Introduction to ABS Features

ABS is a kind of resin with very good comprehensive performance. It has high impact strength and surface hardness in a relatively wide temperature range. The thermal deformation temperature is higher than PA and PVC, and the dimensional stability is good.  

1. The fluidity of ABS melt is better than PVC and PC, but worse than PE, PA and PS, similar to POM and HIPS.  The flow characteristics of ABS belong to non-Newtonian fluid, and the melt viscosity is related to the processing temperature and shear rate, but is more sensitive to the shear rate.  

2, mechanical properties ABS has excellent mechanical properties, its impact strength is excellent, can be used at very low temperature.  Even if the ABS product is damaged, it can only be tensile damage rather than impact damage.  ABS has excellent wear resistance, good dimensional stability, and oil resistance, which can be used for bearings under medium load and speed.  The creep of ABS is larger than that of PSF and PC, but smaller than that of PA and POM.  The bending strength and compression strength of ABS are poor in plastics.  The mechanical properties of ABS are greatly affected by temperature.  

3, thermal properties ABS belongs to amorphous polymer, no obvious melting point;  Melt viscosity is high, liquidity is poor, weather resistance is poor, ultraviolet light can make color;  The thermal deformation temperature is 70-107 °C (about 85), and the product can be increased by about 10°C after annealing.  It is sensitive to temperature and shear rate.  ABS can still show some toughness at -40°C and can be used for a long time in the temperature range of -40°C to 85°C.  

4, electrical performance ABS electrical insulation is good, and almost not affected by temperature, humidity and frequency, can be used in most environments.  

5, environmental performance ABS is not affected by water, inorganic salts, alkali alcohols and hydrocarbon solvents and a variety of acids, but soluble in ketones, aldehydes and chlorinated hydrocarbons, by acetic acid, vegetable oil erosion will produce stress cracking.
