Summary of information: The modification of PP materials is generally achieved by adding minerals to enhance toughness, weather resistance, glass fiber, flame retardancy, and super toughness. Each type of modified PP is widely used in the field of household appliances. It can also be used to manufacture high-speed washing machine barrels, rollers, and pulleys to meet their high mechanical performance requirements. It is used in places with high temperature resistance requirements such as rice cooker bases and handles, electronic microwave ovens, etc.

As one of the four general plastic materials, PP has excellent comprehensive performance, good chemical stability, good molding and processing performance, and relatively low price; But it also has disadvantages such as low strength, mold, low hardness, poor low-temperature impact resistance, large molding shrinkage, and easy aging. Therefore, it is necessary to modify it to meet the needs of the product. Therefore, it is necessary to modify it to meet the needs of the product.

Modification Approaches for Modified Polypropylene

The modification of PP materials is generally achieved by adding minerals to enhance toughness, weather resistance, glass fiber, flame retardancy, and super toughness. Each type of modified PP is widely used in the field of household appliances.

Comparison of Physical Properties between Modified Polypropylene and ABS

Generally speaking, the tensile strength of PP materials is between 20M and 30MPa, the bending strength is between 25M and 50MPa, and the bending modulus is between 800M and 1500MPa. When using PP in engineering structural components, glass fiber must be used for reinforcement.

Generally speaking, the mechanical properties of PP products reinforced with glass fibers can be doubled or even doubled. Specifically, the tensile strength reaches 65MPa~90MPa, the bending strength reaches 70MPa~120MPa, and the bending modulus reaches 3000MPa~4500MPa. This mechanical strength is comparable to ABS and reinforced ABS products, and is more heat-resistant.

The heat resistance temperature of ABS and reinforced ABS is generally between 80 ℃~98 ℃, while the heat resistance temperature of glass fiber reinforced PP material can reach 135 ℃~145 ℃. It can be used to manufacture axial and cross flow fans in refrigerators, air conditioners, and other refrigeration machines, and its cost is much lower than ABS reinforced products.

Application Prospects of Modified Polypropylene

Modified PP can also be used to manufacture inner barrels, rollers, and pulleys of high-speed washing machines to meet their high mechanical performance requirements, and is used in areas with high temperature resistance requirements such as rice cooker bases and handles, electronic microwave ovens, etc.

Modified PP has good application prospects in the home appliance industry. On the one hand, China has become the world's home appliance production center, with a group of influential production enterprises that can actively choose materials; On the other hand, industry competition also encourages companies to use more cost-effective materials.

Reinforced polypropylene: According to the different materials added, it can be divided into glass fiber reinforced, carbon fiber reinforced, inorganic powder filled, and glass fiber/inorganic powder reinforced. Mainly used for containers, electronic appliances, daily necessities structural components, home appliance structural components, fan blades, paddle blades, vacuum cleaner components, refrigerator internal components, etc.

Flame retardant polypropylene: Environmentally friendly flame retardant polypropylene, with a flame retardant grade of V0, mainly used for components with flame retardant requirements in electronic appliances such as microwave ovens, pressure cookers, and rice cookers. Halogen-free flame retardant polypropylene material, with a flame retardant grade of UL94-V0, environmentally friendly, mainly used in household appliances, automotive flame retardant components, electronic appliances, and components with flame retardant requirements.

High gloss polypropylene: High gloss heat-resistant polypropylene, high gloss spray free polypropylene, high gloss assisted molding polypropylene, low shrinkage high gloss polypropylene, low odor high gloss polypropylene, mainly used for small household appliance shells, bathrooms, foot basins, toilet covers, etc.

Heat-resistant polypropylene: mainly used for rice cooker covers, middle rings, rice cooker steamers, spoons, microwave door frames, dishwasher components, household appliance internal components, etc.

High impact polypropylene: mainly used for refrigerator components, turnover boxes, seats, etc.

Anti static polypropylene: mainly used for home appliance shells, industrial, daily necessities components, electronic component packaging materials, etc.

Weathering resistant polypropylene: mainly used for outdoor air conditioning components, outdoor flooring, outdoor products, etc.

From the above, it can be seen that there are many ways to modify PP, with a wide variety of modified polypropylene types and wide applications. PP can be used to prepare specialized materials and meet the different requirements of various industries. Therefore, the modification of PP is rapidly developing, becoming a new material with a wide variety of modified plastics and wide applications.
