Ptfe capillaries are extremely fine, forming a set of independent general specifications according to its use. Also may according to the different need, makes the black capillary tube, the white capillary tube, the yellow capillary tube, the red capillary tube and the transparent capillary tube and so on, generally is blue or the black reel packing.
- Ptfe capillary molding process
Ptfe capillary tube is a special pipe made by drying, high temperature sintering and finalizing after mixing ptfe dispersion resin and propellant, and then subjected to certain shearing force in the mouth mold with cone Angle.

- Main characteristics of ptfe capillary tube
(1). Very low friction coefficient: its friction coefficient is generally only 0.04, is a very excellent self-lubricating material, and the friction coefficient does not change with the temperature.
(2). High chemical stability: it can withstand all strong acids, including aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acid, strong alkali, strong oxidant, reducing agent and various organic solvents. Very suitable for high purity chemical feeding.
(3). Good anti – viscosity, tube wall is not easy to adhere to colloid and chemicals.
(4). Excellent electrical insulation performance: PTFE is a highly nonpolar material with good dielectric properties and great resistance. Its dielectric constant is about 2.0, which is the smallest among all electrical insulation products.
(5). Flexible and flexible.
(6). Good anti – viscosity, tube wall is not easy to adhere to colloid and chemicals.
(7). Part of the tube transparency, easy to observe the internal fluid status.
3. Use of ptfe capillary tube
It is widely used in chemical industry, chlor-alkali industry, machinery, automobile, electric heating pipe, pulp, steam, compressed gas, heat exchanger, coating, textile, pharmaceutical, medicine, bicycle industry, coffee machine and other industries, mainly used as catheter.
In addition can also use fep (PVF and six f propylene copolymer) made of transparent tube, its basic retain the performance of ptfe, such as: excellent high and low temperature resistance, chemical stability, electrical insulation, prominent not sticky and high mechanical strength, only on the high temperature limit 50 ℃ lower than the ptfe. But it is more flexible and transparent than ptfe, making it easier to see what’s going on inside as it transports liquids and gases.
