CO2 Gas Infusion

Patented Design Continuously Monitors and Updates the Level of Gas Entrainment

The Linden Industries CO2 Gas Infusion™ Blending Unit is commonly used to entrain gaseous CO2 in Polyurethane resulting in a reduction of chemical use, part weight and improved acoustical properties. Low levels of CO2 are used as an aid to improve tool wetability, mixing quality, material flow and eliminate surface defects in high density Polyurethanes.

CO2 aids in molding complex geometries and part configurations that would typically streak, run, or not fill; for example, vertical walls. CO2 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 homogeneous dissolution and distribution of CO2 into the Polyol component of the urethane formulation. This provides for minimum consumption of CO2.

The Linden unit can introduce gaseous, instead of liquid, CO2 and does not require sampling to regulate the level of CO2 in the PUR. A patented mechanism continuously monitors and updates the level of CO2, 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 CO2 tank pressures as low as 100 psi. In addition, CO2 is nonflammable, environmentally friendly, and an abundant natural resource.

The Gas Infusion unit can be provided as a component of new equipment or adapted to existing processing equipment as a stand-alone add-on system.
