Microcellular plastics, otherwise known as microcellular foam, is a form of manufactured plastic, specially fabricated to contain billions of tiny bubbles less than 50 microns in size (typically from to micrometers).

This type of plastic is formed by dissolving gas under high pressure into various polymers, relying on "thermodynamic instability phenomena" to cause the uniform. Figure shows the microcellular foam injection molding process. And generally the microcellular foam injection molding proce ss is described as following fo ur steps.

Gibson May Introduction and synopsis. The word ‘cell’ derives from the Latin cella: a small compartment, an enclosed space. Our interest is in clusters of cells – to the Romans, cellarium, to us (less elegantly) cellular solids.

By this we mean an assembly of cells with solid edges or faces, packed together so that they fill space. This book presents the most important aspects of microcellular injection molding with applications for science and industry. The book includes: experimental rheology and pressure-volume-temperature (PVT) data for different gas materials at real injection molding conditions, new mathematical models, micrographs of rheological and thermodynamic phenomena, and the morphologies of microcellular Cited by: A book dedicated to material science, Biofoams: Science and Applications of Bio-Based Cellular and Porous Materials focuses on food technology, polymers and composites, biomedical, and chemical engineering, and examines how the principles used in the creation of cellular structures can be applied in modern : Hardcover.

Microcellular injection molding processes lead to reductions in weight, cycle times and molded-in stress, and improved dimensional stability. Thermoplastic foams can be produced with chemical foaming agents which release the foaming gas when the agent decomposes at a given temperature, or with Cellular and Microcellular Materials book foaming methods, which introduce the Cited by: 1.

Cellular ceramics are a specific class of porous materials which includes among others foams, honeycombs, connected fibers, robocast structures and assembled hollow spheres.
