Engineering plastics acrylonitrile butadiene styrene

Fig. 1. US total sales and captive use of selected thermoplastic resins by major market for 2001. Major market volumes are derived from plastic resins sales and captive use data as compiled by VERIS Consulting, LLC and reported by the American Plastics Council s Plastic Industry Producers Statistics Group. Selected thermoplastics are low-density polyethylene, linear low-density polyethylene, high-density polyethylene, polypropylene, nylon, polyvinyl chloride, thermoplastic polyester, engineering resins, acrylonitrile-butadiene-styrene, styrene-acrylonitrile, other styrenics, polystyrene, and styrene butadiene latexes.

In 1998, polyurethanes (PU) and engineering plastics were shown to make up some 58% of advanced materials used in sporting goods [2], and for the moulded sports products, polypropylene (PP) is used three times more, compared to the next most used plastic, acrylonitrile-butadiene-styrene (ABS) [1]. On the other hand, there are also trials for use of other plastics, even the use of tyre crumb for artificial surfaces, carpet underlays and playgrounds, although the use of the latter is not well developed yet (amounting to some 10% of the tyres crumbed). 

Acrylonitrile-butadiene-styrene (ABS). ABS materials have superior strength, stiffness and toughness properties to many plastics and so they are often considered in the category of engineering plastics. They compare favourably with nylon and acetal in many applications and are generally less expensive. However, they are susceptible to chemical attack by chlorinated solvents, esters, ketones, acids and alkalis. 

Acrylonitrile-butadiene-styrene (ABS) and acrylonitrile-styrene-acry- late (ASA) are rubber-toughened plastics based upon the styrene-acrylonitrile (SAN) copolymer matrix. The combination of the stiffness and toughness exhibited by these materials has made them increasingly attractive in engineering applications, and the activity of the patent literature testifies to a continuing interest in improving properties through modifications of structure. The aim of this paper is to discuss a quantitative approach to structure-property relationships in ABS and ASA polymers. 

Acrylonitrile-Butadiene-Styrene (ABS) Terpolymer. The acrylonitrile and styrene copolymer is grafted onto polybutadiene. The properties of SAN are combined with a greatly improved impact resistance and heat distortion resistance. ABS terpolymers And application as engineering plastics, in household appliances, luggage, telephone housings, automotive parts, and many more. 

As a measure of the level of sophistication of the industry the types of polymers consumed was as shown in figure 2. Others are mainly engineering thermoplastics (ETP), such as nylon, polyacrylates, polyacetals, polycarbonates, polyesters, and polpropylene oxide etc... These ETP s are growing at rates up to 20%. The main uses for plastic products are computer and business machine parts as well as design engineered products. The consumption of styrenic plastics (polystyrene acrylonitrile butadiene styrene - ABS) is high, relative to polyolefins, because of their demand in electric/electronic end-uses. 

Engineering plastic n. (1) A broad term covering those plastics, with or without fillers and reinforcements that have mechanical, chemical, electrical, and/or thermal properties suitable for industrial applications. R. B. Seymour, an outstanding authority, defined them as polymers thermoplastic or thermosetting, that maintain their dimensional stability and major mechanical properties in the temperature range 0-100° C. He listed the big five (among neat resins) as nylons, polycarbonate, acetals, polyphenylene ether, and thermoplastic polyesters. Among many others are acrylics, fluorocarbons, phenoxy, acrylonitrile-butadiene-styrene terpolymer, polyaryl... 

Plastics. Plastics denotes the matrix thermoplastic or thermoset materials in which additives are used to improve the performance of the total system. There are many different types of plastics that use large volumes of chemical additives including (in order of total additive consumption) polyvinyl chloride (PVC), the polyolefins [polyethylene (PE) and polypropylene (PP)], the styrenics —[polystyrene (PS) and acrylonitrile butadiene styrene (ABS)], and engineering resins such as polycarbonate and nylon. 

A recent paper by Meyer et indicates that it is the flame retardants that determine the recyclability of a polymer. Engineering plastics such as acrylonitrile-butadiene-styrene which contain PBDE are unsuitable for recycling because of the generation of PBDF and PBDD s. Moldings containing... 

Acrylonitrile-Butadiene-Styrene Copolymer/ PLA Blends Acrylonitrile-butadiene-styrene copolymer (ABS), an amorphous graft copolymer comprised of a rigid linear styrene-acrylonitrile copolymer (SAN) grafted to rubbery butadiene, has been used to toughen engineering plastics [25, 57]. To improve compatibility of the immiscible ABS/PLLA blends, and improve their mechanical properties,... 

Acrylonitrile-butadiene-styrene terpolymer is one of the engineering plastics most frequently used as outer casings for computer equipment such as monitors, keyboards, and other similar components [98].
