Acrylonitrile–Butadiene–Styrene (ABS) Polymers

Abstract

Acrylonitrile–butadiene–styrene (ABS) polymers are composed of elastomer dispersed as a grafted particulate phase in a thermoplastic matrix of styrene and acrylonitrile copolymer (SAN). The presence of SAN grafted onto the elastomeric component, usually polybutadiene or a butadiene copolymer, compatabilizes the rubber with the SAN component. Property advantages provided by this graft terpolymer include excellent toughness, good dimensional stability, good processibility, and chemical resistance. The system is structurally complex. This allows considerable versatility in the tailoring of properties to meet specific product requirements. Consequently, research and development in ABS systems is active. Numerous grades of ABS are available, including new alloys and specialty grades for high heat, flaming‐retardant, or static dissipative product requirements. Good chemical resistance combined with the relatively low water absorptivity \documentclass{article}\usepackage{amssymb}\pagestyle{empty}\begin{document}${(<1\%)}$\end{document} results in high resistance to staining agents. Antioxidants substantially improve oxidative stability. Applications involving extended outdoor exposure require the use of stabilizing additives, pigments, and protective coatings. In manufacturing, grafting is achieved by the free‐radical copolymerization of styrene and acrylonitrile monomers. The commercial processes for manufacturing ABS are discussed. ABS is sold as an unpigmented product for on‐line coloring using color concentrates during molding, or as precolored pellets. ABS can be processed by compression and injection molding, extrusion, calendering, and blow‐molding. Post‐processing operations include cold forming, painting, and adhesive bonding. As a “bridge” polymer between commodity plastics and higher performance engineering thermoplastics, ABS has become the largest selling engineering thermoplastic.

Mechanical, thermo-mechanical and morphological characterization of ABS based composites loaded with perlite mineral

“…The advanced mechanical properties and easy processing characteristics are the reasons for usage of ABS as an engineering plastic. The most utilizations of ABS copolymer across a range of numerous products including toys, musical instruments, automotive components, protective helmets, telephone switchboard panels, sporting goods and medical devices [4,5]. Due to the increase in its usage for 3D printing technology, the ABS became popular in recent years.…”

The effects of fiber silane modification on the mechanical performance of chopped basalt fiber/ABS composites

“…Hence, different phase polarities are observed in ABS due to its complex structure. 4,5 In the literature, various short inorganic fibers including basalt fiber (BF) 6,7 and glass fiber 1,2,[8][9][10][11][12][13][14][15][16][17][18] are used in ABS matrix to improve the mechanical properties.…”

“…MSOE supplied the two types of 3D-printer filament: acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA). ABS is an extremely versatile plastic whose properties can be easily altered by synthesizing it with varying amounts of its three monomers: acrylonitrile, butadiene, and styrene (Chang) (Kulich 2001(Kulich , 2003. As a terpolymer-a copolymer possessing three monomers-ABS inherits a wide variety of properties from its substituents, such as, toughness at reduced temperatures from polybutadiene, strength from the intermolecular hydrogen bonding with the nitrile groups, and homogeneity from the styrene.…”
