ABS material has excellent comprehensive properties, it is hard, glossy, and easy to color, and it is widely used in various fields, also known as the "king of plastics".
ABS profile is a polymer formed by the copolymerization of three monomers, namely acrylonitrile A, butadiene B, and styrene S, referred to as ABS. 1,3-butadiene provides ABS with low-temperature extensibility and impact resistance; acrylonitrile provides ABS with properties such as hardness, heat resistance, and resistance to chemical corrosion by acids, alkalis, and salts; styrene can provide ABS with hardness, processing fluidity, and surface gloss.
From a morphology perspective, ABS is a non-crystalline material that has various characteristics, such as low-temperature resistance, impact resistance, low creep, excellent dimensional stability, and ease of processing, with high surface hardness and good chemical resistance. By changing the ratio of the above three components, various properties of ABS can be changed, and ABS is widely used as an engineering plastic.
ABS raw materials are light yellow or milky white pellets with some toughness, and the density is about 1.04-1.06 g/cm3. ABS has a relatively strong ability to resist the corrosion of acid, alkali, and salt and can tolerate organic solvent dissolution to a certain extent. It can be mixed with various resins to form a blend, such as PC/ABS, ABS/PVC, PA/ABS, PBT/ABS, etc., producing new properties and applications.
It has good moldability within the temperature range of -25℃ to 60℃, with a smooth surface on the processed product, easy to dye and electroplate, and is commonly used in daily necessities such as household appliances, toys, and the well-known "LEGO blocks".
ABS is non-toxic, tasteless, has low water absorption, can be made in various colors, and also has a high gloss of 90%. ABS has good adhesion with other materials, and surface printing, coating, and plating processing are not difficult. The oxygen index of ABS is 18.2, which belongs to a combustible polymer, with a yellow flame, black smoke, charred residue but no drops, and produces a special cinnamon smell. Adding flame retardant can make ABS a flame-retardant material, ensuring the safety and fire prevention of the finished product. At the same time, it is low in smoke during combustion, reducing environmental pollution.
ABS has high impact strength and surface hardness in a relatively wide temperature range. The heat distortion temperature is higher than PA and PVC, and the critical surface tension is 34-38mN/cm, with a shrinkage rate in the range of 0.4%-0.8%; if reinforced with glass fiber, it can be reduced to 0.2%-0.4%. The fluidity of ABS melt is better than PVC and PC, but worse than PE, PA, and PS. It is similar to POM and HIPS and belongs to a non-Newtonian fluid, more sensitive to shear rate.
Mechanical Properties: ABS has excellent mechanical properties, and its impact strength is excellent, which can be used at very low temperatures. Even if the ABS product is destroyed, it is only a tensile failure rather than impact failure. However, the mechanical properties of ABS are greatly affected by temperature. ABS has excellent wear resistance and is resistant to oil, so it can be used for bearings under medium loads and speeds. The creep of ABS is greater than that of PSF and PC, but smaller than that of PA and POM, and the flexural and compressive strengths are relatively poor among plastics.
Thermal Properties: ABS belongs to an amorphous polymer, with no obvious melting point, high melt viscosity, poor flowability and weather resistance; ultraviolet light can discolor ABS, and the heat distortion temperature is 70-107℃ (about 85℃), and the product can be improved by about 10℃ through annealing. However, ABS still has a certain toughness at -40℃ and can be used for a long time in a temperature range of -40℃ to 85℃, and the thermal decomposition temperature is above 270℃.
Electrical Properties: ABS has good electrical insulation, which is almost unaffected by temperature, humidity, and frequency and can be used in most environments.
Environmental Properties: ABS is not affected by water, inorganic salts, alkaline alcohols, and hydrocarbon solvents and many acids. However, it can be dissolved in ketones, aldehydes, and chlorinated hydrocarbons, and stress cracking occurs under the erosion of acetic acid, vegetable oil, etc. Under the action of ultraviolet light, ABS is prone to degradation, and after being placed outdoors for half a year, the impact strength decreases by half.
ABS has excellent properties, such as impact resistance, high rigidity, oil resistance, low-temperature resistance, resistance to chemical corrosion, electrical properties, and ease of processing, low price, and is widely used in the fields of electronics, instruments, automobiles, and construction industries.
