Eco-Friendly Polyurethane Flexible Foam Catalyst with Reduced Emissions
Abstract
The development of eco-friendly polyurethane (PU) flexible foam catalysts is a crucial step towards sustainable manufacturing in the polymer industry. Traditional catalysts often release harmful emissions, contributing to environmental pollution and health risks. This article explores an innovative eco-friendly PU flexible foam catalyst designed to significantly reduce emissions while maintaining high performance. By integrating detailed product parameters, comparative analysis, and referencing international and domestic literature, this paper aims to provide a comprehensive understanding of the advancements in eco-friendly catalyst technology.
