Phenolic resin microspheres surface‐modified with sodium silicate for reducing fire hazard in TPU composites

Abstract

In this article, a sodium silicate surface-modified phenolic resin microsphere (SSMPHM) was prepared to reduce the fire hazard of thermoplastic polyurethane (TPU). The characterization results demonstrated that sodium silicate was successfully deposited on the surface of the phenolic resin microsphere (PHM). The results
