ABS granules stands for Acrylo Nitrile Butadyne Styrene granules. Their chemical composition render them the physical properties like hardness, rigidity and the tendency to remain tough even at low temperatures. These ABS Granules consist of particles of a rubber like toughener suspended in a continuous phase of styrene acrylo nitrile (SAN) copolymer. In market, the various grades of these amorphous, medium-priced thermoplastics with different levels of impact strength, heat resistance, flame retardance and plat ability are easily available. Generally, most of the naturally occurring ABS Granules are translucent to opaque and they can be pigmented to almost any color. The various grades of granules are meant for injection molding, extrusion, blow molding, foam molding and thermoforming. These molding and extrusion grades provide surface finishes ranging from satin to high gloss. The surface roughness of thermoplastic parts is a very crucial aspect as it directly affects the optical behavior and the aesthethics of the plastic products. As per the requirement and the usage, the surface roughness of these granules varies from product to product. For instance, in several fibre products such as optical discs etc, the surface roughness are required to keep to the least possible level.
In the present scenario, ABS Granules are one of the most important engineering ingredients of the plastic products. Its physical and chemical properties contributes to its popularity among the manufacturers. Automobile industry has been one of the prominent users of ABS granules. After the sudden fall in consumption of ABS Granules during 1998-1990 by automobile industry , the last decade has seen an uptrend in the consumption projections.

Advantage:
1. These granules offer a good balance of tensile strength to the manufacturers.
2. The impact and abrasion resistance are also comparatively better than other chemical substances.
3. The dimensional stability and surface hardness make them a preferred choice among manufacturers particularly in automobile industry.
4. The rigidity, heat resistance and low-temperature properties is an added advantage.
5. The chemical resistance and electrical characteristics make them popular in manufacturing purposes.

Applications & Usage:
1. After a sudden decline in 1998 and 1990, consumption of ABS (Acrylo Nitrile Butadyne Styrene) granules began to scale up in last few years. Presently, It is widely used in automobile industry.
2. Housing (shavers, vacuum cleaners, food processors)
3. In the manufacturing of Electronic parts
4. Used in manufacturing of Home appliances
5. Used for making wheel covers
6. Used For making radiator grill
7. Used In making of lamp housings
8. Used for making pipes & fittings
9. Used in ventilation & air conditioning spare parts
