What is it?ABS (Acrylonitrile-butadiene-styrene ) is tough, resilient, and easilymolded. It is usually opaque, although some grades can now be transparent, and it

can be given vivid colors. ABS-PVC alloys are tougher than standard ABS and, inself-extinguishing grades, are used for the casings of power tools.

Design guidelines. ABS has the highest impact resistance of all polymers. Ittakes color well. Integral metallics are possible (as in GE Plastics' Magix.) ABS is UVresistant for outdoor application if stabilizers are added. It is hygroscopic (may need

to be oven dried before thermoforming) and can be damaged by petroleum-basedmachining oils.

ABS can be extruded, compression moulded or formed t o sheet that is then vacuumthermo-formed. It can be joined by ultrasonic or hot-plate welding, or bonded withpolyester, epoxy, isocyanate or nitrile-phenolic adhesives.

Technical notes.ABS is a terpolymer - one made by copolymerising 3 monomers: acrylonitrile, butadiene and syrene. The

acrylonitrile gives thermal and chemical resistance, rubber-like butadiene gives ductility and strength, the styrene gives aglossy surface, ease of machining and a lower cost. In ASA, the butadiene component (which gives poor UV resistance) isreplaced by an acrylic ester. Without the addition of butyl, ABS be comes, SAN - a similar material with lower impactresistance or toughness. It is the stiffest of the thermoplastics and has excellent resistance to acids, alkalis, salts and manysolvents.

Typical Uses. Safety helmets; camper tops; automotive instrument panels and other interior components; pipe fittings;home-security devices and housings for small appliances; communications equipment; business machines; plumbing

hardware; automobile grilles; wheel covers; mirror housings; refrigerator liners; luggage shells; tote trays; mower shrouds; boathulls; large components for recreational vehicles; weather seals; glass beading; refrigerator breaker strips; conduit; pipe fordrain-waste-vent (DWV) systems.

The environment. The acrylonitrile monomer is nasty stuff, almost as poisonous as cyanide. Once polymerized withstyrene it becomes harmless. ABS is FDA compliant, can be recycled, and can be incinerated t o recover the energy itcontains.
