How Industrial Buyers Evaluate Bakelite Sheet Hardness and Density

Industrial buyers assess Bakelite sheet hardness and density through a combination of standardized testing methods and practical evaluations. They typically rely on Shore hardness tests, particularly Shore D for harder materials like Bakelite, to quantify surface resistance to indentation. Density is measured using displacement methods or precision scales. Buyers also consider application-specific requirements, comparing test results to manufacturer specifications and industry standards. Hands-on evaluations, including machining trials and simulated use tests, complement laboratory data. Ultimately, buyers seek Bakelite sheets with optimal hardness and density to ensure durability, dimensional stability, and performance in electrical insulation, mechanical components, and other industrial applications.
