acid free mat board
Acid free mat board represents a crucial advancement in preservation technology, specifically designed to protect and display valuable artwork, photographs, and documents. This specialized material is manufactured through a precise process that eliminates lignin and maintains a neutral pH level between 7.0 and 8.5, ensuring long-term preservation of mounted items. The board's core and surface papers are treated with calcium carbonate buffer, which actively neutralizes acids and prevents deterioration over time. Unlike standard mat boards, acid free variants are crafted from 100% cotton fiber or highly purified wood pulp, eliminating the risk of yellowing, brittleness, and degradation that commonly occurs with conventional materials. The material features a sophisticated multi-layer construction that provides both structural integrity and conservation properties, making it ideal for museum-quality framing and archival storage solutions. Its versatile nature allows for various applications, from professional gallery displays to home preservation projects, while maintaining consistent quality and protection standards.
