N2-Nitrogen or Dry Air Gas Infusion

The Latest in Nucleation Technology

Patented Design Continuously Monitors and Updates the Level of Gas Entrainment.

The Linden N2 or Dry Air Gas Infusion™ Blending Unit is commonly used to nucleate Polyurethane resulting in a reduction of chemical use, part weight, and improved insulation properties. Low levels of N2 or Dry Air are used as a nucleation aid to improve tool wetability, mixing quality, material flow and eliminate surface defects in Polyurethanes.

N2 or Dry Air aids in molding complex geometries and part configurations that would typically streak, run, or not fill; for example, vertical walls. N2 or Dry Air is also used to improve foam characteristics, reduce urea formation and is suitable for all types of metering machines and mixing heads.

The Linden Gas Infusion Blending Unit provides a homogenous dissolution and distribution of N2 or Dry Air into the Polyol component of the urethane formulation. This provides for minimum consumption of N2 or Dry Air.

The Linden unit can introduce gaseous, instead of liquid, N2 or Dry Air and does not require sampling to regulate the level of N2 or Dry Air in the PUR and PIR. A Coriolis effect mechanism continuously monitors and updates the level of N2 or Dry Air, which is more accurate than periodic sampling.

Introduced as a gas, compared to liquid systems, processing is possible with day tank blanket pressures are as low as 40 psi and N2 tank pressures under 100 psi. In addition, N2 or Dry Air are nonflammable, environmentally friendly, and an abundant natural resource.
