APPLICATIONS
Polymer processing shapes and molds plastics into products for packaging, automotive, electronics, and consumer goods industries. Carbon dioxide is used in supercritical fluid extrusion to create lightweight, foamed polymers. Nitrogen assists in gas-assisted injection molding, improving surface finish and reducing defects. Hydrogen is used in hydrogenation to enhance polymer flexibility and durability. These gases optimize polymer processing for high-quality, efficient production.

Polymer processing involves the conversion of raw polymer materials into finished products through various techniques such as extrusion, injection molding, blow molding, and thermoforming. Industrial gases play a crucial role in enhancing these processes.
Common industrial gases used in polymer processing include nitrogen (N₂), carbon dioxide (CO₂), and air. These gases are used for purposes such as purging, cooling, foaming, and improving process efficiency.
Nitrogen is used for purging to remove oxygen and moisture from the processing environment, preventing oxidation and degradation of polymers. It is also used in gas-assisted injection molding to improve part quality and reduce cycle times.
Carbon dioxide is used for foaming applications, where it acts as a blowing agent to create lightweight, porous polymer structures. It is also used in supercritical CO₂ extraction for polymer purification and in cooling processes to control temperatures.
Benefits include improved product quality, reduced defects, enhanced process efficiency, lower material and energy costs, and the ability to produce complex shapes and lightweight structures.
In polymer extrusion, gases like nitrogen and CO₂ are used for cooling and purging. They help in maintaining optimal temperatures, preventing oxidation, and ensuring the quality and consistency of extruded products.
Industrial gases help in controlling process parameters, reducing cycle times, minimizing waste, and enhancing product quality. They enable more precise and efficient processing techniques, leading to cost savings and higher productivity.
