What You'll Learn
ABS is a thermoplastic polymer
Acrylonitrile Butadiene Styrene (ABS) is a thermoplastic polymer. It is a copolymer, made by combining three monomers: acrylonitrile, butadiene, and styrene. ABS is a versatile plastic with a wide range of applications, from computer keyboards and toys to automotive parts and construction materials.
ABS is a popular choice for many industries due to its low production cost, ease of machining, and desirable physical attributes. It is strong, tough, and heat-resistant, with good electrical insulation properties. ABS has a low melting point, which makes it suitable for injection moulding and 3D printing. It can be easily moulded, sanded, and shaped, and its glossy surface finish is compatible with a wide range of paints and glues.
The different monomers in ABS each contribute specific properties to the final product. Acrylonitrile provides chemical and thermal stability, hardness, and rigidity. Butadiene adds toughness, strength, and impact resistance. Styrene gives the plastic its glossy finish, as well as hardness and rigidity. The proportions of each monomer can be varied to create different types of ABS plastic with specific characteristics.
ABS is commonly used in combination with other materials through a process called co-extrusion. This allows for the creation of new properties and enhances the versatility of the plastic. For example, combining ABS with PMMA improves its UV resistance.
ABS has some disadvantages, including poor solvent and fatigue resistance, and susceptibility to UV exposure and weathering. Its low melting point makes it unsuitable for high-temperature applications. However, overall, ABS is a highly useful and versatile thermoplastic polymer with a wide range of applications.

It is made from acrylonitrile, butadiene and styrene
Acrylonitrile Butadiene Styrene (ABS) is a common thermoplastic polymer that is widely used across various industries. It is made from the polymerization of three monomers: acrylonitrile, butadiene, and styrene. The proportions of these monomers can vary, typically ranging from 15-35% acrylonitrile, 5-30% butadiene, and 40-60% styrene.
Acrylonitrile is a synthetic monomer produced from propylene and ammonia, and it provides ABS with chemical and thermal stability. It also contributes to the plastic's hardness, rigidity, and heat deflection temperature. Butadiene, on the other hand, is a petroleum hydrocarbon obtained from the C4 fraction of steam cracking. Butadiene particles impart elasticity and impact resistance to ABS. Styrene is made through the dehydrogenation of ethylbenzene and gives the plastic a glossy, impervious surface, as well as hardness and improved processability.
The combination of these three monomers results in a tough, durable, and versatile plastic with superior properties compared to pure polystyrene. ABS is known for its high impact resistance, toughness, and rigidity. It has excellent stability under load and can withstand heavy use and adverse environmental conditions. Additionally, ABS has good electrical properties and low heat and electricity conductivity, making it suitable for electrical insulation protection.
The versatility of ABS extends to its range of colour and surface texture options. It can be manufactured with a high-quality finish and is easily moulded, sanded, and shaped. These characteristics, along with its reasonable production costs, make ABS a popular choice for many applications, including computer keyboards, LEGO bricks, automotive components, protective headgear, and musical instruments.
However, ABS does have some limitations. Its low melting point makes it unsuitable for high-temperature applications, and it has poor solvent and fatigue resistance. Additionally, ABS must be adequately protected from UV rays and exposure to extreme weather conditions to prolong its life outdoors. Despite these shortcomings, ABS remains a valuable and widely used plastic due to its unique properties and ease of manufacturing.

It is used in 3D printing and injection moulding
Acrylonitrile Butadiene Styrene (ABS) is a common thermoplastic polymer used in 3D printing and injection moulding. It is made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. The proportions of each component can vary, resulting in different finished products. ABS is a popular choice for these applications due to its low production cost, ease of machining, and superior physical attributes.
ABS is well-suited for 3D printing because of its strength, durability, and impact resistance. It can be easily moulded, sanded, and shaped, making it ideal for creating functional objects and prototypes. However, ABS tends to warp during 3D printing due to its significant shrinkage and expansion with temperature changes. To mitigate this, printing within an enclosure on a heated print surface is recommended.
ABS is also commonly used in injection moulding due to its low melting point and ease of processing. The injection moulding process involves heating ABS resin until it melts and then injecting it under high pressure into a steel mould. This results in parts with superior strength, minimal voids, and excellent impact resistance. Injection-moulded ABS parts have a smooth finish and uniform strength, making them suitable for various applications.
The versatility of ABS allows it to be used in a broad spectrum of products, including computer keyboard keys, LEGO bricks, automotive components, protective headgear, and musical instruments. Its ability to withstand heating and cooling makes it highly suitable for recycling, and its low heat and electricity conductivity are advantageous for electrical insulation. However, ABS has limitations, such as poor solvent and fatigue resistance, and susceptibility to UV exposure and weathering.
Overall, ABS is a popular choice for 3D printing and injection moulding due to its low cost, ease of processing, and superior physical properties. Its versatility and durability make it suitable for a wide range of applications across multiple industries.

ABS has excellent impact resistance and gloss
Acrylonitrile Butadiene Styrene (ABS) is a common thermoplastic polymer that is used in a wide variety of industries. ABS is derived from the combination of acrylonitrile, butadiene, and styrene. The different amounts of each monomer can be added to the process to vary the finished product, contributing to the popularity of ABS across several industry sectors.
ABS is advantageous in a wide variety of industries, although certain physical limitations restrict its use in some products and applications. ABS has a low melting point, which enables its easy use in the injection moulding process and 3D printing. However, its low melting point also renders it inappropriate for high-temperature applications and medical implants.
ABS has excellent impact resistance and can absorb shock effectively and reliably. The butadiene particles are elastic and make ABS impact resistant. The impact resistance can be amplified by increasing the proportion of polybutadiene in relation to styrene and acrylonitrile, although this causes changes in other properties. ABS also has high tensile strength and is very resistant to physical impacts and chemical corrosion, allowing the finished plastic to withstand heavy use and adverse environmental conditions.
ABS also has excellent gloss. The styrene gives the plastic a shiny, impervious surface, as well as hardness, rigidity, and improved processing ease. The glossy surface finish of ABS is highly compatible with a wide range of paints and glues. ABS plastics take colour easily, allowing finished products to be dyed in exact shades to meet precise project specifications.
