Material bending stiffness performance tester

Material bending stiffness performance testerAlso known as composite material bending stiffness performance tester, material bending testing machine, bending strength performance tester, bending performance tester, it is produced by Shenzhen Puyun Electronics Co., Ltd. PY-H609 paper and cardboard bending stiffness tester, which is suitable for stiffness testing of various types of paper, thin paper boards, films, and thin sheets. The instrument adopts a new testing structure, with convenient sample clamping and one click operation during the testing process. The large LCD display provided by the stiffness tester can intuitively display the entire testing process curve, making it a commonly used testing equipment in paper stiffness testing.

Testing principle:

By measuring the force or moment required for one end of the clamped specimen to bend to a given angle (15 degrees), this force acts on a constant bending length (50mm), and the stiffness value is measured by a high-precision sensor in the stiffness meter

Detection range:

PVA coated high barrier film, biaxially oriented polypropylene film (BOPP film), low-density polyethylene film (LDPE film), polyester film (PET film), nylon film (PA film), cast polypropylene film (CPP film), polyethylene film (PE film), polystyrene film (PS film), polypropylene film (PPE film), aluminum plated film, etc.

---------------------------------------

The testing of material bending stiffness performance is a core testing item for evaluating the ability of materials to resist bending deformation. By quantifying the rigidity and toughness of materials under stress and bending, it intuitively reflects the mechanical stability of materials. It is widely used in the research and development, production, and quality control of various materials such as flexible electronics, films, paper, and boards.

The core significance of this test is to provide accurate quantitative basis for material selection, process optimization, and product qualification judgment, and to avoid in advance the use defects caused by inadequate stiffness, such as flexible electronic substrates that are prone to wrinkling due to low stiffness, difficult to bend due to high stiffness, packaging materials that are prone to damage due to insufficient stiffness, and difficult to form due to high stiffness. At the same time, the test data can meet downstream customer audits and industry standard compliance requirements, providing quality endorsement for product shipments.
