CREATING LIGHTWEIGHT, COST-EFFICIENT PLASTICS WITH A SOLID-STATE MICROCELLULAR PROCESS

MicroGREEN’s exclusive technology creates a microcellular structure in common thermoplastics which can then be thermoformed into deep-draw shapes. In place of a molten plastic-based process such as extrusion, this new method starts with solid plastic.

Microscopic view of PET plastic before and after expansion process.

• Materials: This process applies to most common thermoplastic polymers, including the new biopolymers (PLA).
• Density Reductions: This very controllable process achieves density reductions of up to 90% (i.e., 10% of the density of solid plastic) across the list of common thermoplastics.
• Integral Skin: The finished plastics contain microscopic bubbles (microcells) and retain the look and feel of solid plastics. This is due to the creation of an integral skin over the cellular core structure. You get the beneficial properties of layered materials without the added steps of lamination or co-extrusion. See video clip below.
• Crystallization: MicroGREEN’s technology creates high temperature resistance (up to 400°F for PET) in products starting with a range of semi-crystalline polymers. Crystallization is achieved without any additives.
• Thermoformable: This technology enables deep-draw thermoforming of expanded thermoplastics with void fractions greater than 80%.
• Benign Gases: This eco-friendly technology uses benign gases such as carbon dioxide (CO2) and nitrogen (N2).
• Common Equipment: The unique production configuration utilizes equipment that is currently available in the marketplace
• Production Rates: Thermoforming throughput and cycle times are comparable to those of solid plastic counterparts.
