Technical details

- The ducting produced with this thermoplastic may suffer a slight swelling if used for transporting aromatic hydrocarbon gases, chlorine, hot water or steam.

- Insolubility of water, ether or alcohol.

- Step wire narrower than in Vena®TechniPUR type. Higher vacuum resistance.

Properties

- High abrasion resistant, polyurethane is ten times stronger than PVC.

- Resistance to aging and therefore durable and high flexibility.

- High stability against hydrolysis (decomposition of materials by water).

- Stability against oil, greases and aliphatic hydrocarbons.
