Air Hoses – Specialised Gas Hoses Made from Various Materials

Air hoses fall into the category of gas hoses. Accordingly, when selecting the appropriate hose technology, attention must be paid to the chemical properties of the medium as well as to the respective operating temperature. RCT offers air hoses made from soft plastics/elastomers as well as from rigid plastics. Specifically, the following materials are available:

  • PUR (polyurethane, Vulkollan®)
  • PVC (polyvinyl chloride, THOMAVINYL)
  • PA (polyamide)
  • PE (polyethylene)
  • PP (polypropylene, Hostalen® PP)
  • MFA (modified fluoroalkoxy)
  • PVDF (polyvinylidene fluoride, Kynar®, Solef®)
  • PFA (perfluoroalkoxy, Hostaflon®)
  • PTFE (polytetrafluoroethylene, THOMAFLON)

Chemical Resistance of Air Hoses

FEP is resistant to petrol and other aliphatic hydrocarbons, benzene, xylene and other aromatic hydrocarbons, phenols, halogenated solvents, esters, ketones, ethylene oxide, formaldehyde, alkaline solutions, amines, pyridine as well as mineral acids and organic acids. Furthermore, FEP demonstrates resistance to hydrogen peroxide, hot water, UV radiation and radioactive radiation.

PFA (Perfluoroalkoxy / Chemfluor®)

PFA is characterised by excellent chemical resistance – including resistance to petrol, aliphatic and aromatic hydrocarbons such as benzene and xylene, phenols, halogenated solvents, esters, ketones, sodium hydroxide and potassium hydroxide. Ammonia solutions, aliphatic amines, aniline, pyridine, mineral acids, organic acids, hydrogen peroxide, hot water and UV radiation also do not affect PFA.
PFA is decomposed by free alkali metals.

MFA (Modified Fluoroalkoxy)

MFA is considered resistant to petrol and aliphatic hydrocarbons, benzene, xylene and aromatic hydrocarbons, phenols, halogenated solvents, esters, ketones, ethylene oxide, formaldehyde as well as to alkaline solutions, ammonia solutions, aniline and pyridine. MFA also demonstrates resistance when in contact with mineral acids, organic acids, hydrogen peroxide, hot water, UV radiation and radioactive radiation. MFA is decomposed by free alkali metals.

PVDF (Polyvinylidene Fluoride / Kynar® / Solef®)

PVDF is a fluoropolymer with high chemical resistance to petrol, aliphatic hydrocarbons, ammonia solutions, aliphatic amines, aniline, mineral acids, organic acids, hydrogen peroxide, hot water and UV radiation.

PTFE (Polytetrafluoroethylene / THOMAFLON)

PTFE offers universal resistance – particularly to lubricants, petrol, aliphatic and aromatic hydrocarbons, benzene, xylene, phenols, halogenated solvents, free halogens, esters, ketones, alkaline solutions, ammonia, mineral acids, organic acids as well as to hydrogen peroxide, ozone, other oxidising agents, hot water, steam and UV radiation.
PTFE is completely decomposed by free alkali metals and fluorine.

HDPE (High-Density Polyethylene)

HDPE is resistant to lubricants, oils, fats, petrol and aliphatic hydrocarbons. Alcohols, esters, ketones, organic acids, alkaline solutions, hot water as well as ammonia and amines also do not attack the material.

Air Hoses – Specialised Gas Hoses Made from Various Materials

Air hoses fall into the category of gas hoses. Accordingly, when selecting the appropriate hose technology, attention must be paid to the chemical properties of the medium as well as to the respective operating temperature. RCT offers air hoses made from soft plastics/elastomers as well as from rigid plastics. Specifically, the following materials are available:

  • PUR (polyurethane, Vulkollan®)
  • PVC (polyvinyl chloride, THOMAVINYL)
  • PA (polyamide)
  • PE (polyethylene)
