Polyurethane green synthesis process: prepared from CO2 as raw material

Carbon dioxide is produced in large quantities as a by-product of many industrial processes, resulting in a sustained increase in atmospheric carbon dioxide concentrations above 420 ppm. This increase has raised serious concerns about climate change and prompted global efforts to mitigate its impacts.

Causes and solutions of yellowing of polyurethane sponge

The yellowing of polyurethane sponge has always been a problem that plagues sponge manufacturers and polyol manufacturers. Many sponge manufacturers, especially some high-end sponge manufacturers, have tried to improve the anti-yellowing performance of sponge by adding antioxidants and light stabilizers, but the results are not significant. In this article, we will analyze the causes of yellowing of sponge systematically based on the upstream and downstream characteristics of polyol and sponge production, and elaborate the corresponding solutions.

A brief introduction to flexible polyurethane foam
