Tightly lined PTFE sheets have the following characteristics:
1、 Good corrosion resistance
1. Resistance to chemical erosion
Tightly lined PTFE sheets have strong resistance to the vast majority of chemicals. Both strong acids (such as sulfuric acid, hydrochloric acid, nitric acid, etc.), strong bases (such as sodium hydroxide, potassium hydroxide, etc.), and various organic solvents (such as ethanol, acetone, benzene, etc.) are difficult to corrode. For example, in chemical production, it is common to come into contact with various corrosive media. Using tightly lined PTFE plates as equipment lining or pipeline materials can ensure long-term stable operation of equipment in harsh chemical environments.
This corrosion resistance makes tight lined PTFE sheets widely used in industries such as pharmaceuticals, electronics, and electroplating. In the pharmaceutical process, the production of drugs may involve various corrosive chemical reagents. Tightly lined PTFE plates can ensure that equipment is not corroded, thereby ensuring the quality and safety of drugs.
2. Resist oxidation
Teflon materials have high oxidation resistance and can maintain stable performance even in high temperature and strong oxidation environments. Even if exposed to air for a long time, it will not oxidize and deteriorate. For example, in fields such as high-temperature furnaces and heat treatment equipment, tightly lined PTFE sheets can be used as insulation and corrosion-resistant lining materials to withstand high temperatures and oxidative environments.
In some special industrial environments, such as the aerospace industry, the antioxidant properties of tightly lined PTFE sheets can also play an important role. Under harsh conditions such as high altitude and strong radiation, Teflon plates can protect equipment and components from oxidation and corrosion.
2、 Non sticky protrusion
1. Prevent adhesion
The surface of the tightly lined PTFE board has relatively low surface energy, and almost all substances are difficult to adhere to its surface. Whether it is a viscous liquid, powder, or solid particle, it can easily slide off its surface without adhesion. For example, in the food processing industry, equipment such as conveyor belts and baking trays made of tightly lined PTFE sheets can prevent food from sticking to the equipment, ensuring the quality and hygiene of the food.
In industries such as papermaking and printing, tightly lined PTFE sheets are also widely used in various components such as rollers and scrapers to prevent paper, ink, etc. from sticking to equipment, improving production efficiency and product quality.
2. Easy to clean
Due to its non adhesiveness, the tightly lined PTFE board is very easy to clean. Simply rinse with clean water or regular cleaning agents to easily remove dirt and residue from the surface. This feature makes tight lined PTFE sheets highly favored in industries such as healthcare and food that require high hygiene standards. For example, in hospital operating rooms, pharmaceutical workshops, and other places, equipment and instruments made of tightly lined PTFE sheets can be easily cleaned and disinfected to ensure the safety and hygiene of the medical environment.
3、 Good high temperature resistance
1. Endure high temperatures
Tightly lined PTFE sheets can be used continuously at temperatures up to 260 ℃, and can even withstand higher temperatures in a short period of time. This high temperature resistance makes PTFE sheets have a wide range of application prospects in the high-temperature industrial field. For example, in industries such as plastic processing and rubber vulcanization, tightly lined PTFE sheets can be used as lining materials for molds, heat exchangers, and other equipment to withstand the thermal impact during high-temperature processing.
In the aerospace industry, tightly lined PTFE sheets can also be used to manufacture high-temperature resistant seals, insulation materials, and other components, meeting the requirements for use in extreme high-temperature environments.
2. Good dimensional stability
In high temperature environments, the dimensional stability of tightly lined PTFE sheets is very good, and there will be no significant expansion or contraction due to temperature changes. This feature gives Teflon plates great advantages in the manufacturing and installation of high-temperature equipment, ensuring the accuracy and sealing of the equipment. For example, in fields such as high-temperature furnaces and heat treatment equipment, tightly lined PTFE sheets can be used as lining materials to ensure the normal operation of equipment at high temperatures, while not affecting its performance due to size changes.
4、 Good insulation performance
1. High resistance
Tightly lined PTFE board has relatively high resistance and is an excellent insulation material. It can effectively prevent the passage of current and avoid faults such as short circuits and leakage in electrical equipment. For example, in the electronics and electrical industries, tightly lined PTFE sheets can be used as insulation layers for wires and cables, substrates for circuit boards, etc., to ensure the safe operation of electrical equipment.
In some special environments, such as harsh conditions such as humidity and corrosion, the insulation performance of tightly lined PTFE plates can still remain stable, providing reliable protection for electrical equipment.
2. Strong arc resistance
Teflon material has strong arc resistance and can withstand arc impact under high voltage without being damaged. This characteristic has led to the widespread use of tightly lined PTFE plates in high-voltage electrical equipment. For example, in high-voltage switchgear, transformers and other equipment, tightly lined PTFE plates can be used as insulation components to improve the safety and reliability of the equipment.
5、 Reliable mechanical performance
1. High strength
Although the tightly lined PTFE board has a soft texture, it has high strength and toughness. Under certain pressure and tensile forces, PTFE sheets will not easily break or be damaged. For example, in chemical pipelines, containers and other equipment, tightly lined PTFE plates can withstand the pressure of internal media and external mechanical impacts, ensuring the safe operation of the equipment.
In some equipment that requires frequent disassembly and installation, the high strength and toughness of the tightly lined PTFE board can also ensure that it will not be damaged during repeated use, extending the service life of the equipment.
2. Good wear resistance
Teflon material has good wear resistance, and the tightly lined PTFE plate is not easily worn on the surface when rubbed against other objects. This feature gives Teflon plates a significant advantage in situations that require frequent friction. For example, in mechanical seals, sliding bearings, and other components, tightly lined PTFE plates can be used as friction pair materials to reduce wear and improve the service life of equipment.
6、 Environmentally friendly and non-toxic
1. Safe and reliable
Tightly lined PTFE board is a non-toxic and odorless material that poses no harm to human health or the environment. In industries such as food and healthcare, the use of tightly lined PTFE sheets can ensure product safety and hygiene. For example, in the fields of food processing equipment, medical devices, etc., the environmentally friendly and non-toxic characteristics of tightly lined PTFE sheets have been widely recognized.
Teflon board does not produce any harmful substances during production and use, meeting environmental requirements. This has made tight lined PTFE sheets increasingly valued in modern industry and become a green and environmentally friendly material choice.
2. Recyclable and reusable
After the end of its service life, the tightly lined PTFE board can be recycled and reused. Teflon materials have good processability and can be processed into other products, reducing resource waste and environmental pollution. For example, recycled PTFE sheets can be used to manufacture some low demand plastic products, building materials, etc.
