- Chemical and Thermal Stability: The acrylonitrile in ABS provides chemical and thermal stability, while the butadiene adds toughness and strength. This stability makes it suitable for various applications, such as protective housing for power tools and medical equipment.
- Aesthetic and Finish: The styrene in ABS gives the finished polymer a glossy and aesthetically pleasing finish. It is also lightweight and comes in a variety of colours and textures, making it versatile for different product designs.
- Cost-Effectiveness: ABS plastic is relatively cheap to produce due to its simple manufacturing process. This cost-effectiveness translates into lower consumer costs and increased sales potential.
- Recyclability: ABS plastic can withstand being heated and cooled multiple times, making it ideal for recycling. However, it is important to ensure proper recycling to prevent ABS products from contributing to plastic pollution.
Cons of ABS Plastic:
- Low Melting Point: Despite its strength, ABS plastic has a relatively low melting point compared to other plastics. This makes it unsuitable for high-temperature applications and medical implants.
- Poor UV, Solvent, and Weather Resistance: ABS plastic has limited resistance to UV light, solvents, and weathering. When exposed to sunlight for extended periods, it may discolour and crack unless properly protected with coatings or other materials.
- Emissions during Processing: During processes like 3D printing or injection molding, ABS can produce dangerous fumes or smoke. Studies have linked these emissions to cytotoxicity, oxidative stress, and inflammation. Proper ventilation or the use of a fume hood is essential when working with ABS plastic.
- Use of Petroleum-Based Materials: The production of ABS plastic involves the use of petroleum-based materials, which contributes to carbon emissions. This is a consideration for environmentally conscious consumers and manufacturers.

Casio's use of ABS plastic
Casio has been manufacturing electronic musical keyboards since 1979, and its products are used by beginners and professionals alike. The company's mission is to enable anyone to enjoy making music, regardless of their age, skill level, or budget. Casio's range of products includes portable keyboards, stage pianos, and console pianos. Their keyboards are designed to be compact, lightweight, and affordable, often featuring plastic keys.
While I cannot confirm that Casio uses ABS plastic specifically, it is known that the company's keyboards are made of lightweight plastic. This is either a positive or negative aspect, depending on the user's needs. Casio's plastic keyboards are aimed at beginners, and they often come with many bonus features, such as accompaniment rhythms, preset songs, sound banks, and connectivity options.
The SA-series, for example, is designed for children with its mini keys and fun sounds and rhythms. The CTK-series is a starter keyboard with 61 full-size touch-response keys, while the LK-series offers full-size lighted keys for easy learning. The CTK-3500 model is recommended for those who plan to study piano seriously, as it offers touch-sensitive keys and a USB port for MIDI connectivity.
Casio's more advanced pianos, such as the Privia series, offer a more polished experience with weighted keys and improved sound quality. These digital pianos are designed to be slim yet polished, using redesigned slim-form keys and updated sound engines. Overall, Casio's use of plastic, whether it be ABS or another type, has allowed the company to create affordable, lightweight, and durable keyboards that have become a staple for musicians of all skill levels.

Other plastics used for keycaps
While ABS is the most common plastic used for keycaps, there are several other types of plastics used as well. These include Polybutylene Terephthalate (PBT), Polyvinyl Chloride (PVC), Polycarbonate (PC), and Polystyrene blends. Each of these plastics has unique properties that make them suitable for specific applications.
PBT keycaps, for instance, are less common but usually higher quality than ABS. They have a textured feel and are more durable, making them less prone to wear and tear. PBT is also used for double-shot keycaps, which are designed to let the backlighting shine through the legends, making them easier to read.
PVC is another relatively hard plastic that is used for keycaps. It is widely used by mass-market brands such as Logitech, Dell, and HP. However, the production of PVC is considered environmentally unfriendly and is not manufactured in some parts of the world.
Polycarbonate (PC) is a tough, optically clear or opaque, biocompatible plastic with good thermal resistance. It is ideal for applications that require impact resistance and clarity, such as car headlights, eyeglasses, and medical equipment. PC is mostly used for clear and transparent keycaps, and it does not yellow like ABS or polystyrene.
Polystyrene blends, including ABS, will gradually turn yellow when exposed to ultraviolet light or sunlight. This yellowing occurs faster if the plastic contains flame-retardant chemicals. While ABS is commonly used for keycaps, polystyrene blends are more often used in the plastic of keyboard cases.

Pros and cons of other plastics
When compared to other plastics, ABS (short for Acrylonitrile Butadiene Styrene) stands out for its versatility and wide range of applications. It is a thermoplastic polymer that is widely used in various industries, including consumer goods, electronics, automotive parts, and toys. However, it is not without its drawbacks, and several other plastics, such as polystyrene (PS), polypropylene (PP), polyethylene, PLA, and Sulapac, offer distinct advantages and disadvantages.
Polystyrene (PS) shares similarities with ABS in terms of transparency, ease of processing, and affordability. However, PS falls short in impact resistance and mechanical strength, making it less suitable for applications requiring durability. PS is commonly used for packaging materials, disposable cutlery, and insulation.
Polypropylene (PP) is another thermoplastic that shares similarities with ABS. While it offers good impact resistance and versatility, specific advantages and disadvantages over ABS are not readily available.
Polyethylene, like ABS, is a versatile thermoplastic polymer with a broad range of applications. It is lightweight, durable, cost-effective, easy to handle, and highly water-resistant. Polyethylene has excellent electrical insulation properties and is suitable for both indoor and outdoor use. However, it has lower heat resistance and chemical resistance than some other plastics, and it requires proper additives to be suitable for food contact applications.
PLA (Polylactic Acid) is a biodegradable alternative to ABS, sourced from natural crops like sugarcane or corn. It boasts excellent printing properties, good solvent resistance, and ease of use in 3D printing. PLA is also safe for human use and is approved by the FDA for medical applications. On the downside, PLA has lower heat resistance than ABS, making it unsuitable for high-temperature components, and it tends to be more expensive.
Sulapac, an award-winning material innovation company, offers sustainable alternatives to conventional plastics. Their materials, such as Sulapac Luxe and Luxe Flex, have similar mechanical properties to ABS but eliminate toxic substances and persistent microplastic pollution. Sulapac materials have high bio-based content, contributing to a lower carbon footprint, and are efficiently recyclable.
In summary, while ABS plastic offers versatility, durability, and impact resistance, other plastics like polystyrene, polypropylene, polyethylene, PLA, and Sulapac provide unique advantages in terms of affordability, biodegradability, heat resistance, electrical insulation, and sustainability.
