一、What is PTFE tube?
PTFE tube is a fluoroplastic tube made by mixing, pressing, cold extrusion, sintering and shaping polytetrafluoroethylene material. PTFE is the earliest discovered fluoroplastic, also known as Polytetrafluoroethylene in English. It is a polymer composed of four fluorine atoms and two carbon atoms, and has high temperature resistance, strong acid and alkali resistance, and other properties. PTFE pipe is also known as PTFE pipe, PTFE pipe, PTFE pipe, F4 pipe, PTFE pipe, plastic king pipe.
二、 What are the characteristics of PTFE tubes?
When the plastic molecular structure contains carbon chains with hydrogen atoms, such as in the structure of polytetrafluoroethylene (PTFE), hydrogen atoms are replaced by fluorine atoms. This greatly changes the properties of the material, and like other fluoroplastics, PTFE pipes have special characteristics:
1、High working temperature, with a temperature resistance of up to 260 ℃
2、Non stick characteristic
3、 Low friction coefficient
4、 Extremely strong resistance to chemicals and solvents, even "aqua regia" does not react with PTFE.
5、 Extremely high resistance, can be used as high-voltage insulation material
6、 Resistant to weather, UV rays, and corrosion
7、 Inert, non-toxic, and biocompatible
三、 Advantages and disadvantages of PTFE pipes
1 Advantages of PTFE pipes:
• Discounted price: Performance ratio. Compared to other fluoroplastic pipes, PTFE pipes have a price advantage.
• Working temperature+260 ° C - this is the highest working temperature among fluoroplastics
• Resistant to almost all chemicals
• Low friction surface - even geckos can slide on PTFE
• Extremely high resistance
• Translucent color
2. Disadvantages of PTFE tube:
• Does not melt during processing, difficult to process
• Large mold customization requirements
• PTFE tube cannot be welded
四、 Where is PTFE applied?
With its excellent performance, PTFE pipes can be used in harsh environments, making them widely used. PTFE is highly suitable for food and beverage production, from cooking equipment to food coverings, conveyor rollers, temperature sensor housings, and non stick surface coatings. In the chemical industry, PTFE can be used to manufacture various products, from gaskets to container liners and chemical tanks. PTFE is also widely used in high-temperature environments, from fire protection to terminal insulation for heating elements and jet engines, ultraviolet lamps, and aircraft exterior accessories. PTFE material is an ideal choice for medical applications such as catheters, biological containers, syringes, and sutures. This unique fluorinated polymer is also an ideal choice for electrical insulation and electronic component protection. Fluorinated polymers are also woven into our daily lives in hundreds of ways. At home, non stick pans are made of PTFE, and most razors come with PTFE based anti friction coatings. Electrical equipment from smartphones to laptops also include PTFE insulation components.
