Supercritical CO2 Foaming Technology


Nov . 2023
Supercritical CO2 foaming technology is an environmentally friendly method that can reduce waste and harm to the environment to a great extent.

With the gradual improvement of environmental awareness, more and more companies are beginning to pay attention to the issue of sustainable development and explore more environmentally friendly production methods. Supercritical CO2 foaming technology is an environmentally friendly method that can reduce waste and harm to the environment to a great extent.

Supercritical CO2 foaming is a technology that uses supercritical fluids to foam plastics. Supercritical fluid is a high-viscosity, high-density substance with strong permeability and lubricity. Put the plastic sample into supercritical CO2, and then quickly cool down and the pressure will drop suddenly, causing the CO2 to be quickly released from the plastic, and the plastic sample will form small bubbles, thereby achieving the foaming effect. During this process, CO2 will evaporate quickly from the medium without causing any pollution to the environment in the process.

Supercritical CO2 foaming can be used not only to produce plastic products, but also to produce foam materials and various polymer materials. Supercritical CO2 foaming technology can reduce production waste and CO2 emissions, while also reducing production costs.

Traditional foaming technology usually uses Freon, a toxic substance. This substance will be released during the foaming process, which is very harmful to the environment and human health. Supercritical CO2 foaming technology is a new environmentally friendly technology that can reduce or even completely eliminate the use of toxic substances, thereby minimizing environmental pollution and the impact on people's health.

In the future, as people gain a deeper understanding of environmental protection issues, supercritical CO2 foaming technology will be more widely used. Through this technology, we can produce more environmentally friendly and sustainable products and reduce environmental harm during the production process, which is beneficial to human health and future sustainable development.

In short, supercritical CO2 foaming technology is an innovative environmentally friendly technology that makes our production more environmentally friendly and sustainable. Although there are still some problems that need to be solved, I believe that with the continuous development and improvement of technology, we will see more people begin to adopt this technology, so that environmental protection and industrial development are no longer two conflicting goals.
