Compared with glass fiber reinforced PP and ABS, whose physical properties are better?

Mechanical properties of PP

The tensile strength of general PP materials is between 20M~30MPa, the bending strength is between 25M~50MPa, and the bending modulus is between 800M~1500MPa. If you want to use PP in engineering structural parts, you must use glass fiber for reinforcement.

Mechanical properties of glass fiber reinforced PP

After PP is reinforced and modified by glass fiber, the mechanical properties can be improved by multiples or even several times; the tensile strength of glass fiber reinforced modified PP has reached 65MPa~90MPa, the bending strength has reached 70MPa~120MPa, and the bending modulus has reached 3000MPa~4500MPa, this kind of mechanical strength is completely comparable to ABS and reinforced ABS products.

Comparison of heat-resistant temperature between glass fiber reinforced PP and ABS

Moreover, glass fiber reinforced PP is more heat-resistant than general ABS and reinforced ABS. Generally, the heat-resistant temperature of ABS and reinforced ABS is between 80°C and 98°C, while the heat-resistant temperature of glass fiber reinforced PP materials can reach 135°C to 145°C.

Application range of glass fiber reinforced PP

Glass fiber reinforced PP can be used to make axial fans and cross-flow fans in refrigerators, air conditioners, and other refrigeration machines, and its cost is much lower than that of ABS reinforced products.

In addition, it can also be used to manufacture inner tubs, pulsators, and pulleys of high-speed washing machines to meet their high requirements for mechanical performance, and rice cooker bases and handles, electronic microwave ovens, and other places that require high-temperature resistance.
