Supercritical CO₂ Physical Foaming Agent

Product features:

Unlike chemical foaming agents that release toxic byproducts during curing, this physical foaming agent only uses CO₂, which is completely harmless and leaves no residual substances after foaming, making it ideal for food contact applications. It produces extremely uniform foam cells with a narrow size distribution, improving the structural stability and surface quality of foamed plastic products. The foaming process can be precisely controlled by adjusting pressure and temperature, allowing manufacturers to customize foam density and cell structure according to product requirements. It also reduces material usage by up to 30% compared to solid plastic products while maintaining excellent mechanical performance, helping producers cut costs and improve sustainability.

Product specifications:

Purity of CO₂: 99.99%, Operating temperature range: 31.1℃ to 100℃, Operating pressure range: 7.38-10 MPa, Recommended dosage: 2-5% of polymer raw material mass, Average cell size: 0.1-0.5mm, Foam density range: 0.3-0.8g/cm³, Compatibility: Suitable for most thermoplastic polymers, Certification: FDA 21 CFR §177.1520, EU Regulation 10/2011, Storage condition: Low-temperature liquid storage tank or ISO tank containers, Shelf life: Indefinite when stored properly

Product application:

Food packaging containers (such as disposable lunch boxes, yogurt cups), automotive interior trim parts, electronic device packaging buffers, consumer goods housing, sports equipment components, and medical device packaging. It is widely used in the plastics processing industry to produce lightweight, eco-friendly foamed plastic products that meet strict food safety and environmental protection standards.
