Title: Peng Bai’s Innovations in Physical Foaming

Introduction

Peng Bai is an inventor based in Nanjing, China, whose work focuses on physical foaming processes and materials. His listed portfolio includes 3 patents, including inventions aimed at improving foam uniformity, production efficiency, and environmental performance.

Latest Patents

One of Bai’s latest inventions, “Process for Foaming Using Carbon Dioxide Solution,” describes a two-stage foaming method. A parison is first placed in a carbon dioxide solution for primary foaming, then removed and placed in the solution again for secondary foaming. The process is designed to produce a uniform foam structure and a high foaming rate, including for highly crystalline polymers. By controlling temperature and pressure, the method also aims to improve carbon dioxide penetration and solubility before the subsequent heat-foaming stage.

Another invention, “Environmentally Friendly, Efficient and Low-Cost Method for Preparing Physical Foaming Materials,” uses a reaction kettle to prepare foamed plates. The plates are soaked in water or another permeable medium, saturated with inert gas, and then foamed at a temperature of at least 80°C. The approach is intended to shorten saturation time and improve production efficiency, pore-size homogeneity, pore distribution, and foaming rate.

Career Highlights

Bai’s listed work connects materials processing with practical manufacturing goals. His inventions address ways to control gas uptake and foaming conditions while seeking consistent material structures and more efficient production.

Collaborations

Bai has been associated with Jiangsu Daimaoniu New Material Technology Co., Ltd. and DMN Material Technology (Jiangsu) Limited. His listed coworker is Zhenxiu Zhang.
