As a common logistics and transportation tool, the selection of raw materials for plastic pallets plays a crucial role in its performance and service life. Next, let's take a look at the material and raw material knowledge of plastic pallets.
First, the material of the plastic pallet.
The materials of plastic pallets are mainly divided into two types: polypropylene (PP) and polyethylene (PE). Among them, PP plastic pallets have high strength and heat resistance, and are suitable for some occasions that need to withstand heavy loads and high temperature environments; The PE plastic pallet has good toughness and impact resistance, and is suitable for some occasions that need to withstand frequent impact and vibration.
Second, the raw materials of plastic pallets.
1.Polypropylene (PP).
Polypropylene is a thermoplastic with a tight molecular chain structure and high crystallinity, so it has high mechanical strength and heat resistance. The raw materials of PP plastic pallets mainly include propylene monomer, catalysts, additives, etc. Among them, propylene monomer is the main component of PP plastics, and its quality and purity have a crucial impact on the performance of PP plastics. The catalyst is the key factor to promote the polymerization of propylene monomer, and its type and dosage have an important impact on the crystallinity and molecular weight distribution of PP plastics. Additives are additives used to improve the processing performance, weather resistance, and aging resistance of PP plastics.
2.Polyethylene (PE).
Polyethylene is a thermoplastic with a loose molecular chain structure, so it has good toughness and impact resistance. The raw materials of PE plastic pallets mainly include ethylene monomer, catalysts, additives, etc. Among them, ethylene monomer is the main component of PE plastics, and its purity and quality have an important impact on the performance of PE plastics. The catalyst is the key factor to promote the polymerization of ethylene monomer, and its type and dosage have an important impact on the molecular weight and crystallinity of PE plastics. Additives are additives used to improve the processing performance, weather resistance, and aging resistance of PE plastics.
Third, the selection of raw materials for plastic pallets.
When choosing raw materials for plastic pallets, the following aspects need to be considered:
1.Use environment: Different use environments have different requirements for the material and performance of plastic pallets. For example, plastic pallets used in high-temperature environments need to have high heat resistance and strength, while plastic pallets used in humid environments need to have good water resistance and corrosion resistance.
2.Load requirements: Different load requirements have different requirements for the material and thickness of plastic pallets. Generally speaking, plastic pallets that need to bear heavier loads need to choose materials with higher strength and rigidity, and appropriately increase the thickness of the pallet to improve its load-bearing capacity.
3.Service life: The service life of plastic pallets is closely related to the quality of their materials and raw materials. Therefore, when choosing the raw materials of plastic pallets, it is necessary to consider their performance in terms of aging resistance, weather resistance, etc., to ensure the service life of plastic pallets.
4.Cost considerations: Plastic pallets of different materials and raw materials also have large differences in cost. When choosing raw materials for plastic pallets, it is necessary to choose cost-effective raw materials according to the actual needs and uses, taking into account the cost factor.
In short, when choosing the material and raw materials of plastic pallets, you need to comprehensively consider factors such as the use environment, load requirements, service life and cost to choose the most suitable plastic pallets for your needs. At the same time, it is also necessary to pay attention to the selection of regular manufacturers and high-quality raw materials to ensure the quality and performance of plastic pallets.
