Acrylonitrile butadiene styrene (ABS) (chemical formula (C8H8· C4H6·C3H3N)n) is a common thermoplastic used to make light, rigid, molded products such as piping (for example plastic pressure pipe systems), musical instruments (most notably recorders and plastic clarinets), golf club heads (used for its good shock absorbance), automotive body parts, wheel covers, enclosures, protective head gear, buffer edging for furniture and joinery panels, airsoft BBs and toys, including Lego bricks[1]. ABS plastic ground down to an average diameter of less than 1 micrometer is used as the colorant in some tattoo inks. Tattoo inks that use ABS are extremely vivid. This vividness is the most obvious indicator that the ink contains ABS, as tattoo inks rarely list their ingredients[2].

Material Options
Plastic enclosure research has identified four main material options. One is most likely better suited than another, depending on the product function, but all offer great properties.
* ===ABS==== – Acrylonitrile, Butabiene and Styrene is known for its ability to withstand impact and heat as well as its ruggedness, plus it has electrical properties that are consistent over a wide range of frequencies.
* HIPS – High Impact Polystyrene is fairly rugged and inexpensive, but has reduced electrical properties.
* ====Polycarbonate==== & Acrylic – This material combination is impact and temperature resistant, plus it has improved optical properties for applications. Acrylic is a rugged material and highly transparent and resistant to ultraviolet radiation.
* Kydex – A PVC/Acrylic blend that is a tough material and heat resistant with a good appearance.*
