Typically, the tensile strength of PP materials ranges between 20-30 MPa, with the bending strength falling between 25-50 MPa, and the bending modulus between 800-1500 MPa. To use PP modified plastics in engineering structural components, glass fiber reinforcement is a must.

In general, the mechanical properties of PP modified plastics reinforced with glass fiber can be doubled or even tripled. Specifically, the tensile strength reaches 65-90MPa, the flexural strength reaches 70-120MPa, and the flexural modulus reaches 3000-4500MPa. Such mechanical strength is fully comparable to ABS and reinforced ABS products, and is also more heat-resistant.

Standard ABS and reinforced ABS have heat resistance ranging from 80 to 98°C, whereas glass fiber-reinforced PP modified plastics can reach up to 135 to 145°C. They are suitable for making axial fans and centrifugal fans in refrigeration equipment like refrigerators and air conditioners, offering significant cost savings compared to ABS reinforced products. Moreover, they can also be used to manufacture the inner drums, agitators, and belt pulleys of high-speed washing machines to meet their high mechanical performance requirements, as well as for items like rice cookers, handles, and electronic microwave ovens that demand high heat resistance.
