ASTM D790 Flexural Properties of Recycled Plastics
The ASTM D790 test method is widely recognized as a standard procedure for determining the flexural properties of plastics, including recycled polymers. This service plays a critical role in ensuring the quality and performance of recycled plastic materials used across various industries such as packaging, automotive components, and construction products.
The ASTM D790 test involves subjecting specimens to progressively increasing loads until they fracture or yield. Specimens are typically shaped into rectangular prisms with defined dimensions to ensure uniformity in testing conditions. The flexural strength (MPa) is calculated as the maximum load applied before failure, while the flexural modulus measures a material's stiffness under load.
For recycled plastics, these tests are essential because they help identify potential degradation caused by environmental factors or processing methods during recycling. By measuring these properties, we can ensure that recycled plastic products maintain their structural integrity and mechanical performance comparable to virgin materials.
The test method also provides valuable insights into the compatibility of different types of plastics when mixed in a recycling process. Understanding how various polymers interact under load helps optimize blends for specific applications without compromising on safety or functionality.
Our lab adheres strictly to ASTM D790 guidelines, employing advanced equipment and trained personnel who understand both theoretical principles and practical considerations involved in this type of testing. Specimen preparation is critical; improper handling can lead to misleading results. Therefore, we take extra care ensuring specimens meet specified dimensions before undergoing loading tests.
In addition to flexural strength and modulus, our laboratory uses ASTM D790 to assess other key performance indicators like impact resistance, elongation at break, and hardness. These additional metrics provide comprehensive data needed for decision-making processes within manufacturing plants or research laboratories focusing on sustainable materials development.
