PTFE Pan Head Phillips Screws - The characteristics of PTFE are mainly in the following aspects:
1. High-temperature resistance: using working temperature up to 260 ℃.
2. Low-temperature resistance: good mechanical toughness, even if the temperature drops to -196 ℃, can maintain 5% elongation.
3. Non-toxic: physiologically inert, such as artificial blood vessels and organs, for long-term implantation without adverse reactions.
4. Mechanical properties, non-adhesion: smooth and abnormal. Even ice can not compare to it. It is the minor surface tension in solid materials and does not adhere to any substance. Its coefficient of friction is minimal, only 1/5 of polyethylene, an essential feature of the perfluorocarbon surface. And because the fluorine-carbon chain intermolecular force is shallow, PTFE is non-stick.
5. Excellent insulating properties: a paper-thin film layer is enough to resist 1500V high voltage.
6. Chemical resistance and weather resistance: Unlike molten alkali metals, PTFE is not subject to corrosion by almost any chemical reagent. For example, its weight and performance are unchanged in concentrated sulfuric acid, nitric acid, hydrochloric acid, and even when boiled in aqua regia. It is almost insoluble in all solvents and only slightly soluble in all alkanes at 300 ℃ or more (about 0.1g / 100g).
7. Excellent weather resistance: non-absorbent, non-combustible, extremely stable to oxygen, ultraviolet radiation, plastic Pan Head Phillips Screws in the best aging life.
8. Electrical properties: PTFE Pan Head Phillips Screws in a wide frequency range of dielectric constant and dielectric loss are shallow, and breakdown voltage, volume resistivity, and arc resistance are high.
9. Radiation resistance: PTFE Pan Head Phillips Screws have poor radiation resistance (104 rads), degradation caused by high-energy radiation, and the electrical and mechanical properties of the polymer are significantly reduced.
Product Specification
PTFE Polytetrafluoroethylene Pan Head Phillips Screws Application Industry Solutions
PTFE, the full name of polytetrafluoroethylene, is a polymer material with excellent chemical resistance, high temperature resistance, low coefficient of friction, and insulating properties; PTFE material with corrosion resistance, aging resistance, low coefficient of friction and non-sticky, wide range of temperature resistance, elasticity, and sound characteristics make it very suitable for the manufacture of corrosion-resistant requirements of the seals, the use of the temperature is higher than 100 ° C. Sealing the slotted flanges of machines, heat exchangers, high-pressure vessels, large-diameter vessels, valves, and pumps, such as machines, heat exchangers, high-pressure containers, large-diameter containers, valves, pumps, seals for grooved flanges, glass reaction pots, flat flanges, seals for large-diameter flanges, shafts, piston rods, valve rods, worm gear pumps, tie rods, and so on. Due to its unique properties, PTFE Pan Head Phillips Screws are used in many industries.
1. Application in the chemical industry: PTFE can be used for a long time under the harsh environment of strong acids, strong alkalis, organic solvents, and so on because of its corrosion-resistant performance.
