Application of glass fiber reinforced modified polypropylene in household appliances

hips and ABS are the first plastic materials used in household appliances. Due to the high price of hips and ABS resins, foreign countries have gradually developed PP (polypropylene) modified materials suitable for household appliance parts, and partially replaced hips and ABS resins in household appliance products with their advantages of low cost, light weight and good performance

glass fiber reinforced modified PP

generally, the tensile strength of PP material 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

generally speaking, the mechanical properties of PP products reinforced by glass fiber can be doubled or even several times improved. Specifically, the tensile strength reaches 65mpa~90mpa, the bending strength reaches 70mpa~120mpa, and the bending modulus reaches 3000mpa~4500mpa. Such mechanical strength is completely comparable to ABS and reinforced ABS products, and it is more heat-resistant. Generally, the heat-resistant temperature of ABS and reinforced ABS is between 80 ℃ ~98 ℃, while the heat-resistant temperature of glass fiber reinforced PP material can reach 135 ℃ ~ a continuous flat plate production line of 145 ℃ has been established. It can be used to make axial flow fans and cross flow fans in refrigerators, air conditioners and other refrigeration machines, and its cost is much lower than that of ABS enhanced products. In addition, it can also be used to manufacture the inner barrel, wave wheel and belt pulley of high-speed washing machine to meet its high requirements for mechanical performance. It can also be used in places with high requirements for temperature resistance, such as rice cooker base, handle and electronic microwave oven

development trend and Prospect of modified PP

modified PP has a very good application prospect in the household appliance industry. On the one hand, China has become the production center of household appliances in the world, and has a number of influential production enterprises, which can actively choose materials; On the other hand, industry competition also urges enterprises to apply materials with more reasonable cost performance. From the perspective of the development of household appliance technology in the future, the humanization of household appliances will be more prominent, the product range will be more complete, and the traditional household appliances will develop towards miniaturization and large-scale. The continuous emergence of new products also puts forward higher requirements for PP modification. Modified PP will have four main development trends:

1 High rigidity, high gloss PP. This kind of product will be possible to replace PS and ABS in some household appliances, especially those with improved structural durability

2. Halogen free flame retardant PP. With the implementation of the European Union RoHS decree and the attention paid by all countries to environmental protection, the research and development of halogen-free flame retardant PP is urgent, and the market prospect is broad

3. Long glass fiber reinforced PP. Ordinary short glass fiber reinforced PP, because the glass fiber contained is short, easy to warp, low impact strength, easy to deform when heated, long glass fiber can overcome the above defects of short glass fiber, and the products have better surface, higher service temperature, higher impact strength, which can be applied to PolyOne to build a new factory in Pune, India in 2014 for refrigerators and kitchen appliances with high heat resistance

4. Antibacterial PP. This kind of plastic is a new functional polymer material with bactericidal and antibacterial properties. It can be used in washing machine liners and plastic parts in refrigerators, and has a broad prospect
