The three compounds that make up ABS are acrylonitrile, butadiene, and styrene. ABS’s performance is characterized by its toughness, stiffness, machinability, and impact strength even at low temperatures.
- ABS resins are terpolymers of acrylonitrile, butadiene, and styrene. These medium-priced, amorphous thermoplastics are hard, rigid, and tough – even at low temperatures. Various grades offer different levels of impact strength.
- Most natural ABS resins are translucent to opaque, but they are also produced in transparent grades and they can be pigmented to almost any color.
- ABS plastics offer a good balance of tensile strength, impact and abrasion resistance, dimensional stability, surface hardness, rigidity, heat resistance, low-temperature properties, chemical resistance, and electrical characteristics.
- ABS parts have enough spring to accommodate shallow, snap-fit assembly requirements.
- The impact properties of ABS are exceptionally good at room temperature. General-purpose ABS grades may be adequate for some outdoor applications – depending on design and performance requirements – but prolonged exposure to sunlight causes a colour change and can reduce surface gloss, impact strength, hardness, and elastic modulus.
- High rigidity.
- Good impact resistance, even at low temperatures.
- Good insulating properties.
- Good weldability.
- Good abrasion and stain resistance.
- High dimensional stability (Mechanically strong and stable over time)
- High surface brightness and excellent surface aspect.
