A container of beautifully packed layflat hose will be delivered
In the last piece, we learned 2 materials for industrial rubber hoses. While this time, let’s let me show you some other materials.
Fluoropolymer
Such inner tubing has a wide range of apps. While it rapidly replaces silicone as the material choice for hygienic use. PTFE, PFA and FEP are the 3 common fluoropolymers. They have a wide temp range from -53℃ to 230℃.
This is the most chemical resistant inner tube on the market. Besides, it does not age and stick. In addition, it is easy to clean and can withstand repeated steam cleaning. Like metal inner tube, it also have lower absorption rate.
New tech have allowed PTFE hose to be as flexible as silicone hose. Bonding tech can add layers of fiberglass braid to be more flexible. This process avoids the glue entering into the inner tube wall. Then it can avoid the pollution.
However, fluids may develop static as they pass through the inner tube. Then this can cause static sparks which can damage the rubber hose and create a safety hazard. In order to deal with such risk, you should fill carbon black into the inner tube. Because carbon allows the charge to move safely to the outlet.
Thermoplastic for industrial rubber hoses
Thermoplastic hose or nylon inner tube often serve for hydraulic apps. While the typical thermoplastic hydraulic hose includes SAE 100 R7, SAE 100 R8 and R14. Because this type of inner tube can withstand high pressure. Besides, it can work at -40℃ to 93℃. The hose is up to one inch in diameter. Nylon tube is an economical and general purpose hose. Because it has much better pressure resistance than flexible metal hose.
However, it has a higher permeability rate due to its soft, permeable material structure. Besides, its work temp range is not as wide as other materials.
