Hoses, automotive polymers

Synthetic and natural rubbers are amorphous polymers, typically with glass transition temperatures well below room temperature. Physical or chemical crosslinks limit chain translation and thus prevent viscous flow. The resulting products exhibit elastic behavior, which we exploit in such diverse applications as hoses, automotive tires, and bicycle suspension units. [Pg.36]

Principal uses include automotive V-belts, industrial and hydraulic hose, specialty roofing, heels and soles in footwear, wine coveting, and a wide variety of coated fabric uses, eg, rafts. Chloroprene elastomers are also used extensively in adhesives (qv). It is estimated that about 77,000 t of chloroprene are used each year in the United States. The two main suppHers of chloroprene elastomers in the United States are DuPont and Bayer. In addition, Distiguil (France) sells polymers through the A. Schulman Company. [Pg.233]

DuPont—Dow is the primary suppHer of these polymers. There is an estimated 18,000 t of these elastomers used per year. The main uses of CPE are in constmction, automotive, and electrical appHcations. These include power steering hose, electrical cords used in low voltage appHcations (extension cords, ignition wire), pond liners, and as a plastic modifier to improve impact modification. [Pg.233]

Enichem and DuPont ate two suppHers of acryHc elastomers. It is estimated there ate - 9000 t/yr of these elastomers used in the United States. The principal uses of acryHc elastomers ate in automotive appHcations requiring both oil and heat resistance. These include transmission, valve stem, crankshaft, pinion, and odpan gaskets and seals. In addition hose, tubing, toUs, and belts ate made from acryHc polymers. [Pg.233]

Though short fiber-reinforced mbber composites find application in hose, belt, tires, and automotives [57,98,133,164] recent attention has been focused on the suitability of such composites in high-performance applications. One of the most important recent applications of short fiber-mbber composite is as thermal insulators where the material will protect the metallic casing by undergoing a process called ablation, which is described in a broad sense as the sacrificial removal of material to protect stmcrnres subjected to high rates of heat transfer [190]. Fiber-reinforced polymer composites are potential ablative materials because of their high specific heat, low thermal conductivity, and ability of the fiber to retain the char formed during ablation [191-194].

TPEs find use in automotive, wire and cable, footwear, polymer modification, hose and tube, mechanical, bitumen modification, construction, adhesives and coatings, and film/sheet applications. [Pg.116]

As a result of its saturated polymer backbone, EPDM is more resistant to oxygen, ozone, UV and heat than the low-cost commodity polydiene rubbers, such as natural rubber (NR), polybutadiene rubber (BR) and styrene-butadiene rubber (SBR). Therefore, the main use of EPD(M) is in outdoor applications, such as automotive sealing systems, window seals and roof sheeting, and in under-the-hood applications, such as coolant hoses. The main drawback of EPDM is its poor resistance to swelling in apolar fluids such as oil, making it inferior to high-performance elastomers, such as fluoro, acrylate and silicone elastomers in that respect. Over the last decade thermoplastic vulcanisates, produced via dynamic vulcanisation of blends of polypropylene (PP) and EPDM, have been commercialised, combining thermoplastic processability with rubber elasticity [8, 9].

Applications of ethylene-propylene copolymers and terpolymers include automotive (the major use area), thermoplastic olefin elastomers, single-ply roofing, viscosity index improvers for lube oils, wire and cable insulation, hose, appliance parts, and polymer modification. [Pg.371]
