WVTR Calculator The WVTR Calculator app is a powerful and intuitive tool designed to simplify the calculation of Water Vapor Transmission Rate (WVTR) for both individual material layers and complex laminates. Whether you're working in packaging, construction, or any industry where moisture barrier performance is critical, this app delivers precision and flexibility at your fingertips. Key Features: 1. Materials Database - Access a comprehensive "materials database" containing preloaded WVTR values for various materials. - Easily add new materials by specifying their permeability and the conditions under which they were measured (e.g., temperature, humidity). - For existing materials, you can store multiple sets of conditions and WVTR values, allowing you to account for different testing environments. - Modify or update WVTR values in the database as needed, ensuring your data stays accurate and up-to-date. 2. Laminate Database - Save calculated WVTR values for laminates directly into the "laminate database". - Each laminate entry includes the total WVTR value and details of its individual layers, making it easy to track and reuse your designs. 3. WVTR Calculator - Start by selecting a material from the database or adding a new one if necessary. - Input the material's thickness and choose from the available testing conditions stored in the database. - Press the "Calculate" button to instantly obtain the WVTR value for that layer. - For laminates, simply add multiple layers by specifying the material name and thickness for each. The app will automatically recalculate the total WVTR for the entire structure. 4. Save and Reuse Laminates - Once you’ve calculated the WVTR for a laminate, save it with a custom name to the laminate database for future reference. - Need to modify an existing laminate? Add or remove layers, adjust thicknesses, and recalculate the WVTR with ease. 5. Flexible and Customizable - Whether you're analyzing a single layer or a multi-layered laminate, the app adapts to your needs. - Supports a wide range of materials and conditions, ensuring compatibility with diverse applications and industries.
