Liquid CO2 technology – CarDio®

CarDio® is our patented process for producing low-density polyurethane foams using liquid carbon dioxide (CO2) as the blowing agent. This innovative solution offers a cleaner, safer, and more sustainable alternative to harmful chemicals like methylene chloride, making it ideal for companies looking for an eco-friendly manufacturing method or to comply with strict environmental regulations.

Liquid CO2 technology
CarDio® key features

Tailored design

ensures optimal performance

Compatible with

all foam plants

Enables trouble-free

high-viscosity production

Designed to perfection

The CarDio® system is expertly engineered to deliver consistent, high-quality foam production with minimal maintenance. Its advanced design features an innovative airless gatebar and elongated slot, ensuring full-width foam laydown while preventing blockages even when using fillers or high-viscosity materials.

Available as both “Direct” and “Indirect” configurations, it seamlessly integrates with new or existing foaming equipment, offering unmatched flexibility for diverse production needs. This system’s ability to process a wide range of materials ensures optimal performance and reliability for long production runs without problem.

CarDio® Gatebar

The CarDio® Gatebar plays a vital role in ensuring precise and controlled foam expansion. Liquid CO₂ expands immediately and evenly upon exiting the Gatebar, creating a homogeneous foam froth free from bubbles, voids, or pinholes.

This froth rises uniformly to the desired block height within seconds, ensuring a flat top profile that minimizes waste and maximizes chemical conversion into usable foam. Thanks to its optimized slot dimensions and shape, the Gatebar allows for extremely long production runs without the risk of buildup, even when using high-viscosity materials or fillers.

Alternative technologies are often limited in flexibility and reliability, suffering with frequent blockages when handling demanding formulations leading to shut down and short production runs. The CarDio® Gatebar’s advanced engineering sets a new benchmark for foam expansion, precision and efficiency with optimum foam laydown distribution.
