Silicone tubing has become a popular choice for applications that require resistance to heat, έλαιο, chemicals and solvents. Silicone’s versatility has led to numerous uses for heat resistant silicone tubing in industries like automotive, θαλάσσια, αεροδιαστημική, healthcare and more.
Properties Of Silicone Tubing
Silicone tubing is made from a flexible silicone polymer that offers several advantages over traditional rubber and plastic tubing:
- Θερμική αντίσταση – Silicone can withstand continuous temperatures from -80°F to 500°F, making it suitable for high temperature applications.
- Αντοχή σε λάδια και χημικά – Silicone is resistant to oils, γράσο, βενζίνη, solvents and many chemicals. It does not absorb fluids like rubber tubing.
- Ευκαμψία – Silicone remains flexible over a wide temperature range, retaining more than 200% elongation.
- Αντοχή στην υπεριώδη ακτινοβολία και στο όζον – Silicone can withstand UV exposure and ozone exposure better than rubber.
- Non-permeable – Silicone tubing does not allow fluids to permeate through the material.
- Μεγάλη διάρκεια ζωής – Properly installed silicone tubing can last up to 20 χρόνια.
Applications For Heat Resistant Silicone Tubing
Some common uses for heat and oil resistant silicone hose include:
- Αυτοκίνητο – Replacing aging vacuum and coolant hoses. Used for air intake, charge air cooler and fuel lines.
- θαλάσσια – Replacing rubber and plastic bilge pump hoses, coolant hoses and fuel lines.
- Βιομηχανικός – Transferring heated oils, lubricants and hydraulic fluids. Used as gaskets and O-rings.
- Lab equipment – Transporting corrosive chemicals, heated reagents and compressed gases.
- Commercial kitchens – Carrying boiling water, έλαιο, gases and other fluids.
- HVAC – Replacing rubber ducting and duct connections.
- Pools and spas – Carrying heated water and chemically treated water.
Silicone Tubing Sizes And Specifications
- Silicone tubing is available in a wide range of sizes from 1/32″ outside diameter to 12″ outside diameter, with inner diameters from 0.1 mm to 127 mm.
- Wall thicknesses range from very thin (.012″ – .030″) for uses requiring flexibility to thicker (.080″ – .250″) for higher pressure and temperature requirements. Silicone tubing is rated for continuous use between -80°F to 500°F and up to 3000 PSI pressure depending on wall thickness.
- Specialty silicone tubing formulations are available with additives for increased heat, cold or oil resistance. Reinforced silicone tubing contains fibers or braids for extra strength.
