Acrylonitrile Butadienestyrene, popularly known as ABS granules is an engineering polymer that has great fluidity to take up any shape, and provides a good shine and colour. ABS stands out for its strong nature, thermal stability and its ability to conform to any rigid matrix. ABS is developed by polymerizing acrylonitrile and styrene, along with the presence of polybutadiene. The proportions vary, but the composition makes ABS more robust than pure polystyrene.
The most important properties of ABS are its durability and impact resistance feature, although various modifications can be made to amplify these properties. ABS has excellent stability under limited loads, and displays valuable characteristics within -20 °C to 80 °C.
ABS comes in two different grades – one for extrusion, and the other for injection moulding. However, ABS’ final properties are determined by the settings under which they have been processed. For instance, moulding at a lower temperature improves its strength, whereas moulding at a higher temperature enhances its gloss and shine. Certain additives can also be mixed to make it stronger, protect against ultraviolet radiation, prevent oxidisation, or change its colour.
ABS is largely used for mechanical purposes, but it also finds its way in electrical usages. Customers have a wide choice of colours and shades – each with their own key characteristics, allowing them to handpick or customise the granules, depending on their requirements. The blue and green granules are used for making any kind of plastic item. The yellow and orange granules have massive thermal stability, while the red granules are highly consistent in their composition. Violet granules are useful for the electrical industry. Given the extensive range, these granules have a high procurement demand from customers worldwide.
ABS polymers do not welt when exposed to alkalis, alcohols, hydrochloric/phosphoric/aqueous acids, and to vegetable/animal/mineral oils. Furthermore, ABS granules are light weight, and they do not get affected by atmospheric humidity or temperature (provided it’s within the acceptable range).
