Automotive seats

The product is a hquid recommended for flame retarding flexible urethane foams in furniture or automotive seating. It also appears to be useful in polystyrene foam, textile backcoating, and polyester resins. 

The alloys can be processed into parts requiring hydrolytic and autoclave stabiHty, such as desalinization filter frames and medical devices. Foamed products are used in cabinets for business machines, computers, and copiers. Automotive seat backs are made by blow mol ding and replacements for metal parts by injection mol ding. 

One of the more advertized advances in commercial offering of polyurethanes from renewable resources was the introduction of soy-based polyol in the 2008 Ford Mustang [180, 181]. Ford partnered with Lear Corp. to produce automotive seats containing up to 40% soy-based polyol. This was hailed as a throw-back to the early days of Ford Motor Company, when Henry Ford incorporated as much as 60 pounds of soybeans into paint components and molded body parts for the Model T. 

The poly(vinylidene chloride-cu-vinylchloride) may be injection molded and extruded. Extruded pipe and molded fittings which were produced in large quantity in the 1940s have been replaced to some extent by less expensive thermoplastics. A llal extruded filament is used for scouring pads and continuous extruded circular filament is used for the production of insect screening, filter clothes, fishing nets and automotive seat covers. 

Domestic woolly sheep are bred for wool and meat in large quantities in Australia, New Zealand, and other agricultural countries. The skins are byproducts, and their conversion into high-quality fur or leather can be regarded as beneficial waste management. Lambskins and sheepskins have grown markedly more popular in recent years for clothing, automotive seat covers, medical, and other applications. Woolly sheepskins account for about half of total fur production and are processed on an industrial basis. 

Molded flexible urethane foams have been used for producing intricate foam products, such as automotive seats and furniture cushions. Molded foams are composed of high-density foam skin and low-density foam core. An example of density distribution of a 10-cm thick molded mattress foam is shown in Figure 9. 

In automotive applications, e.g., automotive seats, molded HR foam is the major process used. HR foam is produced by using four kinds of technologies (a) crosslinker technology, b) graft-polyol technology, (c) PHD polyol technology, and (d) specialty isocyanate technology. 

Dual-Hardness Molded Foam A number of formulations for molded foams have been reported. A new development in recent years is dual-hardness molded foams. Automotive seats and furniture have been labor-intensive products. These products provide good comfort by using different layers of different hardnesses. Molded foams produced by using a single formulation have relatively comfortable cushioning properties in terms of sag factor. However, this advantage is not enough to satisfy customers requirements for comfort. 

The first significant use of a urethane in the automotive industry was the 1957 model year with the use of cut urethane flexible foam topper pads for automotive seating in several cars. These topper pads replaced non-woven cotton padding. 

As a model system, a conventional flexible urethane foam formulation developed by Union Carbide for automotive seat applications has been used. It consists of ... 

These generalities will be illustrated through a discussion of the release agent technology in two different and important types of molded urethane product. These are automotive seat foams and RIM urethanes. Before that discussion, however, it seems useful to discuss why Options 1, 2, and 3 for releasing urethanes have not been successful so far. 

The creation of the autocatalytic high MW aminic polyols based on N-methyl substituted poly amines, represents an important development in the area of poly ether polyols for low-fogging flexible PU foams. The VORANOL VORACTIV polyols developed by DOW represent a revolutionary group of autocatalytic polyols with reduced volatile organic compounds (VOC) emissions in PU products, especially in high resilience foams for bedding and automotive seating [149, 150]. 

The major interest in flexible polyurethane foams is for cushions and other upholstery materials. Principal market outlets include furniture cushioning, carpet underlay, bedding, automotive seating, crash pads for automobiles, and packaging. The density range of flexible foams is usually 1-6 Ib/ft. (0.016-0.096 g/cm ). The foam is made in continuous loaves several feet in width and height and then sliced into slabs of desired thickness. 

Automotive seat back substrates are among large bow-molded parts made from very-low-melt-flow, high-melt-strength PP. Automotive is a major polypropylene market. The ease of recycling of PP is an important consideration in automotive applications.

Cannon has developed complete systems for the manufacture of moulded polyurethane automotive seating elements made with varying combinations of several raw materials. The resultant cushions - although produced in a random sequence on the same moulding line - are characterised by mechanical properties tailored to the specific application of each part [1].

Developed in the early 1980s as a revolutionary tool for the production of foamed refrigerator doors, the well-known concept of the rotary polymerisation system is now being proposed as a compact and simple mould-carrying system for the production of automotive seats (see Figure 3.12).
