conservation mat board
Conservation mat board represents a crucial advancement in archival framing materials, specifically engineered to protect and preserve valuable artwork, photographs, and documents. This specialized board is manufactured using 100% cotton fiber or highly purified wood pulp, ensuring it remains free from lignin, acids, and other harmful compounds that could potentially damage precious items over time. The boards feature a neutral or slightly alkaline pH level, typically ranging between 7.0 and 8.5, which creates an optimal environment for preservation. Their construction includes multiple layers of high-quality materials, with a solid core sandwiched between surface papers that provide both structural integrity and aesthetic appeal. Conservation mat boards are available in various thicknesses, typically ranging from 2-ply to 8-ply, allowing for different levels of depth and presentation options. These boards also incorporate buffering agents that actively neutralize acids and pollutants, providing long-term protection against environmental factors. The materials used meet museum-quality standards and are tested for durability and color fastness, ensuring they maintain their protective properties and appearance for decades.
