Low permeability. Applied to carrying aggressive liquid or gases in hostile environments.
As fuel permeation resistance regulations around the world continue to become more stringent, hose designers can count on our products to help meet evolving fuel emission standards. Fuel line hoses are typically multilayered structures, which often contain a fluoropolymer such as fluoroelastomer and THV for evaporative emission reduction. The requirements for fuel hoses can include: low permeation rate, flexibility, resistance against fuels and biofuels, strong bonding properties, long-term durability and good low temperature flex.
3M™ Dyneon™ Fluoropolymers are widely used in fuel line hose applications because of their excellent permeation and chemical resistance. They have excellent performance when exposed to high temperatures, alternative fuels (FAM B / RME) and gasoline with an increasing ethanol or methanol share.
Tubing made from 3M™ Dyneon™ Fluoropolymers is widely used in the chemical and associated industries because of its excellent performance in extreme environments, including high purity applications. These conditions could include exposure to a broad chemical and a wide service temperature range. In addition, tubing may need to meet sanitary, FDA, pharmaceutical or similar approvals.
If you are working with petroleum, synthetic or water-based hydraulic fluids in material handling equipment and mechanical systems, there's a role for 3M™ Dyneon™ PTFE. Used as the inner layer in the construction of multi-layer hoses, it shows excellent temperature, chemical and permeation resistance at elevated pressures. In addition, the broad chemical compatibility and low surface energy of Dyneon PTFE can support long-lasting, very high flow rates by resisting sedimentation on the hose surface.
