ABS has better impact strength, abrasion resistance, rigidity and hardness than PP, but PP also has relatively good tensile strength and rigidity.PP can withstand higher temperatures, with a heat distortion temperature of 80 to 100 degrees Celsius, and can be cooked in boiling water, while ABS is less heat-resistant, generally around 70 to 80 degrees Celsius.The electrical insulation of ABS is better than that of PP, and is not affected by temperature, humidity and frequency, while PP's electrical insulation is poor, easy to moisture and aging.PP has better corrosion resistance than ABS, resistant to water, inorganic salts, alkalis and acids, insoluble in most alcohols and hydrocarbon solvents, while ABS's corrosion resistance is poor, easy to organic solvents and strong acids and alkalis erosion.ABS is widely used in electronic products, automotive parts, construction materials, medical equipment and other fields, while PP is ABS is widely used in chemical equipment, automotive parts, medical devices, etc. The price of ABS is relatively high, mainly because of its complex production process, which requires the use of a variety of raw materials polymerization, compared to the price of PP is relatively low, mainly because of its simple production process, the use of propylene monomer polymerization.
