulating materials and machine parts has completely revolutionised the daily life as well as the industrial scenario. Indeed, the polymers are the backbone of four major Industries viz. plastics, elastomers, fibres and paints and varnishes. [Pg.134]

Kevlar fibers are available in four forms Kevlar, Kevlar 29, Kevlar 49 and the recently developed Kevlar 149. Kevlar is designed specifically for reinforcements of elastomers (e.g. tires and belts), while Kevlar 29 is used primarily for tensile members sueh as ropes, cables, webbings and ballistic cloth. Kevlar 49 and 149 are designed for reinforcement of high performance PMCs. Kevlar 149 offers a 40%... [Pg.196]

If we disregard metals and some inorganic compounds, practically everything else in this world is polymeric. Polymers form the basis for life itself and for our communications, transportation, buildings, food, etc. Polymers include protein and nucleic acids in our bodies, the fibers (natural and synthetic) we use for clothing, protein and starch we eat, elastomers in our automotive tires, paint, plastic wall and floor coverings, foam insulation, dishes, furniture, pipes, etc. [Pg.754]

Organic polymers are manufactured and used on a massive scale as plastics and elastomers, films and fibres in areas as diverse as clothing, car tyres, compact discs, packaging materials, prostheses and most recently electroluminescent and electronic devices and sensors. The enormous growth in the use of organic polymeric materials since the 1930s can be mainly attributed to their ease of preparation, lightweight nature and unique ease of fabrication. [Pg.97]

ACRN is used to make acrylic fibers, acrylonitrile-butadiene-styrene (ABS), and styrene-acrylonitrile (SAN). Worldwide acrylic fiber accounts for over half of total demand while ABS and SAN consume about 30% of output. Smaller applications include nitrile rubber copolymers (4%), adiponitrile (ADN) and acrylamide. Acrylic fibers are used in carpets and clothing while ABS and SAN resins are used in pipes and fittings, automobiles, furniture, and packaging276. In the United States the ACRN uses are distributed differently 38% is used in ADN, 22% in ABS and SAN, 17% in acrylic fibers, 11% in acrylamide, 3% in nitrile elastomers, and 9% in miscellaneous, which includes polymers, polyols, barrier resins and carbon fibers277. [Pg.394]

Polyurethane Methanol 1. Abrasion followed by brushing. Grit or vapor blast or 280-grit emery cloth followed by solvent wipe. 2. Incorporation of a chlorosilane into the adhesive elastomer system 1% by weight is usually sufficient. Chlorosilane is available commercially. Addition to adhesive eliminates need for priming and improves adhesion to glass and metals. Silane may be used as a surface primer... [Pg.508]

The cloth-backed elastomer layer was peeled off a short distance, bent back through 180°, and then stripped off at 1 cm/min. The peel force P per unit width of the detaching layer was calculated from the time-average force observed (10). [Pg.580]
