The Chemistry of Chemical Foaming Agents | Phoenix Plastics
网页2023年7月26日 · In plastics manufacturing, chemical foaming agents come in two primary varieties: physical foaming agents and chemical foaming agents. Both agents are designed to increase the volume of plastics, making them easier to mold into complex shapes. Here is what you need to know about chemical foaming agents.
How to Improve Foaming Process in Polymers? - SpecialChem
网页2024年7月22日 · Polymer foaming is a process that involves introducing gas into a polymer matrix to create a cellular structure within the material. In general, the foaming process involves four steps as follows: Dissolution of foaming agent: Creation of a homogeneous polymer/gas mixture. Bubble nucleation: Acts as the center for bubble growth after a …
Recent Trends of Foaming in Polymer Processing: A Review - MDPI
网页2019年6月1日 · Compared with the regular foaming process using a chemical blowing agent, microcellular foaming with a physical blowing agent can produce polymer foams with much finer cells, which have highly specific properties, including good thermal stability, excellent sound absorption properties, and a low thermal conductivity and …
Thermoplastic Foams: Processing, Manufacturing, and Characterization
网页2017年5月24日 · Thermoplastic foams are generally obtained by batch foaming, foam extrusion, and foam injection foaming. Batch foaming is cheaper than the others due to simple equipment, but in each method, the main aim is to promote cell morphology by providing small cell in diameter and high cell density in the polymer matrix.

Foaming Agent - an overview | ScienceDirect Topics
网页Most generally, a foaming agent (FA) is a material that, in the vapour phase, expands a polymer melt upon reduction in pressure, and as a result a cellular structure is developed. 6 Foaming agents can be either a physical gas or a chemical that decomposes in a polymer melt during processing and releases a gas.
A review of thermoplastic polymer foams for functional applications
网页The microcellular foaming process, typically coupled with supercritical fluid as foaming agents, endows thermoplastics with elevated impact strength, increased toughness, and lightweight characteristics in comparison with their solid counterparts [1].
Introduction on Foam Manufacture - SpringerLink
网页A liquid or gas foaming agent is added to the plastic and is released during the melting process. In some cases, such as fluoropolymers, a solid nucleating agent, which is stable at the process temperature, is used.
