What is a PP board?
PP board is the abbreviation for polypropylene sheet, which is a semi crystalline thermoplastic sheet.
Advantages of PP board
Good mechanical performance. It has high strength, hardness, and toughness. Its tensile strength is generally between 30-40 MPa, and it can withstand certain external forces without deformation. In industrial applications, such as making protective plates for chemical equipment, they can effectively resist collisions and impacts.
Good water resistance. PP board hardly absorbs water, and its water absorption rate is generally less than 0.01%. This enables it to maintain stable performance for a long time in environments that come into contact with water, such as water tanks, pipes, and water-based buildings, without deformation or mold caused by water absorption.
Limitations of PP board
Limited wear resistance. Due to insufficient surface hardness, the wear resistance of PP board is also poor. In application scenarios that require repeated friction, PP boards may not be able to meet long-term usage requirements due to rapid wear.
Physical performance degradation. Low temperature not only causes PP board to become brittle, but also deteriorates its other physical properties. For example, its impact resistance strength will be significantly reduced, and PP boards that were originally able to withstand a certain impact force may be damaged due to minor collisions at low temperatures. In some mechanical components or packaging materials that require use in low-temperature environments, this performance degradation may lead to product failure.
The main function of the PP board
PP board has functions such as mechanical protection, chemical protection, physical and electrical isolation, load-bearing, and packaging. It can play an important role in the fields of industry, construction, electronic appliances, warehousing and logistics, protecting equipment, isolating substances, carrying heavy objects, and providing good packaging for products.
The working principle of the PP board
PP board mainly relies on its tight internal molecular structure and stable chemical properties, which can resist external impact and chemical corrosion in terms of protection; As an isolation material, it can block physical and electrical currents; With a certain strength, it can support heavy objects when carrying; As a packaging material, it utilizes toughness and strength to protect the product.
There are various types of PP board , how to choose the one that suits you
一、Pay attention to processing performance and installation convenience
1.Processing performance. If complex processing such as cutting, drilling, bending, etc. is required for PP boards, it is necessary to choose PP boards with good processing performance. PP boards that are easy to process have smooth edges, are not easily broken during operation, and can be easily processed into various shapes.
2.Installation convenience. For the installation of some large PP board products, such as building exterior wall decorative panels and protective panels for large equipment, it is necessary to choose PP boards that are easy to install. For example, PP boards that are lighter in weight and can be installed using simple connection methods such as buckles, glue, etc. would be more suitable.
二、Consider cost and cost-effectiveness
On the premise of meeting performance requirements, cost is also an important factor. The prices of PP boards of different brands and specifications vary greatly. If it is a large-scale application, such as a large number of pipeline liners or packaging materials in industrial production, it is necessary to comprehensively compare the prices and performance of different PP boards, and choose products with high cost-effectiveness to reduce overall costs.
三、Based on application functional requirements
1.Protective function. If used for mechanical protection, such as protective barriers for machinery and equipment, PP boards with high strength and toughness are required. PP boards with high tensile strength and impact strength can be selected to effectively resist collisions and impacts. If used for chemical protection, such as chemical container liners, more attention should be paid to their chemical corrosion resistance, and PP boards with good resistance to the chemicals they contain should be given priority consideration.
2.Load bearing function. When PP board is used to carry heavy objects such as shelf partitions and pallets, the appropriate PP board should be selected according to the load capacity. When carrying heavy loads, it is necessary to choose PP boards with higher density and strength to ensure that they will not deform or be damaged under long-term heavy loads.
四、Consider the usage environment
1.Temperature environment. If PP boards are used in high-temperature environments, such as protective boards near heating equipment, it is necessary to choose PP boards that can withstand higher temperatures, with a melting point higher than the maximum temperature of the usage environment, to avoid softening and deformation. In low-temperature environments, such as outdoor facilities in cold regions, it is necessary to choose PP boards that have good cold resistance and will not significantly reduce toughness at low temperatures to prevent brittleness and fracture.
2.Chemical environment. In scenarios where chemical substances come into contact, such as chemical pipelines and reactor liners, the selection should be based on the type and concentration of the chemicals in contact. For strong acidic and alkaline environments, PP boards with strong chemical corrosion resistance should be selected; If it is possible to come into contact with organic solvents, make sure that the PP board does not swell or dissolve in these solvents.
