What are manufacturers wholesale various PTFE sheets?
PTFE sheet is made of PTFE resin through polymerization reaction of tetrafluoroethylene monomer, and then processed through molding, extrusion and other molding processes.
Advantages of manufacturers wholesale various PTFE sheets
Super corrosion resistance. PTFE plates have extremely excellent corrosion resistance, and apart from a few strong oxidizing substances and certain alkali metals at high temperatures, they hardly react with any chemical substances.
Low friction characteristics. PTFE plate has an extremely low coefficient of friction and good self-lubricating properties. In mechanical moving parts, it can significantly reduce friction, minimize energy loss and component wear, improve equipment operating efficiency and service life, while also reducing maintenance frequency and costs.
Limitations of manufacturers wholesale various PTFE sheets
Low mechanical strength. PTFE plates have relatively low mechanical strength indicators such as tensile strength and compressive strength, and are not suitable for structural components that can withstand large external forces and high pressures.
High shrinkage rate during molding. PTFE plates have a large and uneven shrinkage rate during the molding process, which makes it difficult to control the size of the product and obtain high-precision products. Special measures need to be taken in mold design and molding processes.
The main function of manufacturers wholesale various PTFE sheets
PTFE board has functions such as corrosion resistance, insulation, friction reduction and wear resistance, sealing, anti sticking and weather resistance, and is widely used in fields such as chemical, electronic and electrical, mechanical, food and construction.
The working principle of manufacturers wholesale various PTFE sheets
PTFE plates work with a stable molecular structure composed of unique carbon fluorine bonds, which makes their chemical properties stable and resistant to strong acid-base corrosion; The low friction coefficient is due to the small intermolecular forces, achieving self-lubricating performance; High electrical insulation due to the difficulty of electron movement; The high and low temperature resistance is due to its regular structure and strong thermal stability, which plays a key role in multiple fields.
There are various types of manufacturers wholesale various PTFE sheets , how to choose the one that suits you
一、Usage environment
1.High temperature environment. If used in high-temperature ovens, heat treatment equipment, etc., PTFE plates that can withstand high temperatures should be selected. When working in an environment above 200 ℃ for a long time, modified PTFE sheets filled with glass fibers can be chosen to improve thermal stability and reduce deformation and creep at high temperatures.
2.Low temperature environment. In low-temperature environments such as freezers and polar operation equipment, it is necessary to ensure that PTFE plates do not become brittle at low temperatures, maintain good flexibility and mechanical properties. PTFE plates that have undergone low-temperature treatment processes can be selected, which can be used normally at temperatures of -50 ℃ or even lower.
二、Budget cost
1.Product price. There is a significant price difference for PTFE sheets of different types and specifications. Pure PTFE sheet has a relatively low price and is suitable for general applications that do not have particularly demanding performance requirements; The price of filled modified PTFE plates may increase due to the addition of special materials, but their performance is superior and suitable for occasions with high performance requirements.
2.Comprehensive cost. In addition to the purchase price, comprehensive costs such as installation and maintenance also need to be considered. For example, although some high-performance PTFE sheets are expensive, they have a long service life and low maintenance costs, which may result in higher cost-effectiveness in the long run.
三、Processing technology
1.Cutting processing. If cutting processing is required to produce various shapes of parts, PTFE plates with moderate hardness and less likely to produce chips and broken edges during cutting should be selected. For cutting with high precision requirements, it is also necessary to consider the dimensional stability of the material to avoid dimensional changes caused by stress release after cutting.
2.Welding processing. Used for welding large containers, pipelines, etc., PTFE plates with good welding performance should be selected, and the welding parts should achieve high strength and sealing. You can select products suitable for welding equipment and processes by viewing the welding parameters and process specifications of the materials.
四、Performance requirements
1.High strength requirements. Used for manufacturing mechanical components that can withstand high pressure and load, such as high-pressure seals, bearings, etc., PTFE plates filled with reinforcing materials such as carbon fiber and graphite should be selected to improve their compressive strength and wear resistance.
2.Flexibility requirements. For sealing gaskets for pipeline connections, flexible insulation sleeves, etc., PTFE plates need to have good flexibility and elasticity to maintain sealing or insulation performance under different working conditions.
