Rotomoldable Acetals for Hydraulic Fluids Tanks

Darin Grinsteinner

Celanese

In the last few years, new Copolymer Acetals have shown the ability to be a 1-layer solution for Fuel tanks due to its low fuel permeation and good mechanical property balance. These some materials have recently been shown to also work well for Hydraulic fluid tanks. These new copolymer acetals provide good thermal stability, low swell and low permeation. This gives OEM and molders an option to polyamides that process at lower temperatures and have excellent mold release properties.
