Acrylonitrile-Butadiene-Styrene (ABS)ThermoplasticTrade Names• Cevian• Cycolac• Lustran• Magnum• Shinko-Lac• Taitalac• ToyolacManufacturerHoescht CelaneseGeneral ElectricMonsanto ChemicalDow ChemicalMitsubishi RayonTaita Chemical Co.Toray IndustriesGeneral DescriptionABS is a generic name for a versatile family of amorphous thermoplasticsproduced by combining three monomers, acrylonitrile, butadiene, andstyrene. The ratio of these monomers, as well as the molecular structure,can be manipulated to optimize the characteristics of the resultingpolymer. Acrylonitrile contributes chemical resistance and thermalstability. Butadiene contributes product toughness, impact resistance,and property retention at low temperatures. Styrene contributes rigidity,surface appearance, and processability. The resultant polymer’sproperties can vary over a large range to suit the manufacturer’s needs.For this reason, ABS is widely used in countless applications throughoutindustry. Specialty grades available include general purpose, glass filled,electroplateable, heat resistant, clear, high and low gloss, structural foam,and flame retardant grades. In 2004, the price of ABS ranged from $1.25to $3.00 per pound at truckload quantities.General PropertiesABS offers an excellent combination of toughness and rigidity at a lowcost. Typical notched impact strength ranges from 0.5 to 12 ft.-lb./in.(2.7 to 64.8 kg cm/cm), while typical tensile modulii range from200,000 to 1,200,000 psi (14,000 to 84,000 kg/cm 2 ). In addition to itstoughness, ABS has a high dimensional stability (which permits tightmold tolerances), a pleasing surface appearance, and is very easy toprocess. ABS is a relatively good electrical insulator and is suitable forsecondary insulating applications. ABS is chemically resistant to acidsand bases, but is not recommended for use with esters, ketones, oraldehydes. ABS has poor resistance to UV exposure, resulting insignificant changes in its appearance and mechanical properties. Toaddress this limitation, there are protective coatings available whichenhance ABS’s resistance to UV degradation. Some grades of ABS arecreated by adding a fourth monomer, such as the addition of alphamethyl styrene to create a heat resistant grade. Clear grades arecreated by adding methyl methacrylate, giving ABS the ability totransmit 75 to 80% of light.Typical Properties ofAcrylonitrile-Butadiene-Styrene (ABS)American EngineeringProcessing Temperature 400°F to 525°F 204°C to 274°CLinear Mold Shrinkage 0.002 to 0.007 in./in. 0.002 to 0.007 cm/cmMelting Point – –Density 63.7 to 79.9 lb./ft. 3 1.02 to 1.28 g/cm 3Tensile Strength, Yield 4.6 to 7.9 lb./in. 2 x 10 3 3.2 to 5.6 kg/cm 2 x 10 2Tensile Strength, Break 4.0 to 12.0 lb./in. 2 x 10 3 2.8 to 8.4 kg/cm 2 x 10 2Elongation, Break 1.0 to 50.0% 1.0 to 50.0%Tensile Modulus 2.0 to 12.0 lb./in. 2 x 10 5 1.4 to 8.4 kg/cm 2 x 10 4Flexural Strength, Yield 6.2 to 20.0 lb./in. 2 x 10 3 4.4 to 14.1 kg/cm 2 x 10 2Flexural Modulus 2.5 to 4.4 lb./in. 2 x 10 5 1.8 to 3.1 kg/cm 2 x 10 4Compressive Strength 6.0 to 17.0 lb./in. 2 x 10 3 4.2 to 12.0 kg/cm 2 x 10 2Izod Notched, R.T. 0.5 to 12.0 ft-lb./in. 2.7 to 64.8 kg cm/cmHardness R95 - R125 Rockwell R96 - R125 RockwellThermal Conductivity 1.2 to 1.6 BTU-in./hr.-ft. 2 -°F 0.17 to 0.23 W/m-°KLinear ThermalExpansionDeflection Temperature@ 264 psiDeflection Temperature@ 66 psiContinuousService Temperature1.1 to 5.7 in./in.-°F x 10 -5 2.0 to 10.3 cm/cm-°C x10 -5Typical Applications• Medical – Piercing pins, clamps, filter casings, stopcocks,check valves, blood dialyzers• Miscellaneous – Appliances, business machines, telephones,luggage, power tools, bathtubs, pipe fittings, toys, faucets, showerheads, sporting goods, automotive applicationsSI170°F to 240°F 77°C to 116°C190°F to 245°F 88°C to 118°C130°F to 180°F 54°C to 82°CDielectric Strength 350 to 500 V/10 -3 in. 1.4 to 2.0 V/mm x 10 4Dielectric Constant@ 1 MHzDissipation Factor@ 1 MHzWater Absorption,24 hr.3.1 to 3.4 3.1 to 3.40.008 to 0.009 0.008 to 0.0090.1 to 0.5% 0.1 to 0.5%20The Loctite ® Design Guide for Bonding Plastics, Volume 4

The bond strengthsachieved by Loctite ® H3000 and H4500 Speedbonder Structural Adhesives, 3030 Adhesive, Loctite ®E-90FL and E-20HP Hysol ® Epoxy Adhesives, and Loctite ® 3631 Hysol ® Hot Melt Adhesive did notachieved substrate failure but performed exceptionally well. However, the addition of an antistatic agentresulted in a large, statistically significant increase in the bond strengths achieved on ABS. Loctite ® 1942 Hysol ® and Loctite ® 7804 Hysol ® Hot Melt Adhesives consistently achieved the lowest bond strengths.Surface TreatmentsSurface roughening caused a statistically significant increase in the bond strengths achieved when usingLoctite ® 380 Black Max ® Instant Adhesive and Loctite ® 330 Depend ® Adhesive. The effect of surfaceroughening could not be determined for Loctite ® 401 Prism ® , 4011 Prism ® and 414 Super Bonder ®Instant Adhesives and Loctite ® 3105 and 3311 Light Cure Adhesives because the bonds created by theseadhesives were stronger than the ABS substrate for both the treated and untreated ABS. Likewise, the effectof using Loctite ® 770 Prism ® Primer, in conjunction with Loctite ® 401 Prism ® Instant Adhesive, or Loctite ®4011 Prism ® Medical Device Instant Adhesive with Loctite ® 7701 Prism ® Primer, could not be determined.Other Important Information• ABS can be stress cracked by uncured cyanoacrylate adhesives, so any excess adhesiveshould be removed from the surface immediately.• ABS is compatible with acrylic adhesives, but can be attacked by their activators beforethe adhesive has cured. Any excess activator should be removed from the surface immediately.• ABS is incompatible with anaerobic adhesives.• Surface cleaners: isopropyl alcohol, Loctite ® ODC-Free Cleaner & Degreaser.NOTES: The force applied to the tests specimens exceededthe strength of the material resulting in substrate failurebefore the actual bond strength achieved by theadhesive could be determined.† Due to the severe deformation of the block shearspecimens, testing was stopped before the actual bondstrength achieved by the adhesive could be determined(the adhesive bond never failed).3002.13002.13002.13002.1NOT TESTED: Substrate melted at adhesivecure temperature.3002.1The addition of the indicated additive (or surfaceroughening) caused a statistically significant decrease inthe bond strength within 95% confidence limits.The addition of the indicated additive (or surfaceroughening) caused a statistically significant increasein the bond strength within 95% confidence limits.The Loctite ® Design Guide for Bonding Plastics, Volume 4 21
