The Science and Art of Glitter Powder: A Comprehensive Guide from a Leading Manufacturer
Introduction
Glitter powder is more than just a decorative additive—it’s a precision-engineered product that combines materials science, optical physics, and industrial design. As a professional glitter powder manufacturer with ISO 9001 certification, we control every aspect of production from polymer selection to surface metallization. This white paper details the technical specifications and innovative applications that set industrial-grade glitter apart from craft-store varieties.
