What are factory customized high-quality PTFE rods?
PTFE rod, also known as polytetrafluoroethylene rod, is a polymer material rod made by polymerizing tetrafluoroethylene as a monomer.
Advantages of factory customized high-quality PTFE rods
Extremely low friction coefficient. PTFE rod is one of the materials with the lowest friction coefficient among solid materials, with a smooth surface like wax. When applied in mechanical moving parts, it can greatly reduce friction.
Good resistance to chemical penetration. Its tight molecular structure makes it difficult for chemicals to penetrate. This characteristic is particularly important for equipment components used in complex chemical environments.
Limitations of factory customized high-quality PTFE rods
Relatively low mechanical strength. The tensile and compressive strength of PTFE rods are lower than many metal materials and some engineering plastics. When subjected to high tensile or compressive forces, deformation is prone to occur.
High cost. The production cost of PTFE rods is relatively high, mainly due to its complex synthesis process and high raw material costs. In some cost sensitive application scenarios, higher prices may limit their use.
The main function of factory customized high-quality PTFE rods
PTFE rods mainly have functions such as sealing, wear resistance, friction reduction, insulation, and chemical corrosion resistance. It can be used to make sealing gaskets, mechanical moving parts, insulation layers for wires and cables, and chemical equipment linings, playing an important role in multiple fields.
The working principle of factory customized high-quality PTFE rods
The sealing of PTFE rods relies on low surface energy molecular structure and elastic deformation; Wear resistance and friction reduction are the molecular chain characteristics and transfer film effects; Insulation restricts electrons and impedes heat transfer due to its molecular structure; Chemical corrosion resistance is achieved through stable carbon fluorine bonds and surface protection.
There are various types of factory customized high-quality PTFE rods , how to choose the one that suits you
一、Consider the main requirements of the application scenario
1.Insulation demand scenario. In terms of insulation applications, whether it is electrical insulation or thermal insulation, the selection should be based on specific voltage, frequency, temperature range, etc. For high-voltage and high-frequency electrical equipment, it is important to ensure that PTFE rods have sufficient electrical insulation strength, purity, and internal structural uniformity.
2.Chemical corrosion resistance requirement scenario. When the usage environment involves chemical corrosion, it is necessary to be clear about the types of chemicals in contact. If working in a complex chemical environment, such as a certain link in a chemical production process, it is necessary to choose PTFE rods that can withstand all possible chemical substances that may come into contact, while considering their long-term corrosion resistance and chemical permeability.
二、Consider matching physical and mechanical properties
1.Size and shape requirements. Select PTFE rods of appropriate size and shape based on the actual installation space and equipment shape. Some devices may require customized PTFE rods with special shapes, such as irregularly shaped seals or mechanical components.
2.Strength and hardness characteristics. For applications that require a certain amount of pressure or friction, such as serving as support or friction components in some mechanical structures, the strength and hardness of PTFE rods should be considered. If the strength is not sufficient, it may deform under pressure; Inappropriate hardness may affect its wear resistance and sealing performance.
三、Consider cost and lifespan factors
1.Cost benefit analysis. There are significant price differences among PTFE rods of different brands, specifications, and quality levels. On the premise of meeting application requirements, cost should be comprehensively considered. We cannot choose PTFE rods that do not meet the requirements just because they are cheap, as it may lead to frequent replacement and increase long-term costs.
2.Estimation of service life. Based on the working conditions in the application scenario, such as temperature, pressure, friction frequency, and degree of chemical contact, estimate the service life of PTFE rods. Try to choose PTFE rods with long service life, which can reduce the frequency of equipment maintenance and component replacement, and improve the operational efficiency of the equipment.
