The Main Performance Of ABS Sheet
Jun 25, 2021
ABS has excellent mechanical properties, excellent impact strength, and can be used at extremely low temperatures; ABS has excellent wear resistance, good dimensional stability, and oil resistance, and can be used for bearings under medium loads and speeds. The creep resistance of ABS is larger than PSF and PC, but smaller than PA and POM. The flexural strength and compressive strength of ABS are inferior among plastics. The mechanical properties of ABS are greatly affected by temperature.
ABS is not affected by water, inorganic salts, alkalis and many kinds of acids, but it is soluble in ketones, aldehydes and chlorinated hydrocarbons. It will cause stress cracking when corroded by glacial acetic acid and vegetable oil. ABS has poor weather resistance and is easily degraded under the action of ultraviolet light; after half a year outdoors, the impact strength has dropped by half.
ABS sheet has excellent impact strength, good dimensional stability, dyeability, good molding and machining, high mechanical strength, high stiffness, low water absorption, good corrosion resistance, simple connection, non-toxic and tasteless, and has excellent Chemical properties and electrical insulation properties. It can be heat resistant and not deformed, and has high impact toughness under low temperature conditions. It is also a hard, hard-to-scratch and hard-to-deform material. Low water absorption; high dimensional stability. The conventional ABS board is not very white, but the toughness is very good. It can be cut with a shearing machine or punched with a die.
The heat distortion temperature of ABS is 93~118℃, and the product can be increased by about 10℃ after annealing. ABS can still show a certain degree of toughness at -40℃, and can be used in the temperature range of -40~100℃.
Among them, transparent ABS board has very good transparency and excellent polishing effect. It is the preferred material to replace PC board. Compared with acrylic, its toughness is very good, which can meet the delicate processing of products. The disadvantage is that transparent ABS is relatively expensive .
