  1.General performance

  The appearance of ABS engineering plastic is opaque and ivory-colored granules,and its products can be colored and have high gloss.The relative density of ABS is about 1.05,and the water absorption is low.ABS has a good combination with other materials and is easy to surface print,coating and plating treatment.The oxygen index of ABS is 18-20,which is a flammable polymer.The flame is yellow,has black smoke,and emits a special cinnamon smell.

  2,mechanical properties

  ABS has excellent mechanical properties,and its impact strength is very good.It can be used at extremely low temperatures:ABS has excellent abrasion resistance,good dimensional stability,and oil resistance.It can be used for bearings under medium loads and speeds.ABS has higher creep resistance than PSF and PC,but less than PA and POM.The flexural strength and compressive strength of ABS are the worst among plastics.The mechanical properties of ABS are greatly affected by temperature.

  3.Thermal performance

  The thermal deformation temperature of ABS is 93~118℃,and the product can be increased by about 10℃after annealing treatment.ABS can still show a little toughness at-40℃,and it can be used in the temperature range of-40~100℃.

  4.Electrical performance

  ABS has good electrical insulation and is almost independent of temperature,humidity and frequency.It can be used in most environments.

  5.Environmental performance

  ABS is not affected by water,inorganic salts,alkalis,and various acids,but is soluble in ketones,aldehydes,and chlorinated hydrocarbons.Stress cracking will occur due to erosion by glacial acetic acid and vegetable oil.ABS has poor weather resistance and is prone to degradation under the action of ultraviolet light;after half a year outdoors,the impact strength is reduced by half.
