Automobile industry polypropylene

There is a demand for more powerful polymers like for example PEEK [103, 107, 111], which enables new application areas in the automobile industry and medical fields, as shown in Fig. 81 and underlines the increasing potential of SLS-technologies. Because of this EOS GmbH recently presented a high temperature system, EOSINT P 800, along with PEEK HP3 for SLS. There is a further interest in qualification of bulk polymers like polypropylene [100]. 3D Systems Inc. recently presented DuraForm PP 100 for SLS. Further more there is an interest in some technical polymers like Polyoxymethylene [112]. [Pg.275]

Polypropylene, a homopolymer polyolefin engineering plastic provides excellent chemical resistance, purity and it is the lightest of all commercial plastics. PP offers innovative solutions to many challenges that face the automotive industry today. Its low density compared to traditional materials significantly contributes to fuel economy and reduced material costs. Its excellent noise, vibration, and harshness (NVH) properties contribute to enhanced passenger comfort. Thus, PP has become the most important thermoplastic material in automobile industry. PP homopolymers, random copolymers, and impact copolymers are used in products such as automotive parts and battery cases, carpeting, electrical insulation, and fabrics. [Pg.269]

While cellulose fiber reinforced polypropylene (PP) is already used by default for example in the automobile industry for interior parts (Karas and Kaup, 2005), the conventional use of cellulose fiber reinforced PLA is still at the beginning. But there are also some products such as biodegradable urns, mobile phone shells or prototypes of spare tyre covers made from natural fiber reinforced PLA at the market (Anonymous, 2007 Iji, 2008 Grashom, 2007). Maty studies deal with the use of natural fibers as reinforcements in PLA composites. An overview about the mechanical characteristics and apphcation areas of natural fiber-reinforced PLA can be foimd for example in Bhardwaj and Mohanty (2007), Avella et al. (2009), Ganster and Fink (2006), Jo-noobi et al. (2010), and Graupner et al. (2009). For the improvement of the composite characteristics it is still necessary to carry out optimization processes for fibers, PLA matrix and the interactions of both. Moreover the processing parameters, force elongation characteristics of fibers and matrix as well as the use of additives like plasticizers or adhesion promoters have decisive influences on the mechanical characteristics of the composites. [Pg.182]

A major advantage is polypropylene s higher temperature resistance, which makes PP particularly suitable for items such as trays, funnels, pails, bottles, carboys and instrument jars that have to be sterilized frequently for use in a clinical environment. Polypropylene is a translucent material with excellent mechanical properties. PP has a wide range of applications such as packaging, fibers, automobile industry, nondurable goods and in building construction. [Pg.33]

Plate-shaped GMT is a glass mat reinforced, flat, semifinished thermoplastic, which is mostly based on polypropylene that is processed using compression processes. The glass content depends on the requirements and is between 20 and 40 weight %. GMT components show a high impact resistance and stiffness with comparatively low weight. Molded parts made out of GMT are mostly used in the automobile industry for trim and carrier components in nonvisible areas. [Pg.101]

Mica provides similar benefits in a wide range of thermoplastic and thermoset composites including polyolefins, polyamides and styrenics. It is also reported that surface coated mica further increases tensile strength, flexural strength and modulus, and heat deflection temperature. The automobile industry is the main user of mica-filled composites, either with polypropylene or nylon as polymer matrix. Up to 40% mica loadings are used, sometimes in association with calcium carbonate, to produce various injection... [Pg.298]

In 75% of the cases, wood fibres are the preferred filler for thermoplastic matrices. Their high availability may account for this. The resulting composite material is internationally known as WPC, which stands for wood plastic composite. They have been produced industrially since 1980 and the market has gradually increased in the last 10 years, especially in the United States, reaching 700 000 metric tons with an 11% increase rate per annum. In Europe, the WPC market is considered to be emerging. At the best estimations, it reached only 100 000 metric tons in 2005 (Anonymous, 2006) and in lapan the market is even smaller. In America, more than 50% of the WPC is used for parquets and decking made with polyethylene. In Europe, it is the automobile sector that is preponderant with polypropylene-based composites. [Pg.133]

Nowadays, various kinds of plastic products are used in our daily lives. In detail, polyolefins, represented by polyethylene and polypropylene, are modem indispensable materials because of their superb properties, namely, they are lightweight, inexpensive, possess good processability, chemical stability, high mechanical strength, etc. Therefore, their applications range over industrial materials, household products, and automobile parts to name just a few areas. The worldwide production of PE and PP went beyond 100,000,000 ton ear in 2005 and it is still increasing. [Pg.373]

Nanoclay/polypropylene composites are being used as functional parts in automobiles and only a single company. General Motors, is using about 660,000 lbs of nanocomposite material per year [2], This is a clear indication of the technological impact of the use of nanocomposites in industrial applications. [Pg.516]

Industrial applications of polyolefin fibers include woven and nonwoven geotextiles, agriculatural fabrics, construction sheeting, automobile fabrics, filtration media, rope/twine, woven bags, narrow-woven web and tapes, tents, and tarpaulins. Geosynthetic fabrics will continue to be a growing market for polypropylene nonwovens. [Pg.5336]

Plastics in MSW The Americas, in the United States, plastic resin sales and captive use reached 46.2 million tons in 2001, a 4% decrease from 2000, according to the American Plastics Council (1). Resin production rose to 45.9 milUon tons in 2001, up 4.8% from the previous year. The U.S. plastics industry continues to expand into new markets as plastic products come to replace ones made of wood and metal (Fig. 1). In the United States, some 232 million tons of MSW were generated in 2000, an increase of 0.9 million tons over 1999 (Fig. 2). Of this stream, plastics constitute about 10.7 wt%. Plastic containers and packaging dominate, followed by materials in goods such as automobiles, appliances, electronics, furniture, and carpeting. Plastic resins used in containers and packaging include poly(ethylene terephthalate) (PET in soft drink bottles with polypropylene [PP] caps), high density polyethylene (HDPE in milk and water bottles), poly(vinyl... [Pg.7009]

Melt blending of polymers is a widely used technique for tailor-making polymeric materials to generate the desired properties. Blending polypropylene block copolymer (PPBC) with elastomeric ethylene-propylene-diene terpolymer (EPDM) produces a range of useful materials commercialized in early 1970 s that found significant uses in the automotive industry. Polyolefin-based bumpers dominate the automobile market in Europe and Japan and have made in-roads in the North American market. In India, the polyolefin blend for car bumpers was commercialized in 1992. [Pg.94]

Polypropylene is a versatile plastic with applications ranging from packaging to automobile and textile industry. It possesses properties similar to those of PE and hence, competes with PE in several product applications. It is generally used in packaging applications as an alternative to PE. Due to its higher stability, PE is generally preferred over PP in applications where the product is to be used in an oxidative enviromnent. However, the oxidative stability of PP can be improved through addition of antioxidants. Textile industry is another major area of application for PP where it is primarily used to produce synthetic fibers (Maier and Calafut, 1998 Miller, 2009). [Pg.20]

Among polyolefins, polypropylene has recently become an attractive candidate for many engineering applications. New polymerization processes introduced in the last decade make polypropylene one of the most favorable matrices for high-volume composites and blends. Relatively low priced, excellent chemical resistance, good processibility and the possibility to modify, it is spreading into automotive, land transport, home appliances and other industries. The mass application of PP in automobiles, mass transport vehicles, household appliances and the construction industry requires stiffness and fracture toughness similar to those of engineering plastics (ABS,... [Pg.190]

It is remarkable, that not only flexible substrates such as films or fabrics but also large stiff objects (e.g., fenders for automobiles) that are made from polypropylene (PP) or ethylene-propylene-diene-terpolymer EPDM) are plasma-treated on an industrial scale. It should be noted that a large proportion of these applications involve surface modifications for improved adhesion, and that such processes are commonly accomplished with the aid of air or oxygen plasmas [59,123,124]. [Pg.58]

Talc has been the second mineral of choice to fill polypropylene. Such applications have usually been automotive and industrial. Talc is a general purpose filler mineral and is highly compatible with polyolefins. It is widely used to increase stiffness and heat resistance in polypropylene automobile trim parts that do not require high reinforcement. [Pg.376]
