❓ Frequently Asked Questions
What is ABS (Acrylonitrile Butadiene Styrene)?
ABS is an amorphous thermoplastic polymer derived from the copolymerisation of three monomers: acrylonitrile (chemical and thermal resistance), butadiene (impact resistance), and styrene (rigidity, shine, ease of processing). This combination offers an excellent versatile compromise between cost and performance for many industrial applications.
What are the mechanical properties of ABS?
ABS offers good impact resistance even at low temperatures, medium rigidity, a tensile strength of 35 to 50 MPa, a Young's modulus between 1800 and 2500 MPa, and a Shore D hardness between 65 and 80. It deforms before breaking, showing good toughness.
What are the main industrial applications of ABS?
ABS is used for electronic enclosures, interior automotive parts, toys (notably LEGO), household appliances, furniture components, suitcases, and sanitary components. Its balance of cost, properties, and appearance makes it a go-to polymer in many consumer and professional industries.
What is the maximum operating temperature of ABS?
Standard ABS has a continuous service temperature of approximately 70 to 90°C, with a Heat Deflection Temperature (HDT) (under 1.82 MPa) between 85 and 100°C. Above 100°C continuously, ABS starts to deform. For higher temperatures, prefer a PC or a PC/ABS blend.
Is ABS recyclable?
Yes, ABS is technically recyclable and falls into the OTHER (code 7) category of plastics. There are supply chains for recycled ABS. Mechanical recycling preserves most of its mechanical properties for non-critical applications. Recycled ABS sees its properties slightly decrease with each processing cycle.
What are the limitations of ABS compared to other polymers?
ABS has poor resistance to UV (yellowing, gradual embrittlement), strong solvents like acetone and esters, and temperatures above 90°C. It is not transparent, except for specific grades. For these uses, prefer ASA (UV), PC (heat, transparency), or PMMA (pure transparency). Fibreglass-filled ABS rigidifies the assembly.
