Plastic screws are a type of fastener made of polymer materials and are widely used in various industrial, electronic, medical and consumer product fields. Compared with traditional metal screws, plastic screws have the advantages of light weight, corrosion resistance, good insulation and low cost. There are many types of plastic screws, the most common ones are polyamide (PA, nylon), polycarbonate (PC), polypropylene (PP), polyoxymethylene (POM, Saigang) and polytetrafluoroethylene (PTFE). Each material has its own unique physical and chemical properties and is suitable for different application scenarios. PTFE screws are suitable for occasions that require corrosion resistance, high temperature resistance and low friction, but it should be noted that their mechanical strength is relatively low.

● Lightweight: The density of plastic screws is much lower than that of metal screws, which can significantly reduce the weight of the overall structure and is particularly suitable for weight-sensitive applications such as aerospace and automotive industries.
● Corrosion resistance: Plastic screws have excellent corrosion resistance to chemicals such as acids, alkalis, and salts, and are suitable for harsh environments such as chemical and marine environments.
● Good insulation: Plastic screws have good electrical insulation properties and are suitable for electronic and electrical equipment to prevent current leakage and short circuits.
● Low friction coefficient: Certain plastic materials, such as PTFE, have extremely low friction coefficients and are suitable for applications that require reduced friction and wear.
● Low cost: The production cost of plastic screws is generally lower than that of metal screws, and they are easy to mass produce and suitable for large-scale applications.
● Electronics and electrical: Plastic screws are widely used in electronic equipment, circuit boards, terminal blocks, etc., providing insulation protection and lightweight solutions.
● Medical equipment: Plastic screws are increasingly used in medical equipment, such as surgical instruments, diagnostic equipment, etc., due to their non-toxic, corrosion-resistant and easy-to-sterilize properties.
● Automotive industry: Plastic screws are used in automotive interiors, electronic control systems, sensors, etc. to reduce vehicle weight and improve fuel efficiency.
● Chemical industry: The application of plastic screws in chemical equipment, pipes, storage tanks, etc. can effectively resist chemical corrosion and extend the service life of equipment.
● Consumer goods: The application of plastic screws in consumer goods such as household appliances, toys, furniture, etc. provides beautiful, lightweight and durable solutions.
Polytetrafluoroethylene (PTFE), commonly known as “Teflon”, is a high-performance fluoropolymer material with the following significant properties:
● Extremely low friction coefficient: PTFE has the lowest friction coefficient of all plastics, about 0.04, which makes PTFE screws perform well in applications that need to reduce friction and wear.
● Excellent chemical resistance: PTFE is not corroded by almost all chemicals, including strong acids, strong alkalis and organic solvents, and is suitable for extreme chemical environments.
● Wide temperature range: PTFE can maintain stable physical and chemical properties in the temperature range of -200°C to +260°C, suitable for high and low temperature environments.
● Excellent electrical insulation: PTFE has extremely high resistivity and extremely low dielectric constant, suitable for high-frequency and high-voltage electrical applications.
● Non-stick: The PTFE surface has extremely low surface energy and hardly adheres to any substance, suitable for applications that require anti-stick.
● Low friction and wear resistance: The extremely low friction coefficient of PTFE screws makes it perform well in applications that require frequent rotation or sliding, such as bearings, guides and seals.
● Chemical corrosion resistance: PTFE screws can resist corrosion from almost all chemicals and are suitable for industries such as chemical, pharmaceutical and food processing.
● High temperature stability: PTFE screws can still maintain their mechanical properties and dimensional stability in high temperature environments, suitable for high temperature equipment and processes.
● Electrical insulation: PTFE screws provide excellent insulation protection in electrical and electronic equipment to prevent current leakage and short circuits.
● Non-sticky: The surface of PTFE screws is not easy to adhere to dirt and impurities, easy to clean and maintain, and suitable for food and medical equipment.
● Chemical equipment: The application of PTFE screws in chemical reactors, pipes, valves and pumps can effectively resist chemical corrosion and extend the service life of equipment.
● Food processing: The application of PTFE screws in food processing equipment meets food safety standards due to its non-toxic, corrosion-resistant and easy-to-clean characteristics.
● Medical equipment: The application of PTFE screws in surgical instruments, diagnostic equipment and implants provides biocompatibility and chemical resistance.
● Electronics and electrical: The application of PTFE screws in high-frequency and high-voltage electrical equipment provides excellent electrical insulation performance and high-temperature stability.
● Aerospace: The application of PTFE screws in aerospace equipment improves equipment performance and reliability due to its lightweight, high-temperature and chemical corrosion resistance.
